Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser radar, in particular to a marking device, a laser radar, an electronic device, a laser radar system and a method. BACKGROUND

[0002] With the development of laser radar, laser radar touch technology appears. The technology adopts single-line laser radar. The laser radar is fixed on the top side of the screen. The single laser beam emitted by the laser radar rotates around the rotation axis perpendicular to the screen to form a laser scanning surface on the screen which needs to be touched. When the screen is clicked, the laser beam emitted by the laser radar is blocked, and the specific coordinates of the object clicking the screen are identified, thereby realizing the touch function. However, the distance between the laser scanning surface and the screen is a fixed distance, and the distance between the laser scanning surface and the screen is large. Therefore, the position of the laser scanning surface cannot be adjusted, resulting in large touch error. SUMMARY

[0003] The embodiments of the present application provide a marking device, a laser radar, an electronic device, a laser radar system and a method, which can adjust the position of the laser scanning surface and reduce the touch error.

[0004] In a first aspect, the embodiments of the present application provide a laser radar system. The laser radar system comprises a detection device, a driving assembly, a marking assembly and a control device. The detection device is configured to emit a laser beam. The detection device is also configured to receive the laser beam reflected by a target object. The driving assembly is configured to drive the detection device to rotate around at least one of a first rotation axis and a second rotation axis. The marking assembly comprises at least one marking element. The marking element is configured to reflect the laser beam so that the detection device receives a reflected signal. The reflected signal is a signal reflected by the marking element after the laser beam emitted by the detection device irradiates the marking element. The control device is in communication connection with the driving assembly. The control device is configured to control the driving assembly to drive the detection device to move according to the reflected signal, so as to correct the posture of the detection device.

[0005] The detection device emits the laser beam to form a laser scanning surface. In the process of adjusting the position of the laser scanning surface, the control device controls the driving assembly to drive the detection device to move. For example, the driving assembly drives the detection device to rotate around the first rotation axis. When the detection device scans the marking element, the detection device can receive the reflected signal. The control device can control the driving assembly to drive the detection device to perform corresponding operations according to the reflected signal, such as stopping the movement of the detection device when the marking element is scanned. By making the detection device scan the marking element, the posture of the detection device can be corrected, thereby indirectly adjusting the position of the laser scanning surface and adjusting the distance between the laser scanning surface and the display screen.

[0006] Therefore, by controlling the driving assembly to drive the detection device to move according to the reflection signal, the posture of the detection device can be automatically adjusted, the distance between the laser scanning surface and the display screen can be automatically adjusted, the position of the laser scanning surface can be corrected, the problem of large touch error and inaccurate positioning caused by the large distance between the laser scanning surface and the display screen can be avoided, and the touch error can be reduced. In addition, the problems caused by manually adjusting the distance between the laser scanning surface and the screen in the related art, such as the need to use a device that can view the laser beam and repeated adjustment, can be solved. In the embodiment of the present application, the adjustment can be performed without using a device that can view the laser beam, the adjustment difficulty can be reduced, and the adjustment efficiency can be improved.

[0007] In some possible implementation manners, the identification member can be a communication-capable electronic device, which can also be referred to as an identification device; or the identification member can also be a general identification object without communication capability.

[0008] In some possible implementation manners, the identification member includes a first part, the reflectivity of the first part is higher than that of at least part of the rest of the identification member, and the first part is configured to generate a first reflection signal received by the detection device. The reflection signal includes the first reflection signal, and the control device is configured to control the driving assembly to drive the detection device to move according to the reflection signal, including: the control device is configured to control the driving assembly to drive the detection device to move according to the first reflection signal.

[0009] In this way, the driving assembly can be controlled to perform corresponding operations according to whether the laser beam scans the first part.

[0010] In some possible implementation manners, the identification member further includes a second part, and the reflectivity of the first part to the laser beam is greater than that of the second part to the laser beam.

[0011] In this way, the driving assembly can be controlled to drive the detection device to perform corresponding operations according to the energy of the laser beam reflected by the identification member, for example, the driving assembly controls the detection device to continue rotating or stop rotating, so as to control the movement of the detection device, and further correct the posture of the detection device.

[0012] In some possible implementation manners, the control device is configured to control the driving assembly to drive the detection device to move based on the reflectivity change information determined based on the reflectivity change between the first part and the second part. The reflected signal further includes a second reflected signal, and the control device is configured to control the driving assembly to drive the detection device to move according to the reflected signal, including: the control device is configured to control the driving assembly to drive the detection device to move according to the first reflected signal and the second reflected signal. The second part is configured to generate the second reflected signal that can be received by the detection device, or the second part is unable to generate the second reflected signal that can be received by the detection device, or the second reflected signal generated by the second part cannot be received by the detection device.

[0013] In this way, the reflectivity of the first part and the second part to the laser beam is different, so that the first reflected signal and the second reflected signal are different, and the driving assembly can be controlled to drive the detection device to perform corresponding operations according to the difference between the first reflected signal and the second reflected signal, for example, when the detection device scans the first part, the detection device is controlled to stop moving.

[0014] In some possible implementation manners, the control device is configured to control the driving assembly to drive the detection device to move based on the reflectivity change information determined based on the reflectivity change between the first part and the second part, including: when the laser beam emitted by the detection device scans from the second part to the first part, the driving assembly is controlled to drive the detection device to stop moving according to the reflectivity change information.

[0015] In this way, the time when the detection device is controlled to stop moving can be controlled, so that the distance between the position of the laser scanning surface and the display screen is within a preset range.

[0016] In some possible implementation manners, the reflectivity change information includes information about the intensity change of the laser beam received by the detection device due to the reflectivity change, and the driving assembly is controlled to drive the detection device to stop moving according to the reflectivity change information, including: when the intensity change of the laser beam satisfies a preset condition, the driving assembly is controlled to drive the detection device to stop moving.

[0017] In this way, the difficulty of controlling the detection device to stop moving can be reduced.

[0018] In some possible implementation manners, when the intensity change of the laser beam satisfies a preset condition, the driving assembly is controlled to drive the detection device to stop moving, including: when a peak value appears in an intensity curve of the laser beam, the driving assembly is controlled to drive the detection device to stop moving.

[0019] In this way, the detection device can be controlled to stop moving when the intensity of the laser beam changes.

[0020] In some possible implementation manners, before the control device controls the driving assembly according to the reflection signal, the control device is further configured to control the driving assembly to drive the detection device to move along the preset track, so as to adjust the detection device to the to-be-adjusted posture.

[0021] In this way, the detection device is first adjusted to the to-be-adjusted posture, and then the driving assembly is controlled to drive the adjustment device to move, in the process, the driving assembly is controlled to move according to the reflection signal, so that the detection device is controlled to perform corresponding operations, and then the posture of the detection device is corrected, thereby achieving the purpose of correcting the position of the laser scanning surface.

[0022] In some possible implementation manners, in response to the adjustment signal, the control device controls the driving assembly to drive the detection device to move along the preset track, so as to adjust the detection device to the to-be-adjusted posture.

[0023] In this way, the detection device can be adjusted to the to-be-adjusted posture when the user needs to adjust the laser scanning surface.

[0024] In some possible implementation manners, the adjustment signal is a signal generated by the marker itself or a signal generated by other equipment.

[0025] In some possible implementation manners, the detection device is configured to be mounted on the side of the display screen. Before the control device controls the driving assembly according to the reflection signal, the control device is further configured to control the driving assembly to drive the detection device to move away from the display screen, and / or the control device is further configured to control the driving assembly to drive the detection device to move towards the display screen, so as to obtain the reflectivity change information. The reflectivity change information is information determined based on the reflectivity change between the first part and the second part of the marker.

[0026] Because different markers have different sizes, the reflectivity change information of the marker scanned by the detection device is different. By allowing the detection device to scan the marker before the posture of the detection device is corrected, accurate reflectivity change information can be obtained, or the obtained reflectivity change information can be corrected, so as to adjust the correction accuracy.

[0027] In some possible implementation manners, the control device is configured to control the driving assembly to drive the detection device to move according to the reflection signal, including: controlling the driving assembly to drive the detection device to rotate around the first rotation axis, so as to adjust the detection device to the first posture.

[0028] In this way, the detection device can be adjusted to the to-be-adjusted posture when the user needs to adjust the laser scanning surface.

[0029] In some possible implementation manners, the identification member is one, and the identification member is used to click a target identification point of the display screen, and the target identification point includes the first identification point. When the identification member clicks the first identification point, the control driving assembly is controlled to drive the detection device to rotate around the first rotation axis, so as to adjust the detection device to the first posture.

[0030] In this way, after the identification member clicks the first identification point, the detection device can be adjusted from the standby posture to the first posture, and it is ensured that the detection device can scan the identification member during movement of the detection device.

[0031] In some possible implementation manners, the target identification point further includes a second identification point. When the identification member clicks the second identification point, the control driving assembly is controlled to drive the detection device to rotate around the second rotation axis, so as to adjust the detection device from the first posture to the second posture.

[0032] In this way, after the identification member clicks the first identification point, the detection device can be adjusted from the first posture to the second posture, and the adjustment operation of the detection device rotating around the second rotation axis can be realized.

[0125] The terms used in the embodiments part of the present application are only used for explaining the specific embodiments of the present application, and are not intended to limit the present application.

[0126] A laser radar (light detection and ranging, LiDAR) is a detection device that detects the position, speed and other characteristic quantities of a target by emitting a detection signal (laser beam). The working principle of the laser radar is to emit a detection signal to a target, and then compare and process the echo signal reflected by the target with the detection signal, so as to obtain information about the target, such as the distance of the target, the direction of the target, the speed of the target, the attitude of the target, and even the shape of the target, etc. Thus, the target can be detected, tracked and identified.

[0127] The application relates to laser radar touch technology, that is, screen touch is realized through laser radar. In the application, a smart large screen (or television) comprises a laser radar and a screen. Exemplarily, the laser radar can be a single-line laser radar, the laser radar is fixedly connected to the top side of the screen, a motor is arranged in the laser radar, the motor can drive a laser transceiver of the laser radar to rotate by 360 DEG, so that a single laser beam emitted by the laser radar rotates by 360 DEG around an axis of rotation, and a laser scanning surface is formed on the surface of the screen. When an object clicks the screen, the laser beam emitted by the laser radar is blocked, so that the specific coordinates of the object clicking the screen are recognized, and the touch function is realized.

[0128] Since the screen and the laser radar are fixedly connected, the relative position of the laser radar and the screen cannot be adjusted, that is, the posture of the laser radar cannot be adjusted, so that the distance between the screen and the laser scanning surface is a fixed distance, and the distance between the laser scanning surface and the screen cannot be adjusted. Due to the assembly error of the television, the vibration of the television in the transportation process and other factors, the laser scanning surface will be on the screen or the distance between the laser scanning surface and the screen will be large, resulting in problems such as large touch error and inaccurate positioning.

[0129] In an embodiment, the laser radar is installed on the screen through an adjusting device. The adjusting device comprises a first connecting component, a second connecting component, an elastic support and an adjusting bolt. The first connecting component and the second connecting component are movably connected. One of the first connecting component and the second connecting component is fixedly connected with the laser radar, and the other is fixedly connected with the screen. The elastic support is arranged between the first connecting component and the second connecting component. The adjusting bolt passes through one of the first connecting component and the second connecting component and is threadedly connected with the other.

[0130] When the distance between the laser scanning surface and the screen is out of a reasonable range, the adjusting bolt is manually screwed, so that the included angle between the first connecting component and the second connecting component changes, thereby adjusting the distance between the laser scanning surface and the screen. However, since the laser beam emitted by the laser radar cannot be directly observed by the human eye, it is necessary to repeatedly adjust the distance between the laser scanning surface and the screen to a reasonable range by means of a device capable of observing the laser beam and corresponding measuring tools, and the whole adjustment process is time-consuming and laborious, and the efficiency is low. In addition, for users, they usually do not have a device that can observe the laser beam. At this time, the distance between the laser scanning surface and the screen is adjusted by feeling, and the adjustment result is verified by the object touch mode. The whole process needs a lot of time and energy and may not be adjusted in place.

[0131] Therefore, the laser radar system 100 provided in the embodiments of the present application can automatically adjust the distance between the laser scanning surface and the screen, can avoid the problem that the distance between the laser scanning surface and the screen is too large, and can also solve the problem caused by manually adjusting the distance between the laser scanning surface and the screen, for example, the adjustment can be performed without the aid of a device capable of viewing the laser beam, and the position of the laser scanning surface can be adjusted by the user.

[0132] The laser radar system 100 provided in the embodiments of the present application can be applied to an electronic device with a display screen 200, such as a smart screen or an office whiteboard. The display screen 200 can also be referred to as a screen or the like. Alternatively, the laser radar system 100 can also be applied to an electronic device capable of generating a display area or having a matching display cloth, such as a projector.

[0133] The laser radar system 100 provided in the embodiments of the present application can be applied to an electronic system including the laser radar system 100 and an electronic device for communicating with the laser radar system 100. The electronic device can interact with the laser radar system 100 through communication to realize a corresponding function scene. For example, when the electronic device is a smart large screen, the smart large screen can obtain real-time collection data through communication with the laser radar system 100 to realize handwriting or touch interaction between the user and the large screen.

[0134] For ease of description, the laser radar system 100 is applied to an electronic device with a display screen 200 in the embodiments of the present application.

[0135] Figure 1 A touch diagram of the display screen using the laser radar system is provided in the embodiments of the present application. Figure 1 The laser radar system 100 in the embodiments of the present application is only used to illustrate the function of the laser radar system 100,The structure of the laser radar system 100 in the embodiments of the present application does not limit the specific structure of the laser radar system 100. Figure 1

[0136] As shown in the example, Figure 1 As shown in the example, the electronic device includes a display screen 200 and a laser radar system 100. The laser radar system 100 can emit a laser beam on the display side of the display screen 200. The laser beam can rotate 360° around the rotation axis to form a laser scanning surface. After a target object clicks the display screen 200, the target object blocks the laser beam and generates a reflected light beam. The laser radar system 100 can also receive the reflected light beam. According to the reflected light beam returned to the laser radar system 100, the distance and angle of the target object relative to the laser radar system 100 can be obtained after signal processing, so as to realize touch and handwriting functions and improve user experience.

[0137] The rotation axis intersects with the display surface of the display screen 200 and does not coincide with the display surface, for example, the rotation axis can be perpendicular to the display surface of the display screen 200.

[0138] Optionally, in some designs, the laser beams emitted by the laser radar system 100 can also be scanned by 180°, or other angle ranges according to specific application scenarios and interactive experiences, or even dynamically adjust the scanning angle range during execution according to changes in the interactive scene or user intent, etc.

[0139] Figure 2 A structural schematic diagram of a laser radar system provided by an embodiment of the present application.

[0140] Referring to Figure 2 , the laser radar system 100 includes a detection device 110, a driving assembly 120, an identification assembly 130, and a control device (not shown in the figure). The driving assembly 120 is fixedly connected to the display screen 200, and the detection device 110 is fixedly connected to the display screen 200 and drivingly connected to the driving assembly 120. The identification assembly 130 can be fixedly connected to the display screen 200, or the identification assembly 130 and the display screen 200 are in a split structure and are used to click the display screen 200 (as shown in Figure 2 ).

[0141] In an embodiment of the present application, referring to Figure 2 , the detection device 110 is used to emit laser beams to form a laser scanning surface, and the detection device 110 is also used to receive laser beams reflected by target objects. Therefore, the detection device 110 can emit and receive laser beams, realize the transceiving of laser beams, and further realize laser scanning.

[0142] In some embodiments, the name of the detection device 110 can also be a detection assembly.

[0143] In some embodiments, the detection device 110 and the driving assembly 120 can be parts of a laser radar, that is, the laser radar includes the detection device 110 and the driving assembly 120, and the laser radar is installed on the side of the display screen 200, for example, on the upper frame of the display screen 200.

[0144] In some embodiments, the detection device 110 can be arranged on the driving assembly 120, and the detection device 110 can be connected to the display screen 200 through the driving assembly 120. Or in some embodiments, the detection device 110 can also be directly and movably arranged on the display screen 200.

[0145] The driving assembly 120 is fixedly connected to the outer frame of the display screen 200, specifically, as Figure 2As shown, the driving assembly 120 can be mounted on the top side of the display screen 200. Of course, the driving assembly 120 can also be mounted on other sides of the display screen 200, for example, the driving assembly 120 can also be mounted on the bottom side, left side or right side of the display screen 200. In addition, the driving assembly 120 and the detection device 110 are arranged on the same side of the display screen 200, for example, the driving assembly 120 and the detection device 110 are both arranged on the top side of the display screen 200.

[0146] Figure 3 For Figure 2 the detection device cooperates with the driving assembly. It should be noted that Figure 3 the shape and structure of the detection device 110 in do not constitute a limitation on the specific structure and specific shape of the detection device 110, and are only used to illustrate the positional relationship thereof with the driving assembly 120 and the display screen 200. Figure 3 the shape and structure of the driving assembly 120 in do not constitute a limitation on the specific structure and specific shape of the driving assembly 120, and are only used to illustrate the positional relationship thereof with the detection device 110 and the display screen 200.

[0147] In the embodiments of the present application, referring to Figure 3 , the driving assembly 120 is configured to drive the detection device 110 to rotate around at least one of the first rotation axis and the second rotation axis. Wherein, the orthogonal projection of the first rotation axis and the second rotation axis on the projection plane intersect and do not coincide, at this time, the included angle between the orthogonal projection of the first rotation axis and the second rotation axis on the projection plane can include but is not limited to 90°, 85°, etc. Wherein, in some embodiments, the projection plane can be a plane perpendicular to the horizontal plane.

[0148] In some embodiments, one of the first rotation axis and the second rotation axis is perpendicular to the horizontal plane, and the other is parallel to the horizontal plane, for example, referring to Figure 3 , the first rotation axis is parallel to the horizontal plane, and the second rotation axis is perpendicular to the horizontal plane, at this time, the detection device 110 can be pitch-rotated around the first rotation axis, and the detection device 110 can be horizontally rotated around the second rotation axis.

[0149] Wherein, the horizontal plane is perpendicular to the plane in which the length direction and the width direction of the display screen 200 are located, and is parallel to the thickness direction of the display screen 200. In addition, when the first rotation axis is parallel to the horizontal plane, the first rotation axis can be parallel to the length direction of the display screen 200, and when the second rotation axis is parallel to the horizontal plane, the second rotation axis can be parallel to the width direction of the display screen 200.

[0150] In the embodiments of the present application, the identification assembly 130 includes at least one identification piece 131, for example Figure 2As shown, the number of the markers 131 is one, and the number of the markers 131 can also be multiple. The markers 131 are arranged on the display side of the display screen 200 and are spaced apart from the detection device 110, that is, the markers 131 are arranged on the side of the display screen 200 facing the user. The markers 131 are used to reflect the laser beam so that the detection device 110 receives the reflected signal, which is the signal reflected by the markers 131 after the laser beam emitted by the detection device 110 irradiates the markers 131.

[0151] In the embodiment, the control device is in communication connection with the driving assembly 120, and the control device is used to control the driving assembly 120 to drive the detection device 110 to move according to the reflected signal, so as to correct the posture of the detection device 110 and achieve the purpose of adjusting the position of the laser scanning surface.

[0152] In some embodiments, the control device can be a control device separately arranged in the laser radar system 100. Or in some embodiments, the control device can also be a control device of the electronic device or a control device of the detection device 110.

[0153] In the process of adjusting the laser scanning surface, the control device controls the driving assembly 120 to drive the detection device 110 to move, for example, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis, and when the detection device 110 scans the marker 131, the detection device 110 can receive the reflected signal. The control device can control the driving assembly 120 to drive the detection device 110 to perform corresponding operations according to the reflected signal, such as stopping the movement of the detection device 110 when scanning the marker 131. By allowing the detection device 110 to scan the marker 131, the posture of the detection device 110 can be corrected, thereby indirectly adjusting the position of the laser scanning surface and further adjusting the distance between the laser scanning surface and the display screen 200.

[0154] Therefore, by controlling the driving assembly 120 to drive the detection device 110 to move according to the reflected signal through the control device, the posture of the detection device 110 can be automatically adjusted, the distance between the laser scanning surface and the display screen 200 can be automatically adjusted, the position of the laser scanning surface can be automatically corrected, and the problem of large touch error and inaccurate positioning caused by the large distance between the laser scanning surface and the display screen 200 can be avoided to reduce the touch error. In addition, the problems caused by manually adjusting the distance between the laser scanning surface and the screen in the related art, such as the need to use a device that can view the laser beam and repeated adjustment, can be solved. In the embodiment, the adjustment can be performed without the aid of a device that can view the laser beam, the adjustment difficulty can be reduced, and the adjustment efficiency can be improved.

[0155] It should be noted that the present application does not limit how to determine whether the detection device 110 scans the marker 131 according to the reflected signal. For example, the detection device 110 can determine whether the detection device 110 scans the marker 131 according to the intensity of the laser beam reflected by the marker 131.

[0156] It should be noted that when the number of markers 131 is one, the marker 131 can click different positions of the display screen 200 during the adjustment of the laser scanning surface, so that the same marker 131 is located at multiple different marker positions, and the detection device 110 can scan the marker 131 at the multiple different marker positions during the correction process.

[0157] Figure 4 A layout diagram of multiple markers provided by an embodiment of the present application.

[0158] In an embodiment of the present application, the display screen 200 has at least two markers, for example Figure 4 As shown, the number of markers is two, and the two markers are a first marker and a second marker, respectively. Each marker is used to contact the marker 131, for example, the marker 131 clicks the marker or is fixedly connected to the position where the marker is located. In this way, when the user holds the marker 131, it is not necessary to ensure the size of the distance between the display screen 200 and the marker 131, which can reduce the correction difficulty and improve the correction accuracy.

[0159] When the marker 131 clicks the marker, the marker 131 and the display screen 200 are in a split structure, and the marker 131 is not fixedly connected to the display screen 200. In addition, when the marker 131 clicks the marker, the position where the marker 131 is located is a marker position, and when the marker 131 clicks different positions, the marker position where the marker 131 is located is different.

[0160] When the marker 131 is fixedly connected to the position where the marker is located, the marker 131 is fixedly connected to the display screen 200. In addition, when the marker 131 is fixedly connected to the marker, the position where the marker 131 is located is a marker position, and when the marker 131 is fixedly connected to different positions, the marker position where the marker 131 is located is different.

[0161] In a possible implementation, the multiple markers of the display screen 200 can include a first marker and a second marker. The first marker of the display screen 200 can be located below the laser radar, and the first marker is located on or close to the first axis, the first axis is parallel to the height direction of the display screen 200 and passes through the laser radar. Of course, the first marker can also not be located below the laser radar, and the first marker can also be located on the left side or the right side of the laser radar.

[0162] When the first identification point is below the laser radar, the second identification point of the display screen 200 can be located on the left side and the right side of the first identification point along the length direction of the display screen 200.

[0163] Figure 5 Another layout diagram of multiple identification points provided by an embodiment of the present application.

[0164] In some embodiments, referring to Figure 4 , the number of identification points can be two, and the two identification points can be a first identification point and a second identification point, respectively. The first identification point and the second identification point can be arranged side by side and spaced apart along the length direction of the display screen 200 (such as the X direction in Figure 4 ). The first identification point and the detection device 110 can be arranged side by side and spaced apart along the width direction of the display screen 200 (such as the Y direction in Figure 4 ). The first identification point and the second identification point can both be close to the bottom side of the display screen 200. Along the length direction of the display screen 200, the second identification point can be arranged on the left side (as shown in Figure 4 ) or the right side (as shown in Figure 5 ) of the first identification point. Wherein, the left side and the right side are the relative positions of the first identification point and the second identification point with reference to the user facing the display screen 200.

[0165] Figure 6 Another layout diagram of multiple identification points provided by an embodiment of the present application.

[0166] Of course, the layout of the first identification point and the second identification point can also be other layouts besides the layouts shown in Figure 4 and Figure 5 . In some embodiments, referring to Figure 6 , the first identification point and the second identification point can be arranged on the two sides of the detection device 110 along the length direction of the display screen 200. The first identification point and the second identification point are arranged side by side and spaced apart along the length direction of the display screen 200. The first identification point and the second identification point are both arranged spaced apart from the detection device 110 along the width direction of the display screen 200.

[0167] Alternatively, in some embodiments, the first identification point and the detection device 110 are arranged side by side and spaced apart along the width direction of the display screen 200. The first identification point is close to the bottom side of the display screen 200. Along the width direction of the display screen 200, the second identification point is located between the detection device 110 and the first identification point. The second identification point is close to the left side or the right side of the display screen 200 and is located between the first identification point and the detection device 110 along the width direction of the display screen 200.

[0168] Figure 7 Another layout diagram of multiple identification points provided by an embodiment of the present application.

[0169] In some embodiments, referring to Figure 7 , the number of identification points can be three, and the three identification points can be a first identification point, a second identification point, and a third identification point, respectively. The first identification point, the third identification point, and the third identification point can be arranged at three corners of the display screen 200, respectively. The first identification point and the second identification point can be arranged on the same side of the display screen 200 and close to the bottom side of the display screen 200. Along the width direction of the display screen 200, the third identification point can be located between the first identification point and the detection device 110 and can be close to the left side or the right side of the display screen 200 (as shown in Figure 7 ).

[0170] Alternatively, in some embodiments, the first identification point, the second identification point, and the third identification point can be arranged side by side and spaced apart along the length direction of the display screen 200. The first identification point, the second identification point, and the third identification point can all be arranged spaced apart from the detection device 110 along the width direction of the display screen 200. The first identification point and the detection device 110 can be arranged side by side and spaced apart along the width direction of the display screen 200.

[0171] Alternatively, in some embodiments, the first identification point and the detection device 110 can be arranged side by side and spaced apart along the width direction of the display screen 200. Along the width direction of the display screen 200, the second identification point and the third identification point can be arranged side by side and spaced apart along the length direction of the display screen 200 and close to the left side and the right side of the display screen 200, respectively. Along the width direction of the display screen 200, the second identification point and the third identification point can both be located between the first identification point and the detection device 110.

[0172] Figure 8 Another layout diagram of multiple identification points provided by the embodiments of the present application

[0173] In some embodiments, referring to Figure 8 , the number of identification points can be four, and the four identification points can be arranged at four corners of the display screen 200, respectively.

[0174] It should be noted that the layout of the multiple identification points can include but is not limited to the several layouts described above.

[0175] In some possible implementation manners, referring to Figure 4 , the number of identification members 131 is one, and the identification member 131 is used to click at least two identification points of the display screen 200 in sequence. At this time, the identification member 131 and the display screen 200 are in a split structure. In this way, the identification member 131 does not need to be fixedly connected to the display screen 200, thereby avoiding that the identification member 131 affects the appearance delicacy of the display side of the display screen 200.

[0176] It should be noted that when the number of the identification member 131 is one, in addition to clicking the display screen 200, in some possible implementation manners, when the number of the identification member 131 is one, the identification member 131 can also be detachably connected with the display screen 200, for example, the identification member 131 can be magnetically connected with the display screen 200, in the process of adjusting the laser scanning surface, the identification member 131 can be quickly detached from the display screen 200 and fixed on different positions of the display screen 200, without manually making the identification member always in contact with the display screen 200, so that the labor intensity of the user can be reduced and the user experience can be improved.

[0178] In some possible implementation manners, referring to Figure 9 , the identification assembly 130 includes a plurality of identification members 131 arranged at intervals, for example, the number of the identification members 131 is 2, 3, 4 or the like, and each identification member 131 is fixedly connected to the display side of the display screen 200. The display screen 200 has at least two identification points, and each identification point is fixedly connected with one identification member 131. In this way, by fixing the identification member 131 on the display screen 200, the user does not need to always hold the identification member 131 by hand, and the user can not need to participate in the adjustment, thereby further improving the user experience and the correction efficiency.

[0179] Among them, the layout of the plurality of identification members 131 is the same as the layout of the plurality of identification points, and several layouts of the plurality of identification members 131 are described below.

[0180] In some embodiments, the two identification members 131 are arranged at intervals along the width direction of the display screen 200 and the detection device 110, and the two identification members 131 are fixedly connected to the first identification point and the second identification point respectively. Among them, along the length direction of the display screen 200, the second identification point can be located on the left side (as shown in Figure 9 ) or the right side (as shown in Figure 10 ) of the first identification point, or referring to Figure 11 , the first identification point and the second identification point are respectively located on the two sides of the detection device 110.

[0181] Or, in some embodiments, referring to Figure 12The identification member 131 fixedly connected to the first identification point is arranged side by side and spaced apart with the detection device 110 along the width direction of the display screen 200, and the identification member 131 fixedly connected to the second identification point can be close to the left side or the right side of the display screen 200 (as shown in Figure 12 The identification member 131 fixedly connected to the second identification point is located between the first identification point and the detection device 110 along the width direction of the display screen 200.

[0182] Alternatively, in some embodiments, referring to Figure 13 The identification member 131 fixedly connected to the first identification point is arranged side by side and spaced apart with the detection device 110 along the width direction of the display screen 200, and the identification member 131 fixedly connected to the second identification point and the identification member 131 fixedly connected to the third identification point are both located between the first identification point and the detection device 110 along the width direction of the display screen 200.

[0183] It should be noted that the layout of the plurality of identification members 131 can include but is not limited to the several layouts described above.

[0184] In some possible implementation manners, the material of at least part of the identification member 131 includes high-reflectivity material, and the reflectivity of the high-reflectivity material is relatively high. For example, the reflectivity of the high-reflectivity material can be 85%. Since the reflectivity of the high-reflectivity material is relatively high, the reflectivity of the high-reflectivity material to the laser beam is high, which can improve the energy of the laser beam reflected by the identification member 131 and received by the detection device 110, that is, the intensity of the laser beam reflected by the identification member 131 and received by the detection device 110. Therefore, according to the processing of the reflected signal received by the detection device 110, it can be determined whether the laser beam emitted by the detection device 110 scans the high-reflectivity material, and thus whether the detection device 110 scans the identification member 131.

[0185] The high-reflectivity material can also be referred to as high-reflectivity material. In addition, the high-reflectivity material can include but is not limited to silver fiber conductive cloth and ITO composite conductive film.

[0186] Figure 14 Another structural schematic diagram of the laser radar system provided by the embodiment of the present application.

[0187] In some possible implementation manners, referring to Figure 14The identification member 131 comprises a first part 132, the reflectivity of the first part 132 is higher than that of at least part of the rest of the identification member 131, and the first part 132 is configured to generate a first reflected signal received by the detection device 110. The reflected signal comprises the first reflected signal, and the control device is configured to control the driving assembly 120 to drive the detection device 110 to move according to the reflected signal, including: the control device is configured to control the driving assembly 120 to drive the detection device 110 to move according to the first reflected signal. In this way, the posture of the detection device 110 can be adjusted to the preset posture to correct the posture of the detection device 110 by controlling the movement of the detection device 110 through the first reflected signal.

[0188] In some possible implementation manners, the material of the first part 132 comprises high-reflectivity material, the reflectivity of the first part 132 to the laser beam is relatively high, the intensity of the laser beam reflected by the first part 132 to the detection device 110 is relatively large, and the detection device 110 can perform corresponding actions according to the first reflected signal, for example, the detection device 110 can stop moving according to the first reflected signal.

[0189] In some possible implementation manners, referring to Figure 14 The identification member 131 further comprises a second part 133, and the reflectivity of the first part 132 to the laser beam is greater than that of the second part 133 to the laser beam. In this way, the reflected signals formed by the laser beams reflected by the first part 132 and the second part 133 are different, the detection device 110 can be determined to scan to which surface area of the identification member 131 by processing the reflected signals, and then the driving assembly 120 can perform corresponding control operations, for example, the driving assembly 120 can control the detection device 110 to continue rotating or stop rotating, so as to control the movement of the detection device 110, and further correct the posture of the detection device 110.

[0190] In some embodiments, the material of the first part 132 and the material of the second part 133 both comprise high-reflectivity material, and the reflectivity of the high-reflectivity material of the first part 132 is different from that of the second part 133, so as to ensure that the reflectivity of the first part 132 to the laser beam is greater than that of the second part 133 to the laser beam.

[0191] Or in some embodiments, the material of the first part 131 comprises high-reflectivity material, and the material of the second part 133 does not comprise high-reflectivity material, so that the reflectivity of the first part 132 to the laser beam is greater than that of the second part 133 to the laser beam.

[0192] The number of the first parts 132 can be one or more, and the number of the second parts 133 can also be one or more. Therefore, in some embodiments, the number of the first parts 132 and the number of the second parts 133 are both one. Alternatively, in some embodiments, the number of one of the first parts 132 and the second parts 133 can be one, and the number of the other can be more. Alternatively, in some embodiments, the number of the first parts 132 and the number of the second parts 133 can both be more, and the first parts 132 and the second parts 133 can be arranged alternately.

[0193] It should be noted that when the number of the first parts 132 is more, the reflectivity of any two second parts 133 to the laser beam can be different, or the reflectivity of any two second parts 133 to the laser beam can be the same, or the reflectivity of a part of the second parts 133 to the laser beam can be different, and the reflectivity of another part of the second parts 133 to the laser beam can be the same.

[0194] When the number of the materials of the first parts 132 is more, at least two of the materials can include high-reflectivity materials with different reflectivity, or at least two of the materials can include high-reflectivity materials with the same reflectivity.

[0195] It should be noted that when the number of the second parts 133 is more, the reflectivity of any two second parts 133 to the laser beam can be different, or the reflectivity of any two second parts 133 to the laser beam can be the same, or the reflectivity of a part of the second parts 133 to the laser beam can be different, and the reflectivity of another part of the second parts 133 to the laser beam can be the same.

[0196] In some possible implementation manners, the control device is configured to control the driving assembly 120 to drive the detection device 110 to move based on the reflectivity change information determined based on the reflectivity change between the first part 132 and the second part 133. The reflection signal further includes a second reflection signal, and the control device is configured to control the driving assembly 120 to drive the detection device 110 to move according to the reflection signal, including: the control device is configured to control the driving assembly 120 to drive the detection device 110 to move according to the first reflection signal and the second reflection signal. In this way, the detection device 110 can be controlled to perform corresponding operations according to the reflectivity change of the first part 132 and the second part 133 of the identification element 131, and the difficulty of controlling the movement of the detection device 110 can be reduced.

[0197] The second part 133 is configured to generate a second reflection signal that can be received by the detection device 110, or the second part 133 is unable to generate a second reflection signal that can be received by the detection device 110, or the second reflection signal generated by the second part 133 cannot be received by the detection device 110.

[0198] Due to the difference in reflectivity between the first part 132 and the second part 133, the reflectivity of the first part 132 and the second part 133 to the laser beam is different, so that the first reflection signal and the second reflection signal are different, and according to the difference between the first reflection signal and the second reflection signal, the control of the detection device 110 can be realized to correct the attitude of the detection device 110.

[0199] In some possible implementation manners, the control device is configured to control the driving assembly 120 to drive the detection device 110 to move based on the reflectivity change information determined according to the reflectivity change between the first part 132 and the second part 133, including: when the laser beam emitted by the detection device 110 is scanned from the second part 133 to the first part 132, the driving assembly 120 is controlled to drive the detection device 110 to stop moving according to the reflectivity change information.

[0200] In some embodiments, the reflectivity change information includes information about the intensity change of the laser beam received by the detection device 110 due to the reflectivity change. Since the reflectivity of the first part 132 and the second part 133 is different, the intensity of the laser beam reflected by the first part 132 and the second part 133 to the detection device 110 is different, that is, the intensity of the laser beam reflected by the first part 132 and the second part 133 changes, and the driving assembly 120 can be controlled to drive the detection device 110 to stop moving according to the intensity change.

[0201] In some embodiments, the driving assembly 120 is controlled to drive the detection device 110 to stop moving when the intensity change of the laser beam satisfies a preset condition, including: the driving assembly 120 is controlled to drive the detection device 110 to stop moving when the intensity curve of the laser beam appears a peak value.

[0202] The intensity curve of the laser beam is a curve formed by the laser beam received by the detection device 110 when the detection device 110 scans the identification member 131, and since the reflectivity of the first part 132 and the second part 133 to the laser beam is different, the intensity of the laser beam reflected by different areas of the identification member 131 received by the detection device 110 is different.

[0203] Alternatively, in some embodiments, the driving assembly 120 is controlled to drive the detection device 110 to stop moving when the intensity change of the laser beam satisfies a preset condition, including: the driving assembly 120 is controlled to drive the detection device 110 to stop moving when the intensity curve of the laser beam appears a peak value and then after a first time.

[0204] In some possible implementation manners, before the control device controls the driving assembly 120 according to the reflection signal, the control device is further configured to control the driving assembly 120 to drive the detection device 110 to move according to a preset trajectory, so as to adjust the detection device 110 to a to-be-adjusted attitude.

[0205] The preset track of the detection device 110 can be rotation of the detection device 110 around the first rotation axis, or the preset track of the detection device 110 can be rotation of the detection device 110 around the first rotation axis and the rotation axis.

[0206] In some possible implementation manners, in response to the adjustment signal, the control device controls the driving assembly 120 to drive the detection device 110 to move according to the preset track, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, the posture of the detection device 110 can be adjusted when the user needs to adjust the laser scanning surface.

[0207] In some possible implementation manners, the adjustment signal is a signal generated by the marker 131 itself or a signal generated by other equipment. The other equipment can be a remote controller for controlling a television, a mobile phone or the like.

[0208] In some possible implementation manners, before the control device controls the driving assembly 120 according to the reflection signal, the control device is further configured to control the driving assembly 120 to drive the detection device 110 to move from the display screen 200 to a direction away from the display screen 200, and / or the control device is further configured to control the driving assembly 120 to drive the detection device 110 to move from the direction away from the display screen 200 to the display screen 200, so as to obtain the reflectivity change information. The reflectivity change information is information determined based on a reflectivity change between the first part 132 and the second part 133 of the marker 131.

[0209] Because different markers 131 have different sizes, the reflectivity change information of the markers 131 scanned by the detection device 110 is different. By allowing the detection device 110 to scan the marker 131 before correcting the posture of the detection device 110, accurate reflectivity change information can be obtained, or the obtained reflectivity change information can be corrected, so as to adjust the correction accuracy.

[0210] In some possible implementation manners, the control device is configured to control the driving assembly 120 to drive the detection device 110 to move according to the reflection signal, including: controlling the driving assembly 120 to drive the detection device 110 to rotate around the first rotation axis, so as to adjust the detection device 110 to the first posture. In this way, the detection device 110 can be corrected around the first rotation axis.

[0211] In some possible implementation manners, the identifier 131 is one, and the identifier 131 is configured to click a target identification point of the display screen 200, and the target identification point includes the first identification point. When the identifier 131 clicks the first identification point, the control driving assembly 120 drives the detection device 110 to rotate around the first rotation axis, so as to adjust the detection device 110 to the first posture. In this way, the detection device 110 can be adjusted from the to-be-adjusted posture to the first posture after the identifier 131 clicks the first identification point, and it is ensured that the detection device 110 can scan the identifier 131 during movement of the detection device 110.

[0212] In some possible implementation manners, the target identification point further includes a second identification point. When the identifier 131 clicks the second identification point, the control driving assembly 120 drives the detection device 110 to rotate around the second rotation axis, so as to adjust the detection device 110 from the first posture to the second posture. In this way, the detection device 110 can be adjusted from the first posture to the second posture after the identifier 131 clicks the first identification point, and the adjustment operation of the detection device 110 rotating around the second rotation axis is realized.

Alternatively, the pen tip part 1311 includes a plurality of sub-body parts, at least one of which is the first part 132, and at least another of which is the second part 133. In addition, the pen tip part can be arranged in a full reflection, a local high reflection, a gradient high reflection, and the like.

[0215] The specific shape of the pen barrel part 1312 is not limited here. For example, the pen barrel part 1312 can be a cylindrical structure or a prism structure.

[0216] In some embodiments, the pen-shaped member can be a stylus, which can also be referred to as a touch pen. The stylus can interact with an electronic device to realize functions such as touch control and handwriting. Of course, in addition to being a stylus, the pen-shaped member can also be a rod-shaped structure similar to a pen.

[0217] In some possible implementation manners, referring to Figure 15 The entire pen tip part 1311 is the first part 132, so that the pen tip part can be arranged in a full reflection.

[0218] Figure 16 Another structural schematic diagram of an identifier provided by an embodiment of the present application, Figure 17Another structural schematic diagram of the identification member provided by the embodiment of the present application is shown in FIG. 6. Figure 18 Another structural schematic diagram of the identification member provided by the embodiment of the present application is shown in FIG. 6.

[0219] In some possible implementation manners, referring to Figure 16 A part of the outer surface of the pen tip part 1311 is the first part 132, and another part is the second part 133. The outer surface of the pen barrel part 1312 is the second part 133. In this way, the outer surface of the pen tip part 1311 is arranged in a local high-reflection manner.

[0220] Alternatively, in some embodiments, referring to Figure 17 or Figure 18 Along the length direction of the pen-shaped member, the pen tip part 1311 includes a plurality of sub-body parts connected in sequence, and the reflectivity of adjacent two sub-body parts to the laser beam is different. The plurality of sub-body parts include at least two first sub-body parts and at least one second sub-body part. The first sub-body part is the first part 132, and the second sub-body part is the second part 133. In this way, the pen tip part 1311 can be arranged in a gradient high-reflection manner.

[0221] The reflectivity of the plurality of first parts 131 in the pen tip part 1311 to the laser beam can be the same or different.

[0222] Figure 19 Another structural schematic diagram of the identification member provided by the embodiment of the present application is shown in FIG. 6. Figure 20 Another structural schematic diagram of the identification member provided by the embodiment of the present application is shown in FIG. 6. Figure 21 Another structural schematic diagram of the identification member provided by the embodiment of the present application is shown in FIG. 6.

[0223] In some possible implementation manners, the identification assembly 130 includes a plurality of identification members 131 arranged at intervals. Each identification member 131 is configured to be fixedly connected to the side of the display screen 200 facing the user. The identification member 131 is fixedly connected to the frame or the display area of the display screen 200.

[0224] In some possible implementation manners, the number of the identification members 131 is a plurality, and each identification member 131 is fixedly connected to the display side of the display screen 200, or in other words, each identification member 131 is configured to be fixedly connected to the side of the display screen 200 facing the user. The identification member 131 is fixedly connected to the frame or the display area of the display screen 200. In this case, referring to Figure 19 The identification member 131 is the first part 132, or referring to Figure 20 or Figure 21The marker 131 is divided into two parts: part 132 and part 133. By fixing the marker 131 to the display screen 200, the user does not need to hold the marker 131 at all times, which reduces the user's labor intensity and improves the user experience. In addition, the reflective side surface can be arranged in a total reflection, partial high reflection, or gradient high reflection manner.

[0225] The specific structure of the sign 131 fixedly connected to the display is not limited here. For example, the sign 131 can be a strip block (such as...). Figure 19 (as shown), cubes, and other structures.

[0226] like Figure 19 As shown, when the identifier 131 is the first part 132, the identifier 131 can be arranged in a fully reversed manner.

[0227] When part of the marker 131 is the first part 132 and part of the marker 131 is the second part 133, the reflective side surface can exhibit localized high reflectivity (e.g., Figure 20 As shown), gradient high inverse (as shown) Figure 21 (as shown in the image) and other arrangements.

[0234] In some possible implementations, the detection device 110 can include a transmitting module and a receiving module. The transmitting module emits a laser beam to the surrounding, the laser beam forms a reflected beam after being irradiated to a target object, and the receiving module receives the reflected beam reflected by the target object. After processing the received reflected beam, information such as the distance, orientation and speed of the target object relative to the detection device 110 is obtained.

The circuit board is electrically connected to a detector and carries the detector.

[0244] Figure 23 The first flowchart of the adjustment method provided in the embodiments of the present application.

[0245] The embodiment of the present application also provides an adjustment method, which is applied to the laser radar in the above embodiment, and the adjustment method can comprise the following steps: Figure 23 The adjustment method can comprise the following steps:

[0246] S1, driving the detection device 110 to move according to a preset trajectory by the driving assembly 120, so as to adjust the detection device 110 to a to-be-adjusted posture.

[0247] Specifically, the driving assembly 120 can be controlled by the control device to drive the detection device 110 to move according to the preset trajectory, so as to adjust the detection device 110 to the to-be-adjusted posture. In addition, by adjusting the detection device 110 to the to-be-adjusted posture, no matter what the current posture of the detection device 110 is, the detection device 110 can be ensured to move according to the preset trajectory, so as to correct the posture of the detection device 110, and achieve the purpose of correcting the position of the laser scanning plane.

[0248] In some possible implementation manners, in response to the adjustment signal, the detection device 110 is driven to move according to the preset trajectory by the driving assembly 120, so as to adjust the detection device 110 to the to-be-adjusted posture.

[0249] The adjustment signal can be a signal generated by the marker 131 itself or a signal generated by other equipment, and the other equipment can be a remote controller, a mobile phone or the like.

[0250] In some possible implementation manners, the detection device 110 is driven to rotate by a certain angle around at least one of the first rotation axis and the second rotation axis by the driving assembly 120, so that the movement trajectory of the detection device 110 is the preset trajectory, and the current posture of the detection device 110 is adjusted to the to-be-adjusted posture.

[0251] The first rotation axis and the second rotation axis intersect and do not coincide, for example, the first rotation axis is perpendicular to the second rotation axis. Of course, the included angle between the first rotation axis and the second rotation axis can also be an acute angle or an obtuse angle, in addition to a right angle.

[0252] In some embodiments, the first rotation axis is parallel to a horizontal plane, and the second rotation axis is perpendicular to the horizontal plane. Specifically, the first rotation axis is parallel to the length direction of the display screen 200, the second rotation axis is parallel to the width direction of the display screen 200, and the horizontal plane is parallel to the thickness direction of the display screen 200. At this time, when the detection device 110 rotates around the first rotation axis, the detection device 110 performs pitching rotation around the first rotation axis. When the detection device 110 rotates around the second rotation axis, the detection device 110 performs horizontal rotation around the second rotation axis.

[0253] Alternatively, in some embodiments, the first rotation axis is perpendicular to the horizontal plane, and the second rotation axis is parallel to the horizontal plane. Specifically, the first rotation axis is parallel to the width direction of the display screen 200, the second rotation axis is parallel to the length direction of the display screen 200, and the horizontal plane is parallel to the thickness direction of the display screen 200. At this time, when the detection device 110 rotates around the first rotation axis, the detection device 110 performs horizontal rotation around the first rotation axis. When the detection device 110 rotates around the second rotation axis, the detection device 110 performs pitching rotation around the second rotation axis.

[0254] In some possible implementations, in the process of controlling the driving assembly 120 to drive the detection device 110 to move according to the preset trajectory, the driving assembly 120 can be controlled to drive the detection device 110 to rotate by a third angle and a fourth angle around the first rotation axis and the second rotation axis respectively, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the driving assembly 120 to drive the detection device 110 to rotate by a certain angle around the two rotation axes, the detection device 110 is adjusted from the current posture to the to-be-adjusted posture.

[0255] In some possible implementations, in the process of controlling the driving assembly 120 to drive the detection device 110 to move according to the preset trajectory, the driving assembly 120 can be controlled to drive the detection device 110 to rotate by a third angle and a fourth angle around the first rotation axis and the second rotation axis respectively, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the driving assembly 120 to drive the detection device 110 to rotate by a certain angle around the two rotation axes, the detection device 110 is adjusted from the current posture to the to-be-adjusted posture.

[0256] In some possible implementations, in the process of controlling the driving assembly 120 to drive the detection device 110 to move according to the preset trajectory, the driving assembly 120 can be controlled to drive the detection device 110 to rotate by a third angle and a fourth angle around the first rotation axis and the second rotation axis respectively, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the driving assembly 120 to drive the detection device 110 to rotate by a certain angle around the two rotation axes, the detection device 110 is adjusted from the current posture to the to-be-adjusted posture.

[0257] Alternatively, in some embodiments, in the process of controlling the driving assembly 120 to drive the detection device 110 to move according to the preset trajectory, the driving assembly 120 can be controlled to drive the detection device 110 to rotate by a third angle and a fourth angle around the first rotation axis and the second rotation axis respectively, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the driving assembly 120 to drive the detection device 110 to rotate by a certain angle around the two rotation axes, the detection device 110 is adjusted from the current posture to the to-be-adjusted posture.

[0258] In some possible implementations, in the process of controlling the driving assembly 120 to drive the detection device 110 to move according to the preset trajectory, the driving assembly 120 can be controlled to drive the detection device 110 to rotate by a third angle and a fourth angle around the first rotation axis and the second rotation axis respectively, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the driving assembly 120 to drive the detection device 110 to rotate by a certain angle around the two rotation axes, the detection device 110 is adjusted from the current posture to the to-be-adjusted posture.

[0259] Or, in some embodiments, when the first rotation axis is parallel to the width direction of the display screen 200 and the second rotation axis is parallel to the length direction of the display screen 200, in the process in which the driving assembly 120 drives the detection device 110 to move along the preset track, the driving assembly 120 can first drive the detection device 110 to rotate horizontally around the first rotation axis, and then drive the detection device 110 to pitch around the second rotation axis.

[0260] Of course, in addition to controlling the detection device 110 to rotate around the first rotation axis and the second rotation axis in the process in which the driving assembly 120 drives the detection device 110 to move along the preset track, in some possible implementation manners, in the process in which the driving assembly 120 drives the detection device 110 to move along the preset track, the driving assembly 120 can also be controlled to drive the detection device 110 to rotate a fifth angle around the first rotation axis or the second rotation axis, so as to adjust the detection device 110 to the to-be-adjusted posture. In this way, by controlling the detection device 110 to rotate the fifth angle around one of the first rotation axis and the second rotation axis, the detection device 110 is adjusted to the to-be-adjusted posture.

[0261] When the detection device 110 rotates the fifth angle around the first rotation axis, the detection device 110 can rotate horizontally around the first rotation axis or pitch around the first rotation axis.

[0262] When the detection device 110 rotates the fifth angle around the second rotation axis, the detection device 110 can rotate horizontally around the second rotation axis or pitch around the second rotation axis.

[0263] Figure 24 A position diagram of a laser beam of the detection device provided in the embodiments of the present application when the detection device is in a to-be-adjusted posture.

[0264] In some possible implementation manners, referring to Figure 24 When the detection device 110 is in the to-be-adjusted posture, the laser beam is arranged on the display side of the display screen 200 of the electronic device and is arranged to be spaced apart from the display screen 200. In this way, the laser scanning surface is arranged on the display side of the display screen 200 and is arranged to be spaced apart from the display screen 200, that is, the laser scanning surface is located in front of the display screen 200, and the position of the laser scanning surface can be adjusted by reducing the distance between the laser scanning surface and the display screen 200, and the difficulty of adjusting the position of the laser scanning surface can be reduced.

[0265] The front of the display screen 200 is taken as a reference object of a user, and a side region of the display screen 200 facing the user is the front, and a side region of the display screen 200 away from the user is the back.

[0266] It should be noted that when the detection device 110 is in the to-be-adjusted posture, the laser scanning surface can hit the display screen 200 in addition to being located in front of the display screen 200 in some embodiments, that is, the display screen 200 can intersect the laser scanning surface.

[0267] S2, control the driving assembly 120 to drive the detection device 110 to move to correct the posture of the detection device 110, wherein the reflection signal is a signal generated by reflection after the laser beam emitted by the detection device 110 irradiates the marker 131.

[0268] Specifically, after the detection device 110 of the laser radar is adjusted to the to-be-adjusted posture, the detection device 110 of the laser radar moves. At the same time, in the process of the movement of the detection device 110, the laser beam emitted by the detection device 110 of the laser radar is reflected by the marker 131 in the marker position to generate a reflection signal that can be received by the detection device 110 of the laser radar. Then, the laser radar controls the driving assembly 120 to drive the detection device 110 to move according to the received reflection signal, so as to correct the posture of the detection device 110, and further correct the position of the laser scanning surface, so as to adjust the distance between the laser scanning surface and the display screen 200.

[0269] It should be noted that the marker position is the position of the marker 131 when the marker 131 clicks the marker point of the display screen 200 or is fixedly connected to the marker point, therefore, the number of marker positions is the same as the number of marker points described above, and the layout of multiple marker positions is the same as the layout of multiple marker points.

[0270] The number of marker positions is not limited here. For example, the multiple marker positions can include a first marker position and a second marker position, and the detection device 110 can sequentially scan the markers 131 in the first marker position and the second marker position. Alternatively, the multiple marker positions can include a first marker position, a second marker position, and a third marker position, and the detection device 110 can sequentially scan the markers 131 in the first marker position, the second marker position, and the third marker position.

[0271] Because the coordinates of the marker points at different positions are different, the specific coordinates of the marker 131 are different when the marker 131 clicks or is fixedly connected to the marker points at different positions, and the reflection signals formed by the reflection of the laser beam by the markers 131 in different marker positions are different. By previously calibrating the reflection signals generated by the reflection of the laser beam by the markers 131 in each marker position, and then processing the reflection signals received by the detection device 110, it can be determined that the detection device 110 scans the marker 131 in which marker position.

[0272] For how to determine that the detection device 110 has scanned the identification member 131, the reflection characteristics of the identification member 131 to the laser beam can be determined, such as when the material of the part of the surface of the identification member 131 is a high-reflection material, the laser beam reflected by the high-reflection material will form a light spot with relatively large brightness. Therefore, by comparing whether the reflection signal received by the detection device 110 in real time is the same as the preset signal, it can be determined whether the detection device 110 scans the identification member 131.

[0273] Exemplarily, the identification member 131 has a high-reflection material, and when the detection device 110 scans the area where the high-reflection material is located to form a reflection signal reflected by the laser beam, it can be determined that the detection device 110 scans the identification member 131.

[0274] When the identification member 131 has a high-reflection material, the arrangement of the high-reflection material can include but is not limited to the full-reflection, partial high-reflection, gradient high-reflection and the like described above. Therefore, in some embodiments, the detection device 110 can be determined to scan the identification member 131 when the detection device 110 scans the high-reflection material for the first time. Or in some embodiments, the detection device 110 can be determined to scan the identification member 131 when the detection device 110 scans the high-reflection material for the second time. Or in some embodiments, the detection device 110 can be determined to scan the identification member 131 when the detection device 110 scans the high-reflection material for the third time.

[0275] In some possible implementations, the reflection signal includes a first reflection signal, and the driving assembly 120 is controlled to drive the movement of the detection device 110 according to the reflection signal, including: the driving assembly 120 is controlled to drive the movement of the detection device 110 according to the first reflection signal.

[0276] Specifically, in the process of driving the movement of the detection device 110 by the driving assembly 120 of the laser radar, the laser beam emitted by the detection device 110 is reflected by the first part 132 of the identification member 131 to generate a first reflection signal that can be received by the detection device 110. The laser radar can control the driving assembly 120 to drive the movement of the detection device 110 according to the first reflection signal, so that the detection device 110 performs corresponding operations.

[0277] Among them, the reflectivity of the first part 132 is higher than that of at least part of the rest of the identification member 131. In addition, the first part 132 can include a high-reflection material, so that the reflectivity of the first part 132 to the laser beam is relatively high.

[0278] In some possible implementations, the reflection signal further includes a second reflection signal, and the adjustment method further includes:

[0279] The driving assembly 120 is controlled to drive the detection device 110 to move according to the first reflection signal and the second reflection signal, and the driving assembly 120 is controlled to drive the detection device 110 to move according to the reflectivity change information. The reflectivity change information is information determined based on the reflectivity change between the first part 132 and the second part 133 of the marker 131.

[0280] In the process of driving the detection device 110 to move by the driving assembly 120 of the laser radar, the laser beam emitted by the detection device 110 is reflected by the first part 132 of the marker 131 to generate a first reflection signal that can be received by the detection device 110. Similarly, in the process of driving the detection device 110 to move by the driving assembly 120 of the laser radar, the laser beam emitted by the detection device 110 is reflected by the second part 133 of the marker 131 to generate a second reflection signal that can be received by the detection device 110, or a second reflection signal that cannot be received by the detection device 110, or a second reflection signal that cannot be generated and received by the detection device 110. After the laser radar receives the first reflection signal and the second reflection signal, the laser radar controls the driving assembly 120 to drive the detection device 110 to move to perform corresponding operations.

[0281] In some embodiments, the laser radar can determine the reflectivity change information according to the received first reflection signal and second reflection signal, and control the driving assembly 120.

[0282] The reflectivity of the first part 132 to the laser beam emitted by the detection device 110 is greater than the reflectivity of the second part 133 to the laser beam emitted by the detection device 110, so that the intensity of the laser beam reflected by the first part 132 to the detection device 110 is greater than the intensity of the laser beam reflected by the second part 133 to the detection device 110.

[0283] In some possible implementations, the driving assembly 120 is controlled to drive the detection device 110 to move according to the reflectivity change information, including:

[0284] When the laser beam emitted by the detection device 110 is scanned from the second part 133 to the first part 132, the driving assembly 120 is controlled to drive the detection device 110 to stop moving according to the reflectivity change information.

[0285] Exemplarily, the reflectivity change information includes information about the change in the intensity of the laser beam received by the detection device 110 due to the reflectivity change.

[0286] In some embodiments, the driving assembly 120 is controlled to drive the detection device 110 to stop moving according to the reflectivity change information, including: driving the detection device 110 to stop moving by the driving assembly 120 when the intensity of the laser beam changes to meet a preset condition.

[0287] In some embodiments, the driving component 120 is controlled to drive the detection device 110 to stop moving when the intensity variation of the laser beam meets a preset condition, including: when the intensity curve of the laser beam appears a peak, the driving component 120 is driven to drive the detection device 110 to stop moving.

[0288] Alternatively, in some embodiments, the driving component 120 is controlled to drive the detection device 110 to stop moving when the intensity variation of the laser beam meets a preset condition, including: when the intensity curve of the laser beam appears a peak and a preset time elapses, the driving component 120 is driven to drive the detection device 110 to stop moving.

[0289] Figure 25 The second flowchart of the adjustment method provided by the embodiments of the present application.

[0290] In some possible implementations, the driving component 120 is controlled to drive the detection device 110 to move according to the reflection signal, referring to Figure 25 , including:

[0291] S201, the driving component 120 is driven to rotate the detection device 110 around the first rotation axis, so as to adjust the detection device 110 to a first attitude.

[0292] After the detection device 110 is adjusted to the to-be-adjusted attitude, the driving component 120 is driven to rotate the detection device 110 around the first rotation axis, so as to adjust the detection device 110 to the first attitude. In the process of rotating the detection device 110 around the first rotation axis, the laser beam emitted by the laser radar is reflected by the identification element 131 to generate a reflection signal. The laser radar controls the driving component to drive the detection device 110 to move around the first rotation axis according to the received reflection signal, so as to adjust the detection device 110 to the first attitude.

[0293] Wherein, the method of controlling the driving component 110 to drive the detection device 110 to move around the first rotation axis according to the reflection signal can refer to the method described in the foregoing.

[0294] In some possible implementations, the step S201 can include:

[0295] The driving component 120 is controlled to drive the detection device 110 in the to-be-adjusted attitude to rotate around the first rotation axis until the reflection signal is a first preset signal, so as to adjust the detection device 110 to the first attitude. The reflection signal being the first preset signal determines that the detection device 110 scans the identification element 131 in the first identification position.

[0296] The first rotation axis can be parallel to the length direction of the display screen 200, or the first rotation axis can be parallel to the width direction of the display screen 200.

[0297] In the process of adjusting the detection device 110 from the to-be-adjusted posture to the first posture, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis, and processes the reflection signal received by the detection device 110 to determine whether the reflection signal is the first preset signal. When the reflection signal is not the first preset signal, the detection device 110 does not scan the identification member 131 in the first identification position, and the driving assembly 120 drives the detection device 110 to continue to rotate around the first rotation axis. When the reflection signal is the first preset signal, it is determined that the detection device 110 scans the identification member 131 in the first identification position, and the driving assembly 120 is controlled to stop driving the detection device 110 to rotate around the first rotation axis, that is, the detection device 110 is controlled to stop continuing to rotate around the first rotation axis while scanning the identification member 131 in the first identification position.

[0298] In some embodiments, the first preset signal can be understood as a signal generated by reflection after the laser beam irradiates a specific region of the identification member 131 in the first identification position. For example, when the identification member 131 is a pen-shaped member, the first preset signal can be a signal generated by reflection after the laser beam irradiates the pen tip 1311. Or, when the identification member 131 is a bar-shaped block or other structure fixedly connected to the display screen 200, the first preset signal can be a signal generated by reflection after the laser beam irradiates a specific region of the reflection side surface of the identification member 131.

[0299] In some embodiments, when the layout of the high-reflection material on the identification member 131 is full reflection or local high-reflection layout, the specific region can be the region where the high-reflection material is located, and the first preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflection material. Therefore, when the detection device 110 scans the high-reflection material, the detection device 110 is controlled to stop rotating around the first rotation axis.

[0300] In other embodiments, when the layout of the high-reflection material on the identification member 131 is gradient high-reflection, the specific region can be one of the regions where the high-reflection materials are located, and the first preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflection material for the Mth time. For example, the first preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflection material for the second time. Wherein, M can be a positive integer, such as 1, 2, 3, etc.

[0301] It should be noted that in step S201, in addition to stopping the rotation of the detection device 110 when the identification member 131 in the first identification position is scanned, in some possible implementation manners, step S201 can include: controlling the driving assembly 120 to drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis until the detection device 110 continues to rotate by a first angle after the reflected signal is the first preset signal, so as to adjust the detection device 110 to the first posture. In this way, the distance between the laser scanning surface and the display screen 200 can be further reduced, and the touch precision can be further improved.

[0302] Specifically, in the process of adjusting the detection device 110 from the to-be-adjusted posture to the first posture, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis, and at the same time, processes the reflected signal received by the detection device 110 and determines whether the reflected signal is the first preset signal. When the reflected signal is not the first preset signal, the detection device 110 does not scan the identification member 131 in the first identification position, and the driving assembly 120 drives the detection device 110 to continue to rotate around the first rotation axis. When the reflected signal is the first preset signal, it is determined that the detection device 110 scans the identification member 131 in the first identification position, and the driving assembly 120 is controlled to drive the detection device 110 to continue to rotate around the first rotation axis by a first angle and then stop, that is, after scanning the identification member 131 in the first identification position, the detection device 110 will continue to rotate around the first rotation axis by a first angle and then stop.

[0303] It can be understood that the rotation direction of the detection device 110 before scanning the identification member 131 in the first identification position is the same as the rotation direction of the detection device 110 after scanning the identification member 131 in the first identification position.

[0304] In some possible implementation manners, when the identification member 131 clicks the first identification point of the display screen, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis, so as to adjust the detection device 110 to the first posture.

[0305] Specifically, the target identification point of the display screen 200 includes the first identification point, and after the first identification point is clicked by the identification member 131, the driving assembly 120 of the laser radar drives the detection device 110 to rotate around the first rotation axis, so as to adjust the detection device 110 to the first posture.

[0306] It should be noted that the target identification point can include a plurality of identification points, and the layout of the plurality of identification points has been described in detail in the foregoing, and thus will not be described in detail here.

[0307] It can be understood that when the identification member 131 does not click the first identification point, the driving assembly 120 of the laser radar does not drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis.

[0308] It should be noted that when the identification member 131 clicks the first identification point, the identification member 131 is in the first identification position. In addition, the specific method of adjusting the detection device 110 from the to-be-adjusted posture to the first posture has been described in detail in the foregoing, and thus will not be described here.

[0309] In some possible implementation manners, the driving assembly 120 is controlled to drive the detection device 110 to move according to the reflection signal, and the reflection signal is generated by reflecting the laser beam emitted by the laser radar through the identification member 131. Figure 25 Further comprising:

[0310] S202, rotating the detection device 110 around the second rotation axis by the driving assembly 120 to adjust the detection device 110 from the first posture to the second posture.

[0311] After the detection device 110 is adjusted to the first posture, the detection device 110 is driven to rotate around the second rotation axis by the driving assembly 120 to adjust the detection device 110 to the second posture. In the process of rotating the detection device 110 around the second rotation axis, the reflection signal is generated by reflecting the laser beam emitted by the laser radar through the identification member 131. The driving assembly 120 is controlled to drive the detection device 110 to move around the second rotation axis according to the received reflection signal, so as to adjust the detection device 110 from the first posture to the first posture.

[0312] In the method, the driving assembly 110 is controlled to drive the detection device 110 to move around the second rotation axis according to the reflection signal, and the method can refer to the method of controlling the driving assembly 110 to drive the detection device 110 to move according to the reflection signal described in the foregoing.

[0313] In some possible implementation manners, the step S202 can include:

[0314] The driving assembly 120 is controlled to drive the detection device 110 in the first posture to rotate around the second rotation axis until the reflection signal is the second preset signal, so as to adjust the detection device 110 to the second posture. The reflection signal being the second preset signal determines that the detection device 110 scans the identification member 131 in the second identification position.

[0315] In the process of adjusting the detection device 110 from the first posture to the second posture, the driving assembly 120 drives the detection device 110 to rotate around the second rotation axis, and processes the reflection signal received by the detection device 110 to determine whether the reflection signal is the second preset signal. When the reflection signal is not the second preset signal, the detection device 110 does not scan the identification member 131 in the second identification position, and the driving assembly 120 drives the detection device 110 to continue rotating around the second rotation axis. When the reflection signal is the second preset signal, it is determined that the detection device 110 scans the identification member 131 in the second identification position, and the driving assembly 120 is controlled to stop driving the detection device 110 to rotate around the second rotation axis, that is, the detection device 110 is controlled to stop rotating around the second rotation axis while scanning the identification member 131 in the second identification position.

[0316] In some embodiments, the second preset signal can be understood as a signal generated by reflection after the laser beam irradiates a specific region of the identification member 131 in the second identification position. For example, when the identification member 131 is a pen-shaped member, the second preset signal can be a signal generated by reflection after the laser beam irradiates the pen tip 1311. Alternatively, when the identification member 131 is a bar-shaped block or other structure fixedly connected to the display screen 200, the second preset signal can be a signal generated by reflection after the laser beam irradiates a specific region of the reflective side surface of the identification member 131.

[0317] In some embodiments, when the layout of the high-reflective material on the identification member 131 is full reflection or local high-reflective layout, the specific region is a region where the high-reflective material is located, and the second preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflective material. Therefore, when the detection device 110 scans the high-reflective material, the detection device 110 is controlled to stop rotating around the second rotation axis.

[0318] In other embodiments, when the layout of the high-reflective material on the identification member 131 is gradient high-reflective, the specific region is one of a plurality of regions where the high-reflective material is located, and the second preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflective material for the Mth time. For example, the second preset signal can be a signal generated by reflection after the laser beam irradiates the high-reflective material for the second time.

[0319] It should be noted that in step S202, in addition to stopping rotating when the detection device 110 scans the identification member 131 in the second identification position, in some possible implementation manners, step S202 can include:

[0320] The control driving assembly 120 drives the detection device 110 in the first posture to rotate around the second rotation axis until the reflected signal is the second preset signal, and then drives the detection device 110 to continue rotating by the second angle to adjust the detection device 110 to the second posture. In this way, the distance between the laser scanning surface and the display screen 200 can be further reduced, and the touch precision can be further improved.

[0321] Specifically, in the process of adjusting the detection device 110 from the first posture to the second posture, the driving assembly 120 drives the detection device 110 to rotate around the second rotation axis, and processes the reflected signal received by the detection device 110 and determines whether the reflected signal is the second preset signal. When the reflected signal is not the second preset signal, the detection device 110 does not scan the identification member 131 in the second identification position, and the driving assembly 120 drives the detection device 110 to continue rotating around the second rotation axis. When the reflected signal is the second preset signal, it is determined that the detection device 110 scans the identification member 131 in the second identification position, and the driving assembly 120 is controlled to drive the detection device 110 to continue rotating around the second rotation axis by the second angle and then stop, that is, the detection device 110 will continue to rotate around the second rotation axis by the second angle after scanning the identification member 131 in the second identification position and then stop.

[0322] It can be understood that the rotation direction of the detection device 110 before scanning the identification member 131 in the second identification position is the same as the rotation direction of the detection device 110 after scanning the identification member 131 in the second identification position.

[0323] In summary, by executing step S201 first and then executing step S202, the posture of the detection device 110 can be adjusted, so that the position of the laser scanning surface can be adjusted, and then the distance between the laser scanning surface and the display screen 200 can be adjusted.

[0324] It should be noted that, in addition to adjusting the position of the laser scanning surface by the identification members 131 in the two identification positions cooperating with the detection device 110, in some embodiments, after the detection device 110 scans the identification members 131 in the first identification position and the second identification position in turn, the detection device 110 can continue to scan the identification members 131 in the third identification position, the fourth identification position, and identification members 131 in other identification positions.

[0325] In the foregoing description, steps S201 and S202 each have two schemes, therefore, the two schemes of step S301 and the two schemes of step S302 can be freely combined, which will be introduced by way of example as follows:

[0326] In some embodiments, the driving assembly 120 can first drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis, and the detection device 110 stops rotating after scanning the marker 131 in the first marker position, so as to adjust the detection device 110 to the first posture. After adjusting the detection device 110 to the first posture, the driving assembly 120 drives the detection device 110 in the first posture to rotate around the second rotation axis, and the detection device 110 stops rotating after scanning the marker 131 in the second marker position, so as to adjust the detection device 110 to the second posture.

[0327] Alternatively, in some embodiments, the driving assembly 120 can first drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis, and the detection device 110 continues to rotate by a first angle around the first rotation axis after scanning the marker 131 in the first marker position, and then stops, so as to adjust the detection device 110 to the first posture. After adjusting the detection device 110 to the first posture, the driving assembly 120 drives the detection device 110 in the first posture to rotate around the second rotation axis, and the detection device 110 continues to rotate by a second angle around the second rotation axis after scanning the marker 131 in the second marker position, and then stops, so as to adjust the detection device 110 to the second posture.

[0328] Alternatively, in some embodiments, the driving assembly 120 can first drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis, and the detection device 110 stops rotating after scanning the marker 131 in the first marker position, so as to adjust the detection device 110 to the first posture. After adjusting the detection device 110 to the first posture, the driving assembly 120 drives the detection device 110 in the first posture to rotate around the second rotation axis, and the detection device 110 continues to rotate by a second angle around the second rotation axis after scanning the marker 131 in the second marker position, and then stops, so as to adjust the detection device 110 to the second posture.

[0329] Alternatively, in some embodiments, the driving assembly 120 can first drive the detection device 110 in the to-be-adjusted posture to rotate around the first rotation axis, and the detection device 110 continues to rotate by a first angle around the first rotation axis after scanning the marker 131 in the first marker position, and then stops, so as to adjust the detection device 110 to the first posture. After adjusting the detection device 110 to the first posture, the driving assembly 120 drives the detection device 110 in the first posture to rotate around the second rotation axis, and the detection device 110 stops rotating after scanning the marker 131 in the second marker position, so as to adjust the detection device 110 to the second posture.

[0330] In some possible implementation manners, in the process of adjusting the detection device 110 from the to-be-adjusted posture to the second posture, the detection device 110 is rotated about the first rotation axis in the pitching rotation, and the detection device 110 is rotated about the second rotation axis in the horizontal rotation.

[0331] Alternatively, in some possible implementation manners, in the process of adjusting the detection device 110 from the to-be-adjusted posture to the second posture, the detection device 110 is rotated about the first rotation axis in the horizontal rotation, and the detection device 110 is rotated about the second rotation axis in the horizontal rotation.

[0332] In some possible implementation manners, when the detection device 110 is in the to-be-adjusted posture and the laser beam is located on the display side of the display screen 200 and spaced apart from the display screen 200, in the process of adjusting the detection device 110 from the to-be-adjusted posture to the first posture, the detection device 110 is rotated about the first rotation axis in the pitching rotation, so that the spacing between the laser beam and the display surface of the display screen 200 gradually decreases. In this way, the difficulty of adjusting the laser scanning surface can be reduced.

[0333] In some possible implementation manners, when the identification member 131 clicks the second identification point of the display screen, the driving assembly 120 drives the detection device 110 to rotate about the second rotation axis, so as to adjust the detection device 110 from the first posture to the second posture.

[0334] Specifically, after the identification member 131 clicks the second identification point, the driving assembly 120 of the laser radar drives the detection device 110 to rotate about the second rotation axis, so as to adjust the detection device 110 to the second posture.

[0335] It can be understood that, when the identification member 131 does not click the second identification point, the driving assembly 120 of the laser radar does not drive the detection device 110 in the to-be-adjusted posture to rotate about the second rotation axis.

[0336] It should be noted that, when the identification member 131 clicks the second identification point, the identification member 131 is in the second identification position. In addition, the specific method of adjusting the detection device 110 from the first posture to the second posture has been described in detail in the foregoing, and thus will not be described here again.

[0337] It should be noted that, when the identification member 131 is fixedly connected to the display screen 200, the identification member 131 is always in contact with the target identification point of the display screen, and at this time, it is not necessary to judge whether the identification member 131 is in contact with the identification point. Therefore, when the identification member 131 is fixedly connected to the display screen 200, the adjustment method provided in this embodiment does not need to control the driving assembly 120 to drive the detection device 110 to move to correct the posture of the detection device 110 after the identification member 131 clicks the target identification point according to the reflected signal.

[0338] In some possible implementations, before the driving assembly 120 is controlled according to the reflection signal, the adjusting method further includes the following steps:

[0339] S3, driving the detection device 110 to move away from the display screen 200 by the driving assembly 120, and / or driving the detection device 110 to move towards the display screen 200 by the driving assembly 120, to obtain reflectivity change information. The reflectivity change information is information determined based on a reflectivity change between the first part 132 and the second part 133 of the identification member 131.

[0340] Because different identification members 131 have different sizes, the reflectivity change information of the identification member 131 scanned by the detection device 110 is different. By allowing the detection device 110 to scan the identification member 131 before the posture of the detection device 110 is corrected, accurate reflectivity change information can be obtained or the obtained reflectivity change information can be corrected to adjust the correction accuracy.

[0341] It should be noted that the step S5 is performed before the step S1.

[0342] The adjusting method provided by the embodiment of the application will be described below in combination with a specific implementation.

[0343] In one possible implementation, the structure of the laser radar system 100 is as shown in Figure 4 At this time, the identification member 131 and the display screen 200 are in a split structure, and the identification member 131 is used to click a target identification point of the display screen 200. The target identification point includes a first identification point and a second identification point. Referring to the figure, the first identification point and the detection device 110 are arranged side by side and spaced apart along the width direction of the display screen 200, and are close to the bottom side of the display screen 200. The second identification point and the first identification point are arranged side by side and spaced apart along the length direction of the display screen 200, and the second identification point is located on the left side of the first identification point along the length direction of the display screen 200.

[0344] Figure 26 A flow chart of one specific implementation of the adjusting method provided by the embodiment of the application.

[0345] For the laser radar system 100 as shown in Figure 4 One specific implementation of the adjusting method provided by the embodiment of the application can be as follows for the laser radar system 100 as shown in

[0346] First, referring to Figure 26, after the identification member 131 clicks the first identification point, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis and in the first rotation direction by a third angle, so that the laser beam moves upward by a first distance, to make the laser beam be located on the display side of the display screen 200 and be spaced apart from the display screen 200. Then, the driving assembly 120 drives the detection device 110 to rotate around the second rotation axis and in the second rotation direction by a fourth angle, so that the laser beam moves rightward by a second distance, to adjust the detection device 110 to the to-be-adjusted posture. Wherein, the detection device 110 rotates around the first rotation axis to pitch, and the detection device 110 rotates around the second rotation axis to horizontally rotate.

[0347] Then, referring to Figure 26 After the detection device 110 is adjusted to the to-be-adjusted posture, the driving assembly 120 drives the detection device 110 to rotate around the first rotation axis and in the third rotation direction, so that the laser beam moves downward. In this process, whether the detection device 110 scans the identification member 131 in the first identification position is determined according to the reflection signal received by the detection device 110. The position of the identification member 131 when it clicks the first identification point is the first identification position. When the detection device 110 does not scan the identification member 131 in the first identification position, the driving assembly 120 continues to drive the detection device 110 to rotate around the first rotation axis and in the third rotation direction. When the reflection signal is the first preset signal, it is determined that the detection device 110 scans the identification member 131 in the first identification position, and the driving assembly 120 is controlled to move, so that the detection device 110 stops continuing to rotate in the third rotation direction, to adjust the detection device 110 to the first posture. Wherein, the first rotation direction and the third rotation direction are opposite directions.

[0348] Finally, referring to Figure 26 After the detection device 110 is adjusted to the first posture, if the identification member 131 clicks the second identification point, the driving assembly 120 is controlled to drive the detection device 110 to rotate around the second rotation axis and in the fourth rotation direction, so that the laser beam moves leftward. In this process, whether the detection device 110 scans the identification member 131 in the second identification position is determined according to the reflection signal received by the detection device 110. The position of the identification member 131 when it clicks the second identification point is the second identification position. When the detection device 110 does not scan the identification member 131 in the second identification position, the driving assembly 120 continues to drive the detection device 110 to rotate around the second rotation axis and in the fourth rotation direction. When the reflection signal is the second preset signal, it is determined that the detection device 110 scans the identification member 131 in the second identification position, and the driving assembly 120 is controlled to move, so that the detection device 110 stops continuing to rotate in the fourth rotation direction, to adjust the detection device 110 to the second posture, to achieve the purpose of correcting the position of the laser scanning surface. Wherein, the second rotation direction and the fourth rotation direction are opposite directions.

[0351] First, see Figure 27 After the first marker point is clicked by the marker 131, the drive assembly 120 first drives the detection device 110 to rotate around the first rotation axis and in the first rotation direction by a third angle, causing the laser beam to move upward by a first distance, so that the laser beam is located on the display side of the display screen 200 and spaced apart from the display screen 200. Then, the drive assembly 120 drives the detection device 110 to rotate around the second rotation axis and in the second rotation direction by a fourth angle, causing the laser beam to move to the right by a second distance, so as to adjust the detection device 110 to the posture to be adjusted. Among them, the detection device 110 performs pitch rotation around the first rotation axis and horizontal rotation around the second rotation axis.

[0352] Next, see Figure 27 After adjusting the detection device 110 to the desired orientation, the drive assembly 120 drives the detection device 110 to rotate around the first rotation axis and along the third rotation direction, causing the laser beam to move downwards. During this process, the detection device 110 determines whether it has scanned the marker 131 at the first marker position based on the reflected signal received by the detection device 110. The position of the marker 131 when it clicks the first marker point is the first marker position. When the detection device 110 does not scan the marker 131 at the first marker position, the drive assembly 120 continues to drive the detection device 110 to rotate around the first rotation axis and along the third rotation direction. When the reflected signal is a first preset signal, it is determined that the detection device 110 has scanned the marker 131 at the first marker position. At the same time, after the reflected signal is the first preset signal, the drive assembly 120 controls the detection device 110 to continue rotating along the third rotation direction by a first angle before stopping, so as to adjust the detection device 110 to the first orientation. The first rotation direction and the third rotation direction are opposite directions.

[0353] Finally, see Figure 27After the probe device 110 is adjusted to the first posture, if the identification member 131 clicks the second identification point, the control driving assembly 120 drives the probe device 110 to rotate around the second rotation axis and in the fourth rotation direction, so that the laser beam moves to the left. In this process, it is determined according to the reflection signal received by the probe device 110 whether the probe device 110 scans the identification member 131 in the second identification position. The position of the identification member 131 when it clicks the second identification point is the second identification position. When the probe device 110 does not scan the identification member 131 in the second identification position, the control driving assembly 120 continues to drive the probe device 110 to rotate around the second rotation axis and in the fourth rotation direction. When the reflection signal is the second preset signal, it is determined that the probe device 110 scans the identification member 131 in the second identification position. At the same time, after the reflection signal is the second preset signal, the control driving assembly 120 drives the probe device 110 to continue to rotate in the fourth rotation direction by a second angle and then stop, so as to adjust the probe device 110 to the second posture, thereby achieving the purpose of correcting the position of the laser scanning plane. The second rotation direction and the fourth rotation direction are opposite directions.

[0354] In a possible implementation, the structure of the laser radar system 100 is as shown in Figure 5 At this time, the identification member 131 and the display screen 200 are in a split structure, and the identification member 131 is used to click the target identification point of the display screen 200. The target identification point includes the first identification point and the second identification point. Referring to the drawings, the first identification point and the probe device 110 are arranged side by side and spaced apart in the width direction of the display screen 200, and are close to the bottom side of the display screen 200. The second identification point and the first identification point are arranged side by side and spaced apart in the length direction of the display screen 200, and the second identification point is located to the right of the first identification point in the length direction of the display screen 200.

Then, the driving assembly 120 drives the detection device 110 to rotate around the second rotation axis and in the fourth rotation direction by a fourth angle, so that the laser beam moves leftward by a second distance, to adjust the detection device 110 to the to-be-adjusted posture. Wherein, the detection device 110 rotates around the first rotation axis to pitch, and the detection device 110 rotates around the second rotation axis to horizontally rotate.

In this process, whether the detection device 110 scans the identification member 131 in the first identification position is determined according to the reflection signal received by the detection device 110. The position of the identification member 131 when it clicks the first identification point is the first identification position. When the detection device 110 does not scan the identification member 131 in the first identification position, the driving assembly 120 continues to drive the detection device 110 to rotate around the first rotation axis and in the third rotation direction. When the reflection signal is the first preset signal, it is determined that the detection device 110 scans the identification member 131 in the first identification position, and the driving assembly 120 is controlled to move, so that the detection device 110 stops continuing to rotate in the third rotation direction, to adjust the detection device 110 to the first posture. Wherein, the first rotation direction and the third rotation direction are opposite directions.

In this process, whether the detection device 110 scans the identification member 131 in the second identification position is determined according to the reflection signal received by the detection device 110. The position of the identification member 131 when it clicks the second identification point is the second identification position. When the detection device 110 does not scan the identification member 131 in the second identification position, the driving assembly 120 continues to drive the detection device 110 to rotate around the second rotation axis and in the second rotation direction. When the reflection signal is the second preset signal, it is determined that the detection device 110 scans the identification member 131 in the second identification position, and the driving assembly 120 is controlled to move, so that the detection device 110 stops continuing to rotate in the second rotation direction, to adjust the detection device 110 to the second posture, to achieve the purpose of correcting the position of the laser scanning surface. Wherein, the second rotation direction and the fourth rotation direction are opposite directions.

Then, the driving assembly 120 drives the detection device 110 to rotate around the second rotation axis and in the fourth rotation direction by a fourth angle, so that the laser beam moves leftward by a second distance, so as to adjust the detection device 110 to the to-be-adjusted posture. Wherein, the detection device 110 rotates around the first rotation axis for pitch rotation, and the detection device 110 rotates around the second rotation axis for horizontal rotation.

In this process, it is determined whether the detection device 110 scans the identification member 131 in the first identification position according to the reflection signal received by the detection device 110. When the identification member 131 clicks the first identification point, the position thereof is the first identification position. When the detection device 110 does not scan the identification member 131 in the first identification position, the driving assembly 120 continues to drive the detection device 110 to rotate around the first rotation axis and in the third rotation direction. When the reflection signal is the first preset signal, it is determined that the detection device 110 scans the identification member 131 in the first identification position. At the same time, after the reflection signal is the first preset signal, the driving assembly 120 is controlled to drive the detection device 110 to continue rotating around the first rotation axis by a first angle in the third rotation direction and then stop, so as to adjust the detection device 110 to the first posture. Wherein, the first rotation direction and the third rotation direction are opposite directions.

[0364] Finally, referring to FIG. 1, the adjustment method provided by the embodiments of the present application can be as follows: Figure 29 ​After the probe device 110 is adjusted to the first posture, if the identification member 131 clicks the second identification point, the control driving assembly 120 drives the probe device 110 to rotate around the second rotation axis and in the second rotation direction, so that the laser beam moves to the right. In this process, it is determined according to the reflection signal received by the probe device 110 whether the probe device 110 scans the identification member 131 in the second identification position. When the identification member 131 clicks the second identification point, the position where it is located is the second identification position. When the probe device 110 does not scan the identification member 131 in the second identification position, the control driving assembly 120 continues to drive the probe device 110 to rotate around the second rotation axis and in the second rotation direction. When the reflection signal is the second preset signal, it is determined that the probe device 110 scans the identification member 131 in the second identification position. At the same time, after the reflection signal is the second preset signal, the control driving assembly 120 drives the probe device 110 to continue to rotate in the second rotation direction by a second angle and then stop, so as to adjust the probe device 110 to the second posture, thereby achieving the purpose of correcting the position of the laser scanning surface. The second rotation direction and the fourth rotation direction are opposite directions.
