Description

Technical Field

[0001] The present invention relates to the field of projection equipment control technology, and in particular to a laser projection equipment control method, device, projection equipment and storage medium. Background Art

[0002] With the popularity of laser TVs and laser projectors in people's lives, people have begun to pay attention to various problems that exist during use. Since laser devices such as laser TVs and laser projectors use laser light sources for projection, and the brightness of laser projections is relatively high, if the user accidentally looks directly at the light source during use, it is very easy to cause damage to the user's eyes. For example, when a user is using an ultra-short-throw laser projection device, because the focal length of the ultra-short-throw laser projection device is very short, it can be placed on a TV cabinet, very close to the projection wall. Because the side of the ultra-short-throw laser projection device close to the wall is usually equipped with various interfaces, such as HDMI interface, power interface, USB interface, etc., when the user needs to use the above interfaces, he needs to go over the ultra-short-throw laser projection device to plug and unplug, which may cause the problem of being irradiated by the laser.

[0003] In order to prevent the user's eyes from being hurt, existing laser projection equipment has installed an infrared sensor near the light outlet. When an object moving is detected within the projection range, the laser projection equipment is triggered to start the eye protection function, making the projection image darker. However, the detection range of the infrared sensor is limited in this way, resulting in a slow response of the eye protection function of the laser projection equipment and poor practicality. Summary of the invention

[0054] The embodiment of the present invention provides a method for controlling a laser projection device, referring to Figure 2 , Figure 2Schematic diagram of the flow chart of the first embodiment of the laser projection device control method of the present invention.

[0055] In this embodiment, the laser projection device control method includes:

[0056] Step S10, based on the first sensing device, detecting whether there is a moving object approaching the short-throw laser projection device;

[0057] Step S20, if yes, increasing the acquisition frequency of the second sensing device to the first target frequency;

[0058] Step S30, detecting whether the moving object is in a second detection area based on a second sensing device that collects data at the first target frequency;

[0060] The laser projection device control method of this embodiment is used for laser TV, laser projector, or other laser projection devices with brightness greater than 1000lm or laser projection devices that need to have eye protection function. Figure 3 , Figure 3 The device structure and projection schematic diagram of an embodiment of the laser projection device of the present invention, wherein the first sensing devices are numbered 1 and 2, and the second sensing devices are numbered 3 and 4; the light outlet of the short-focus projection device is located at the top of the device, that is, the first sensing device is arranged on the front side of the laser projection device, and the second sensing device is arranged on the top side of the laser projection device and is located near the light outlet. It should be noted that the front side of the laser projection device is the side of the laser projection device that is facing away from the projection image or screen, and when the user is watching a movie, the front side is arranged to face the user.

[0061] The following is a detailed description of each step:

[0062] Step S10, based on the first sensing device, detecting whether there is a moving object approaching the laser projection device in the first detection area;

[0063] In one embodiment, a first sensing device is used to detect whether a moving object is close to the laser projection device. Among them, the first sensing device is used to detect whether a moving object is close to the laser projection device. In order to achieve accurate detection, the detection range of the first sensing device needs to cover at least the front area of ​​the laser projection device. Taking the laser projection device as a short-focus laser projection device as an example, in general use scenarios, the short-focus laser projection device will be placed on a TV cabinet against the wall. Then, when the user approaches the TV cabinet and needs to clean the short-focus projection device or plug in and out the rear socket, it may be irradiated by the laser. Then, a first sensing device can be set at the front panel of the short-focus laser device to detect the first detection area in front to confirm whether there is a moving object close to the short-focus laser projection device. It should be noted that after the short-focus laser projection device is powered on, it detects whether there is a moving object in the first detection area corresponding to the first sensing device, that is, the detection is turned on once the short-focus laser projection device starts to emit light.

[0064] Step S20, if yes, increasing the acquisition frequency of the second induction device to the first target frequency;

[0065] In one embodiment, if the first sensing device detects that a moving object is approaching the short-focus laser projection device, a signal is sent to the main control IC, and the main control IC generates a corresponding preparation signal to the second sensing device, thereby increasing the acquisition frequency of the second sensing device to the first target frequency. Among them, when there is no moving object approaching the short-focus laser projection device, that is, when the second sensing device does not receive the preparation signal, it is in a state of a lower acquisition frequency or a state of zero acquisition frequency. When the second sensing device receives the preparation signal, it will be adjusted to the Standby state, that is, it is in a standby state, and its priority or response timeliness is higher. Therefore, in the Standby state, the acquisition (detection) frequency of the second sensing device is adjusted to the first target frequency, and the first target frequency is greater than the detection frequency of the second sensing device before receiving the preparation signal, so as to more sensitively detect whether there is a moving object in the second detection area of ​​the second sensing device.

[0066] Step S30: detecting whether the moving object is in a second detection area based on a second sensing device that collects data at the first target frequency.

[0067] It can be understood that the detection frequency of the second sensing device is increased to the first target frequency only when the user appears in the first detection area near the short-focus laser projection device to collect the sensor signal in the projection area of ​​the short-focus laser projection device (the second detection area), wherein the projection area of ​​the projection device is within the detection area of ​​the second sensing device.

[0068] Step S40: If yes, the projection image of the laser projection device is turned off or the brightness of the projection image of the laser projection device is reduced based on the preset eye protection instruction.

[0069] In this embodiment, when the second sensing device collects the sensing signal in the second detection area through the first target frequency, if a moving object is detected, the eye protection operation for the user is performed according to the preset eye protection instruction, that is, the laser projection device screen is turned off or the brightness of the laser projection device screen is reduced.

[0070] In this embodiment, the first sensing device detects whether there is a moving object approaching the laser projection device in the first detection area, and then increases the acquisition frequency of the second sensing device to the first target frequency, and then the second sensing device detects whether the moving object is in the second detection area based on the first target frequency. When the first sensing device detects that an object or a human body is approaching the laser projection device, the first sensing device "wakes up" the second sensing device, and increases the acquisition frequency of the second sensing device, so that it can timely and accurately collect the sensor signal of the moving object when the moving object approaches the projection device, thereby triggering the corresponding eye protection instruction, improving the response speed of the eye protection function of the laser projection device, and having strong practicality.

[0071] In addition, by cooperating with the first sensing device and the second sensing device, the positional relationship between the moving object and the first detection area and the second detection area can be detected respectively, so that the eye protection function of the laser projection device can be accurately activated according to the position of the moving object to prevent false triggering.

[0072] Furthermore, based on the first embodiment of the laser projection device control method of the present invention, a second embodiment of the laser projection device control method of the present invention is proposed.

[0073] Reference Figure 4 , Figure 4 Detailed flow chart of step S30 in an embodiment of the laser projection device control method of the present invention. In a second embodiment, the step of detecting whether the moving object is in the second detection area based on the second sensing device that collects at the first target frequency includes:

[0074] Step S31: detecting whether the moving object is in a second detection area within a first preset time based on a second sensing device that collects data at the first target frequency.

[0075] In this embodiment, when the second sensing device collects the sensing signal in the second detection area through the first target frequency, if a moving object is detected within the first preset time, the eye protection operation for the user is performed according to the preset eye protection instruction. By setting the detection time (first preset time) for the second sensing device, energy saving and environmental protection can be achieved.

[0076] Further, in one embodiment, before the step of closing the projection screen of the laser projection device or reducing the brightness of the projection screen of the laser projection device based on the preset eye protection instruction, the method further includes:

[0077] Step a: Generate a preset eye protection instruction based on the user's eye protection brightness setting instruction.

[0078] In one embodiment, the user can set the eye protection brightness according to personal preferences to meet the user's personalized needs. It is understandable that different users have different preferences or acceptable ranges for brightness. Therefore, an optional instruction is provided, and the user can set the eye protection brightness in the operating system or APP corresponding to the short-focus laser projection device. Specifically, one implementation method can provide a screen brightness reduction ratio for the user to choose, generate an eye protection brightness setting instruction based on the screen brightness reduction ratio selected by the user, and reduce the screen brightness to a preset ratio of the current screen brightness based on the preset eye protection instruction, such as halving the original brightness; another implementation method can provide a screen brightness eye protection value for the user to choose, and then generate an eye protection brightness setting instruction based on the screen brightness eye protection value selected by the user. Assuming that the laser brightness is expressed as a percentage, the screen brightness eye protection value selected by the user is 50%, then when the second sensing device detects a moving object, the screen brightness of the short-focus laser projection device is reduced to 50% according to the eye protection instruction.

[0079] Furthermore, in one embodiment, after the step of detecting whether the moving object is in a second detection area based on the second sensing device that collects data at the first target frequency, the method further includes:

[0080] Step S32: if not, reducing the first target frequency of the second induction device to a second target frequency.

[0081] In one embodiment, it is understandable that if the first sensing device has been detecting a moving object within the first detection range, that is, there is a moving object near the short-focus laser projection device, it will continue to send a preparation signal to the second sensing device so that it continues to detect through the first target frequency; correspondingly, if the second sensing device does not detect the moving object, the acquisition frequency of the second sensing device is reduced to the second target frequency, that is, from the first target frequency to the second target frequency. Prompt information can also be generated to inform the user that there are obstacles in the first detection area corresponding to the first sensing device, such as chairs, toys and other moving objects, prompting the user to remove them. Further, the user can choose to set the obstacle identified by the first sensing device to be ignored, that is, if a moving object is always identified at the same position and exceeds the preset time, that is, it is determined that the second sensing device has not detected the moving object within the first preset time, and a prompt message is sent to the user to let the user confirm the moving object information. If it is confirmed that it is an obstacle such as a chair, table, etc., it can be set to be ignored, that is, when the first sensing device recognizes the signal corresponding to the moving object, it does not send a preparation signal to the second sensing device.

[0082] Further, in one embodiment, if yes, the step of increasing the acquisition frequency of the second induction device to the first target frequency comprises:

[0083] Step S11, if yes, detecting the trigger duration of the moving object in the first detection area, and determining whether the trigger duration is greater than a second preset time;

[0084] Step S12: If yes, then the step of increasing the acquisition frequency of the second induction device to the first target frequency is performed.

[0085] In one embodiment, if a moving object is detected approaching a short-focus laser projection device, its trigger duration can be detected, that is, how long the moving object has been near the short-focus laser projection device. It is understandable that if the user only passes by the projection device, or throws an object through the detection range of the first sensing device, then there is no need to turn on the second sensing device. Therefore, it is possible to set the operation of increasing the acquisition frequency of the second sensing device when the trigger duration of the moving object exceeds the second preset time, which can reduce the energy consumption wasted due to turning on the second sensing device due to unnecessary detection to a certain extent. It should be noted that this judgment logic can be implemented together with the judgment logic in the other embodiments, or it can be set separately.

[0086] Further, in one embodiment, if yes, the step of increasing the acquisition frequency of the second induction device to the first target frequency comprises:

[0087] Step S13, if yes, detecting the distance between the moving object and the laser projection device to determine whether it is less than a preset distance;

[0088] Step S14: if yes, then the step of increasing the acquisition frequency of the second induction device to the first target frequency is performed.

[0089] In one embodiment, if the first sensing device detects that a moving object is close to a short-focus laser projection device, it detects whether the distance between the moving object and the laser projection device is less than a preset distance. If so, the acquisition frequency of the second sensing device is increased to the first target frequency. It is understandable that if a user places a coffee table in front of a TV cabinet and the distance from the TV cabinet is close to the TV cabinet and is within the detection range of the first sensing device, the moving object may be detected all the time, causing a false trigger. For example, if the detection range of the first sensing device is 1m, and the coffee table is placed 80cm away from the projection device, the moving object will be detected all the time, causing a false trigger. Therefore, the user can set the eye protection instruction trigger range, that is, the preset distance, by himself. For example, when the APP is opened, the distance between the moving object and the projection device is displayed on the operation interface based on the moving object information collected by the first sensing device. If the user determines that the moving object is fixed at this position, it is easy to think that the user will only move between the coffee table and the TV cabinet, so the eye protection instruction trigger range can be set to within 80cm. If the first sensing device detects an object outside the trigger range of the eye protection instruction, the step of increasing the acquisition frequency of the second sensing device to the first target frequency will not be executed, thereby further reducing the probability of false triggering and improving detection accuracy.

[0090] This embodiment determines whether a moving object is detected within the first preset time when the second sensing device collects the sensor signal according to the first target frequency. If the second sensing device does not detect the moving object, the collection frequency of the second sensing device is reduced to the second target frequency, thereby reducing the probability of false triggering and achieving energy saving. In addition, eye protection brightness is provided for users to choose, and personalized eye protection instructions are generated, which can be adaptively generated according to user needs; further, when there is a moving object in the first detection area, by setting a second preset time, when the trigger duration of the moving object in the first detection area is greater than the second preset time, the collection frequency of the second sensing device is increased; and the distance between the moving object and the laser projection device is detected to determine whether it is less than the preset distance. If it is less than the preset distance, the collection frequency of the second sensing device is increased, thereby improving the accuracy of trigger recognition and reducing unnecessary energy consumption of the second sensing device.

[0091] Furthermore, based on the previous embodiments of the laser projection device control method of the present invention, a third embodiment of the laser projection device control method of the present invention is proposed.

[0092] Reference Figure 5, Figure 5 This is a schematic diagram of an embodiment of a laser projection device of the present invention. In the third embodiment, taking the laser projection device as a short-focus projection device as an example, the first sensing device is arranged on the peripheral side of the short-focus laser projection device that is not facing the projection screen, and the second sensing device is arranged on the side of the short-focus laser projection device where a light outlet is provided.

[0093] Specifically, Figure 5 The rectangular area at the rear is the screen, and the cylindrical area at the front is the short-focus laser projection device. The top of the device is provided with a rectangular light outlet, and the second sensing device is marked as B in front of the light outlet, and the first sensing device is marked as A on the front side of the short-focus laser projection device facing away from the projection screen. It can be understood that the first sensing device is used to detect whether there is a moving object approaching the short-focus laser projection device. Therefore, in this embodiment, preferably, the first sensing device is arranged on the front side of the laser projection device, and the front side of the laser projection device faces away from the projection screen formed on the screen, so as to better cover the range of moving objects in the actual application scene.

[0094] Optionally, the first sensing device may also be arranged on the left side and / or right side of the laser projection device. It is understandable that the first sensing device may be arranged on at least one of the front side, the left side and the right side of the laser projection device.

[0095] It should be noted that the number, spacing and position of the first sensing devices can be set according to actual requirements such as the sensing range of the first sensing devices and the size of the projection device. In addition, the number and spacing of the second sensing devices set on the same surface of the light outlet can also be set according to actual requirements. Figure 5 As shown in , the first sensing device can be arranged around the peripheral side of the short-focus laser projection device. In addition, the projection device is not limited to a cylinder, a cuboid, etc., and its shape is not limited. Figure 6 , Figure 6 It is a schematic diagram of another embodiment of the laser projection device of the present invention. In this embodiment, the short-focus laser projection device is a rectangular parallelepiped, wherein the element marked as A is a first sensing device, and the element marked as B is a second sensing device.

[0096] The present invention also provides a laser projection equipment control device. Figure 7 As shown, Figure 7 It is a functional module diagram of an embodiment of a laser projection equipment control device of the present invention.

[0097] The laser projection device control device of the present invention comprises:

[0098] A first sensing device 10, used to detect whether there is a moving object approaching the laser projection device in a first detection area;

[0099] An adjustment module 20, configured to increase the acquisition frequency of the second sensing device to a first target frequency if a moving object is detected in the first detection area close to the laser projection device;

[0100] A second sensing device 30, used for collecting data at the first target frequency to detect whether the moving object is in a second detection area;

[0101] The eye protection module 40 is used to close the projection picture of the laser projection device or reduce the brightness of the projection picture of the laser projection device based on a preset eye protection instruction if it is detected that the moving object is in the second detection area.

[0102] Optionally, the second inductive device is further used for:

[0103] Based on the second sensing device that collects data at the first target frequency, detecting whether the moving object is in a second detection area within a first preset time;

[0104] If not, the first target frequency of the second inductive device is reduced to a second target frequency.

[0105] Optionally, the adjustment module is further used for:

[0106] If it is detected that a moving object is close to the laser projection device in the first detection area, detecting the trigger duration of the moving object in the first detection area, and determining whether the trigger duration is greater than a second preset time;

[0107] If yes, the step of increasing the acquisition frequency of the second induction device to the first target frequency is performed.

[0108] Optionally, the adjustment module is further used for:

[0109] If it is detected that a moving object is approaching the laser projection device in the first detection area, the distance between the moving object and the laser projection device is detected to determine whether it is less than a preset distance;

[0110] If yes, the step of increasing the acquisition frequency of the second induction device to the first target frequency is performed.

[0111] The invention also provides a storage medium.

[0112] The storage medium of the present invention stores a laser projection device control program, and when the laser projection device control program is executed by a processor, the steps of the laser projection device control method described above are implemented.

[0113] The method implemented when the management program running on the processor is executed can refer to the various embodiments of the management method of the present invention, and will not be described in detail here.

[0114] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or system. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or system including the element.
