Since the distance and direction between the first preset target and the second preset target are the same as the distance and direction between the exit point of the indicating light beam and the sighting device, the indicating light beam is aligned with the first preset target, the boresight cursor is aligned with the second preset target, the indicating light beam is parallel to the visual field center line identified by the boresight cursor, the indicating light beam is parallel to the ranging laser beam, the ranging laser beam is parallel to the visual field center line identified by the boresight cursor when the indicating light beam is parallel to the visual field center line identified by the boresight cursor, and thus the calibration of the ranging laser and the sighting device is completed. It can be seen that, by aligning the indicating light beam and the boresight cursor with the first preset target and the second preset target respectively, the calibration of the ranging laser is completed, and the user can calibrate the ranging laser by himself.

Description

Technical Field

[0001] This application relates to the field of laser rangefinder calibration technology, and in particular to a laser rangefinder calibration method, storage medium, and laser-assisted sight device. Background Technology

[0002] Sighting devices have wide applications across various industries. For example, rangefinders, telescopes, and some gaming devices are all equipped with sights to observe the position of targets. When using a sight to observe the position of a target, it is usually necessary to determine the distance from the target to the sight to obtain complete target position information. In order to accurately measure the target distance, sights are usually equipped with rangefinding modules such as laser rangefinders.

[0003] Due to mechanical errors during installation, the sight and laser rangefinder module typically require calibration after installation. Calibration involves ensuring that the target measured by the laser rangefinder and the target position seen by the user through the sight are aligned. In practical applications, the size of the observed target is usually much larger than the distance between the laser rangefinder module and the sight. Therefore, it can be assumed that if the rangefinder laser beam emitted by the laser rangefinder module is parallel to the field of view axis of the sight, the target measured by the laser rangefinder and the target position seen by the user through the sight will be aligned. Thus, in practical applications, calibration of the laser rangefinder module usually involves adjusting the rangefinder laser beam emitted by the laser rangefinder module to be parallel to the field of view axis of the sight.

[0004] However, laser rangefinders typically use laser beams with a wavelength of 905nm, while the human eye can only see light with wavelengths between 390nm and 760nm. Therefore, users cannot calibrate the rangefinder and laser rangefinder themselves after installing the rangefinder module and sight. Summary of the Invention

[0005] The purpose of this application is to provide a laser ranging calibration method, a storage medium, and a laser-assisted sight device, so that users can calibrate laser ranging equipment and sights themselves. The specific technical solution is as follows:

[0006] In a first aspect of this application, a laser ranging calibration method is provided, the method comprising:

[0007] A pointer beam is emitted, which is aligned with a first preset target position on a first target; the pointer beam is parallel to the ranging laser beam.

[0008] The aiming device acquires an image of the indicator beam aligned with the first preset target position of the first target;

[0009] Adjust the crosshair cursor in the image to align with the second preset target position of the first target, wherein the distance between the second preset target position and the first preset target position is a first distance, the first distance is the distance between the aiming device and the emission point of the indicator beam, and the direction between the second preset target position and the first preset target position is the same as the direction between the aiming device and the emission point of the indicator beam.

[0010] In one possible implementation, the indicating beam and the ranging laser beam are made parallel beforehand by the following steps:

[0011] A ranging laser beam is emitted, and the ranging laser beam is aligned with a third preset target position of the second target;

[0012] The indicator beam is adjusted to a fourth preset target position aligned with the second target. The distance between the fourth preset target position and the third preset target position is the second distance, which is the distance between the emission point of the indicator beam and the emission point of the ranging laser beam. The direction between the third preset target position and the fourth preset target position is the same as the direction between the emission point of the ranging laser beam and the emission point of the indicator beam.

[0013] In one possible implementation, the second target is pre-set via the following steps:

[0014] Set a third preset target position at any location on the second target;

[0015] Determine the second distance between the exit point of the indicator beam and the exit point of the ranging laser beam;

[0016] A fourth preset target is set at a position on the second target at a distance equal to the second distance from the third preset target.

[0017] In one possible implementation, the method further includes:

[0018] Displays an image of the indicator beam aligned with the first preset target position of the first target;

[0019] Adjusting the crosshair cursor in the image to align with the second preset target position of the first target includes:

[0020] In response to the crosshair adjustment command, the crosshair in the image is adjusted to a second preset target position aligned with the first target.

[0021] In one possible implementation, before acquiring an image of the first preset target position where the guiding beam is aligned with the first target via the aiming device, the method further includes:

[0022] The position and orientation of the fixed sight device.

[0023] This application also provides a laser-assisted sight device, the device comprising:

[0024] A transmitting module is used to emit an indicator beam, which is aligned with a first preset target position of a first target; the indicator beam is parallel to the ranging laser beam.

[0025] The acquisition module is used to acquire an image of the first preset target position where the indicator beam is aligned with the first target through the aiming device;

[0026] An adjustment module is used to adjust the crosshair cursor in the image to a second preset target position aligned with the first target, wherein the distance between the second preset target position and the first preset target position is a first distance, the first distance is the distance between the aiming device and the emission point of the indicator beam in a first direction, and the first direction is the direction in which the second preset target position is located relative to the first preset target position.

[0027] In one possible embodiment, the transmitting module includes: a laser ranging device, the laser ranging device comprising:

[0028] An indicator beam emitting assembly for emitting the indicator beam;

[0029] A ranging laser beam emitting assembly for emitting the ranging laser beam.

[0030] In one possible embodiment, the laser rangefinder further includes an adapter for mechanical connection with a sight device.

[0031] In one possible embodiment, the laser ranging device further includes a first communication module, and the aiming device further includes a second communication module;

[0032] The first communication module is used to establish a communication connection with the second communication module of the sight device.

[0033] This application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, performs any of the laser ranging calibration method steps described above.

[0034] Beneficial effects of the embodiments in this application:

[0035] In this embodiment, since the distance and direction between the first and second preset target positions are the same as the distance and direction between the indicator beam emission point and the aiming device, the indicator beam is aligned with the first preset target position, and the crosshair is aligned with the second preset target position. This ensures that the indicator beam is parallel to the center line of the field of view marked by the crosshair, and that the indicator beam is parallel to the rangefinding laser beam. Therefore, when the indicator beam is parallel to the center line of the field of view marked by the crosshair, the rangefinding laser beam is also parallel to the center line of the field of view marked by the crosshair, thus completing the calibration of the rangefinding laser and the aiming device. It is evident that by applying this embodiment, the rangefinding laser can be calibrated by aligning the indicator beam and the crosshair with the first and second preset target positions respectively, enabling the user to calibrate the rangefinding laser independently.

[0036] Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0051] To enable users to self-calibrate laser rangefinders, this application provides a laser rangefinder calibration method, a storage medium, and a laser-assisted sight device. The laser rangefinder calibration method provided in this application will first be described by way of example.

[0052] like Figure 1 As shown, Figure 1 A flowchart of the laser ranging calibration method provided in this application may include the following steps:

[0053] Step S101: Emit an indicator beam, which is aligned with the first preset target position of the first target; the indicator beam and the ranging laser beam are parallel to each other;

[0054] Step S102: Acquire an image of the first preset target position where the indicator beam is aligned with the first target using a sighting device;

[0055] Step S103: Adjust the crosshair cursor in the image to a second preset target position aligned with the first target, wherein the distance between the second preset target position and the first preset target position is a first distance, the first distance is the distance between the aiming device and the emission point of the indicator beam, and the direction between the second preset target position and the first preset target position is the same as the direction between the aiming device and the emission point of the indicator beam.

[0056] In this embodiment, since the distance and direction between the first and second preset target positions are the same as the distance and direction between the indicator beam emission point and the aiming device, the indicator beam is aligned with the first preset target position, and the crosshair is aligned with the second preset target position. This ensures that the indicator beam is parallel to the center line of the field of view marked by the crosshair, and that the indicator beam is parallel to the rangefinding laser beam. Therefore, when the indicator beam is parallel to the center line of the field of view marked by the crosshair, the rangefinding laser beam is also parallel to the center line of the field of view marked by the crosshair, thus completing the calibration of the rangefinding laser and the aiming device. It is evident that by applying this embodiment, the rangefinding laser can be calibrated by aligning the indicator beam and the crosshair with the first and second preset target positions respectively, enabling the user to calibrate the rangefinding laser independently.

[0057] The aforementioned indicator beam is visible light and can be any laser beam with a wavelength within the visible light spectrum. This indicator beam can be emitted by the indicator beam emitting component of a laser ranging device. Specifically, the indicator beam emitting component is a laser emitter.

[0058] The aforementioned laser rangefinder can be externally connected to a sight device via an adapter. This sight device can be a telescope, certain gaming devices, etc. The adapter can be a clamp, clip, etc., and the specific choice can be made according to actual needs; this application does not impose any specific limitations. Of course, the aforementioned laser rangefinder can also be integrated into the sight device; this application does not impose any specific limitations in this regard.

[0059] The aforementioned laser ranging device may further include a ranging laser beam emitting component for emitting a ranging laser beam. This ranging laser beam emitting component is also a laser emitter. The ranging laser beam is invisible to the human eye, typically a laser with a wavelength of 905 nm, and is used to measure distance.

[0060] like Figure 2 As shown, Figure 2 This is a schematic diagram of a sight device provided in this application. The sight device is externally connected to a laser rangefinder, which can emit parallel indicator beams and rangefinder laser beams.

[0061] The aforementioned indicator beam and ranging laser beam have been calibrated to be parallel during the production process of the laser ranging equipment. Therefore, when calibrating the ranging laser, the user only needs to calibrate the indicator beam and the aiming device so that the indicator beam is parallel to the center line of the user's field of view of the target observed through the aiming device. This will achieve the calibration of the ranging laser, ensuring that the ranging laser beam is parallel to the center line of the user's field of view of the target observed through the aiming device.

[0062] As described above, the laser rangefinder can be connected to or integrated into the aiming device via an adapter. This means the laser rangefinder and the aiming device are rigidly connected, and their relative positions cannot be changed. Therefore, the pointer beam and the aiming device cannot be calibrated by adjusting a mechanical mechanism. Thus, in this embodiment, calibration can be performed by adjusting the position of the positioning cursor in the image using software.

[0063] In this embodiment, laser rangefinding calibration can begin after both the sight device and the laser rangefinder device are detected to be turned on, i.e., steps S101-S103 are executed. If the laser rangefinder device is integrated into the sight device, steps S101-S103 can be executed after the sight device is detected to be turned on.

[0064] The laser ranging calibration method provided in this application will be illustrated below using the aforementioned laser ranging device connected to an external sight as an example:

[0065] In step S101, once both the aiming device and the rangefinding laser device are detected to be turned on, the indicator beam emitting component can be controlled to emit an indicator beam, aligning the indicator beam with a first preset target position on the first target. The first preset target position can be marked with graphics such as black dots or crosses. In one specific implementation, the user can manually turn on the laser rangefinding device, causing the indicator beam emitting component to start operating and emitting the indicator beam. Furthermore, the user can adjust the attitude of the aiming device to ensure the indicator beam hits the first preset target position on the first target. The position of the first preset target position can be preset according to actual needs.

[0066] After performing step S101, an image of the first preset target position of the first target aligned with the indicator beam can be acquired through the aiming device. For example, after performing step S101 and aligning the first indicator beam with the first preset target position of the first target, the user can manually trigger the acquisition module of the aiming device to acquire an image of the first target observed through the lens of the aiming device.

[0067] As another specific implementation, the above-mentioned aiming device may further include: a photosensitive element, which, when the photosensitive element detects laser irradiation at the first preset target position of the first target, triggers the acquisition module of the aiming device to acquire an image of the indicator beam aligned with the first preset target position of the first target.

[0068] The aforementioned aiming device is equipped with a crosshair cursor, which can be moved freely within the image acquired by the acquisition module. After acquiring the image of the first target, the crosshair cursor can be adjusted to align with a second preset target position. This second preset target position can also be marked with a black dot, crosshair, or similar marker. The markings for the first and second preset target positions can be the same or different. In one specific embodiment, the crosshair cursor is an adjustable photosensitive element within the aiming device. This adjustable photosensitive element can be moved freely within the image of the first target, and stops moving when it detects the second preset target position marker in the image.

[0069] The distance between the second preset target and the first preset target is the first distance, which is the distance between the aiming device and the emission point of the indicator beam. The direction between the second preset target and the first preset target is the same as the direction between the aiming device and the emission point of the indicator beam.

[0070] As described above, the laser rangefinding calibration method provided in this application aligns the indicator beam with the center line of the field of view marked by the crosshair cursor, thereby ensuring that the rangefinding laser beam is also parallel to the center line of the field of view marked by the crosshair cursor. Therefore, when setting the first preset target position and the second preset target position on the first target, it is necessary to ensure that when the indicator beam is aligned with the first preset target position and the crosshair cursor is aligned with the second preset target position, the indicator beam and the crosshair beam are parallel to each other. Therefore, the relative positions of the first preset target position and the second preset target position are the same as the relative positions between the indicator beam emission point and the sight lens.

[0071] The relative position between the indicator beam emission point and the sight lens refers to the distance and direction between the projection of the indicator beam emission point onto the first target and the projection of the sight lens onto the first target. In actual products, the indicator beam typically emerges from a lens with a spherical or ellipsoidal shape (hereinafter referred to as the indicator beam emission lens). Compared to the installation distance between the laser rangefinder and the sight, the size of the indicator beam emission lens is usually small; that is, the size of the indicator beam emission lens is negligible compared to the installation distance between the laser rangefinder and the sight. Therefore, the indicator beam emission point can be the center point of the indicator beam emission lens or any point on the indicator beam emission lens. The projection of the sight lens onto the first target can be the projection of any point within the sight lens onto the first target.

[0072] In one possible embodiment, before performing step S102, the position of the aiming device can be fixed to make the calibration result more accurate. As a specific implementation, when calibrating the rangefinder laser, the aiming device with the laser rangefinder mounted can be placed on a tripod, and the position of the aiming device can be adjusted by adjusting the tripod knob, so that the indicator beam hits the first preset target position of the first target, and the position of the aiming device can be fixed by fixing the tripod knob.

[0073] In one possible embodiment, the aforementioned aiming device may further include a display screen, which may be an OLED (Organic Light-Emitting Diode) screen or an LCD (Liquid Crystal Display) screen, etc. The display screen may display a crosshair cursor, which can be moved to any position on the screen.

[0074] The aforementioned sight device can default to displaying a calibration interface on the screen upon initial use, which includes a movable positioning cursor. Alternatively, the screen can default to displaying an observation interface, also displaying the positioning cursor and calibration interface options. Users can access the calibration interface by clicking on a calibration interface option on the screen, such as the "Calibration" icon, to begin calibrating the laser rangefinder and sight device, executing steps S101-S103 as described above.

[0075] In one possible embodiment, the above method may further include:

[0076] The image shows the first preset target position of the indicator beam aligned with the first target.

[0077] Step S102 above, adjusting the crosshair cursor in the image to a second preset target position aligned with the first target, may include:

[0078] In response to the crosshair adjustment command, the crosshair in the image is adjusted to a second preset target position aligned with the first target.

[0079] In this step, the user can adjust the positioning cursor displayed on the calibration interface by dragging, clicking, etc., so that the positioning cursor is aligned with the second preset target position of the first target.

[0080] In this embodiment of the application, the above-mentioned sight device may further include a positioning cursor adjustment button. The positioning cursor adjustment button may be set on the surface of the sight device. For example, buttons may be set for the horizontal direction and the vertical direction respectively. The user can use the above-mentioned button to adjust the position of the positioning cursor in the horizontal direction or the position in the vertical direction, so that the positioning cursor is positioned at the second preset target position of the first target.

[0081] like Figure 3 As shown, Figure 3 This illustration shows a calibration interface provided in an embodiment of this application. Users can adjust the position of the positioning cursor in the horizontal and vertical directions by selecting "horizontal direction" and "vertical direction," respectively.

[0082] In practical use of laser rangefinders, it is usually necessary to display the data measured by the laser rangefinder on devices such as sights or computers. Users can then obtain the position information of the target measured by the laser rangefinder through the sight or computer for further processing. Therefore, in one embodiment of this application, the aforementioned laser rangefinder may further include:

[0083] The first communication module is used to connect the laser ranging device to other devices for communication.

[0084] The aforementioned first communication module can be a Bluetooth communication module, an NFC (Near Field Communication) communication module, or something similar. The laser ranging device can communicate and connect with other devices through this first communication ranging module and transmit data accordingly. This allows the target location information to be displayed intuitively to the user, improving the user experience.

[0085] The specific type of the first communication module can be selected according to actual needs, as long as it enables communication between the laser rangefinder and the device it is applied to. The laser rangefinder is applied to devices including sights, computers, etc., and this application does not specifically limit this.

[0086] In one embodiment of this application, the above-mentioned sight device may further include: a second communication module for communicating with other devices.

[0087] The aforementioned second communication module can be a Bluetooth communication module or an NFC communication module, etc. In one implementation, the sight device can communicate with the first communication module of the laser rangefinder through the second communication module to obtain data measured by the laser rangefinder. The sight device can also be connected to devices such as computers through the second communication module, allowing other users to view the content displayed on the sight device via a computer. Therefore, establishing a communication connection between the sight device and other devices through the second communication module enables information sharing between devices and improves the user experience.

[0088] Accordingly, based on Figure 1 ,like Figure 4 As shown, the method may further include:

[0089] Step S401: Establish a communication connection between the second communication module and the first communication module;

[0090] Step S402: Determine whether the connection was successfully established; if successful, proceed to step S101.

[0091] Step S401 described above can be executed automatically after the user installs and turns on the laser rangefinder and sight. If the communication connection is successfully established, the calibration interface will be entered automatically, and the laser rangefinder will automatically turn on the indicator beam emitting component to begin calibrating the rangefinder laser. If the connection fails to be established, it can be re-established. This enriches the user's calibration method options and improves the user experience.

[0092] like Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the calibration of a rangefinder laser in an embodiment of this application. Specifically, the sight device and the laser rangefinder device are paired and connected via Bluetooth. After successful connection, the calibration interface is automatically entered, and the indicator beam emission component of the laser rangefinder device is simultaneously activated. The sight device's attitude is then adjusted so that the indicator beam is aligned with the crosshair position of the calibration target; the positioning cursor in the calibration interface is then adjusted to move to the center of the target on the device screen, completing the calibration of the laser rangefinder device.

[0093] like Figure 6 As shown, Figure 6 This is another schematic diagram illustrating the calibration of the ranging laser in this application embodiment.

[0094] The left side represents the OLED screen; the angle between field of view boundary line 1 and field of view boundary line 2 represents the field of view of the aiming device; the right side represents the field of view of the aiming device. Figure 6Point A, the intersection of the OLED and the field-of-view boundary line 2, is the lowest point of the OLED and also the lower boundary of the sight's field of view. The sight works by displaying the sight's field of view on the OLED. That is, each point on the OLED corresponds to an image along a diverging straight line within the field of view. Taking point A as an example, point A on the sight's OLED displays the image along the field-of-view boundary line 2 at different distances.

[0095] When calibrating a laser rangefinder, such as Figure 6 As shown, even if the pointer beam and the central axis of the aiming device have a certain angle, as long as the center line of the field of view corresponding to the position of the positioning cursor on the OLED is adjusted to be parallel to each other, the target position measured by the ranging laser beam will be consistent with the target position determined by the center line of the field of view corresponding to the positioning cursor.

[0096] Specifically, such as Figure 6 As shown, first align the indicator beam with the "cross" position on the target. At this point, the indicator beam is a straight line (BE). Figure 6 The laser pointer line is shown in the image. At this point, the target's center point can be seen on the sight as point C on the OLED. Move the positioning cursor to point C on the OLED. The position of the positioning cursor at point C on the OLED then corresponds to the image along the straight line CD at different distances within the device's field of view. The center line CD corresponding to the positioning cursor is parallel to the pointer beam BE. Figure 6 The calibration line is parallel to the laser pointer line.

[0097] As can be seen, by applying the embodiments of this application, the complex calibration fixture is simplified into a simple visual laser calibration, which improves the operability of the product and enhances the diversity and ease of use of the product functions.

[0098] like Figure 7 As shown, Figure 7 This is a schematic diagram of the use of a sight device calibrated using the laser rangefinding calibration method provided in the embodiments of this application.

[0099] After calibrating the sight using the laser rangefinding calibration method provided in this application, the laser pointer beam is parallel to the center line of the target's field of view marked by the crosshair. Since the laser pointer beam is parallel to the rangefinding laser beam, the center line of the target's field of view is also parallel to the rangefinding laser beam. In practical applications, the size of the target being measured is usually much larger than the installation distance between the laser rangefinding device and the sight. Therefore, the distance between the target's field of view center line and the rangefinding laser beam has negligible impact on the actual range measurement. Because the target's field of view center line and the rangefinding laser beam are parallel, and the distance between them has negligible impact on the actual range measurement, it can be considered that the target's field of view center line and the rangefinding laser beam approximately coincide. In other words, the target seen through the crosshair is the same as the target actually measured by the rangefinding laser beam.

[0100] like Figure 7 As shown, for target 1 and target 2 at different distances, when the center line of the target's field of view marked by the crosshair is aligned with target 1 (or 2), the ranging laser beam is also aligned with target 1 (or 2). That is, when target 1 (or 2) is observed through the crosshair, the ranging laser beam is also measuring target 1 (or 2). Therefore, the sight device calibrated using the laser ranging calibration method provided in this application can accurately measure the distance between targets at different distances and the sight device.

[0101] The following is an exemplary description of a laser ranging device used in the embodiments of this application:

[0102] like Figure 8 As shown, Figure 8 A schematic diagram of a laser ranging device provided in this application is provided. The device may include:

[0103] An indicator beam emitting assembly 801 is used to emit an indicator beam, wherein the indicator beam;

[0104] The ranging laser beam emitting component 802 is used to emit a ranging laser beam, wherein the ranging laser beam and the indicating beam are parallel to each other.

[0105] The aforementioned laser ranging device may include an adjustable device, allowing the user to flexibly adjust the relative positions of the indicator beam emitting component 801 and the ranging laser beam emitting component 802. Specifically, the relative positions of the indicator beam emitting component 801 and / or the ranging laser beam emitting component 802 can be adjusted by using the adjustable device. The adjustable device may be a bolt, a fixing screw, etc. Of course, the indicator beam emitting component 801 or the ranging laser beam emitting component 802 may also be fixedly installed. In this application, it is sufficient to ensure that the position of at least one of the indicator beam emitting component 801 and the ranging laser beam emitting component 802 is adjustable within the laser ranging device.

[0106] The aforementioned laser rangefinder may also include an adapter 803, through which the laser rangefinder can be mechanically connected to the aiming device.

[0107] When designing the structure of a laser rangefinder, the positions of each component are usually predetermined, such as the positions of the ranging laser beam emitting component and the indicating beam emitting component, ensuring that the ranging laser beam and the indicating beam are parallel. However, in actual production, due to installation errors, even if the laser rangefinder is installed according to the design drawings, the ranging laser beam and the indicating beam may still not be parallel. Therefore, it is necessary to calibrate the ranging laser beam emitting component and the indicating beam emitting component during the production process of the laser rangefinder to ensure that the ranging laser beam and the indicating beam are parallel.

[0108] As one specific implementation method, such as Figure 9 As shown, the ranging laser beam emitting component and the indicating beam emitting component can be calibrated through the following steps:

[0109] Step S901: Emit a ranging laser beam, which is aligned with the third preset target position of the second target;

[0110] Step S902: Adjust the indicator beam to a fourth preset target position aligned with the second target, wherein the distance between the fourth preset target position and the third preset target position is a second distance, the second distance is the distance between the emission point of the indicator beam and the emission point of the ranging laser beam, and the direction between the third preset target position and the fourth preset target position is the same as the direction between the emission point of the ranging laser beam and the emission point of the indicator beam.

[0111] In step S901 above, the laser ranging device or adjustable device can be adjusted so that the ranging laser beam emitted by the ranging laser beam emitting component hits the third preset target position of the second target. The third preset target position can be arbitrarily selected according to actual needs.

[0112] As mentioned above, the ranging laser beam is invisible to the human eye. Therefore, it is necessary to use laser observation equipment such as white light sight to observe the ranging laser beam, and then adjust the position of the ranging laser beam emitting component so that the ranging laser beam emitted by the ranging laser beam emitting component hits the third preset target position of the second target.

[0113] After performing step S901 above, the current position of the ranging laser beam emitting component can be fixed. Specifically, the position of the laser ranging device can be fixed, or the position of the ranging laser beam emitting component can be fixed by fixing the aforementioned adjustable device; this application does not make specific limitations in this regard.

[0114] In step S902, the position of the indicator beam emitting component can be adjusted by adjusting the adjustable device or the laser ranging device, so that the indicator beam reaches the fourth preset target position of the second target. The distance between the fourth preset target position and the third preset target position is the second distance, which is the distance between the emission point of the indicator beam and the emission point of the ranging laser beam. The direction between the third preset target position and the fourth preset target position is the same as the direction between the emission point of the ranging laser beam and the emission point of the indicator beam.

[0115] The direction between the emitting point of the ranging laser beam and the emitting point of the indicating beam refers to the direction between the projection of the emitting point of the ranging laser beam onto the second target surface and the projection of the emitting point of the indicating beam onto the second target surface. As mentioned above, the emitting point of the indicating beam can be any point on the lens from which the indicating beam exits. Similarly, the emitting point of the ranging laser beam can also be any point on the lens from which the ranging laser beam exits.

[0116] The second target mentioned above can be preset using the following steps:

[0117] S1. Set a third preset target position at any position on the second target;

[0118] S2. Determine the second distance between the exit point of the indicator beam and the exit point of the ranging laser beam;

[0119] S3. Set a fourth preset target at a position on the second target at a distance equal to the second distance between the second target and the third preset target.

[0120] When setting the second target, there is no need to restrict the direction between the third and fourth preset target positions; it is sufficient to ensure that the distance between the third and fourth preset target positions is the second distance mentioned above.

[0121] Of course, the positions of the aforementioned ranging laser beam emitting component and the indicating beam emitting component can also be determined during the calibration process, rather than predetermined. In this scenario, the second distance can be set according to actual needs, such as 2cm, 5cm, etc. However, for actual products, the positions of the ranging laser beam emitting component and the indicating beam emitting component cannot coincide. If they do, it will cause obstruction of the ranging laser beam or the indicating beam. Therefore, it is necessary to ensure that the straight line formed by the aforementioned third preset target position and the fourth preset target position is not perpendicular to the straight line formed by the indicating beam emitting component and the ranging laser beam emitting component. Since the positions of the ranging laser beam emitting component and the indicating beam emitting component cannot coincide, if the straight line formed by the third preset target position and the fourth preset target position is perpendicular to the straight line formed by the indicating beam emitting component and the ranging laser beam emitting component, the ranging laser beam hitting the third preset target position and the indicating beam hitting the fourth preset target position will intersect, making it impossible for the ranging laser beam and the indicating beam to be parallel.

[0122] like Figure 10 As shown, Figure 10 This is a schematic diagram illustrating the calibration of the ranging laser beam emitting component and the indicating beam emitting component in this application. The specific process is as follows:

[0123] The ranging laser beam emitting assembly emits a ranging laser beam, which hits the black crosshair position on the target (viewed through a white light sight), and the laser ranging device is then fixed in place. The internal screws of the laser ranging device are adjusted to align the indicator beam emitting assembly, ensuring the indicator beam reaches the black dot position on the target. At this point, the ranging laser beam and the indicator beam are parallel, and calibration is complete.

[0124] Based on the same inventive concept, this application also provides a laser-assisted sight device, such as... Figure 11 As shown, the above-mentioned device may include:

[0127] The adjustment module 1103 is used to adjust the crosshair cursor in the image to a second preset target position aligned with the first target, wherein the distance between the second preset target position and the first preset target position is a first distance, the first distance is the distance between the aiming device and the emission point of the indicator beam in a first direction, and the first direction is the direction in which the second preset target position is located relative to the first preset target position.
