[0043] Figure 2 is a structural block diagram of an in-vehicle projector control device provided by an embodiment of the present invention. Detailed Embodiments

[0044] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0045] When watching a video using an in-vehicle projector, due to the vehicle space, the use experience may be affected by object occlusion, and it may also affect the safe driving of the driver when watching the video. To solve the above technical problems, the present invention discloses an in-vehicle projector control method, the core idea of which is to detect whether the picture area of the projection picture of the in-vehicle projector and a preset area in the front row of the vehicle behind the projection screen are blocked. If it is blocked, the play mode of the in-vehicle projector is switched to the pause mode.

[0046] Reference Figure 1 , which shows a flowchart of the steps of a vehicle-mounted projector control method provided by an embodiment of the present invention. Among them, the vehicle-mounted projector is arranged in the vehicle, and a projection screen is arranged behind the front row seats of the vehicle so that the projection image of the vehicle-mounted projector is displayed on the projection screen. The method includes:

[0047] Step 101, when it is detected that the vehicle-mounted projector is in the playback mode, obtain the first state information of the screen area displaying the projection image, and / or the second state information of a preset area in the front row of the vehicle behind the projection screen.

[0048] In an embodiment of the present invention, the vehicle is provided with a vehicle-mounted projector, and the projection screen for displaying the projection image of the vehicle-mounted projector can be arranged behind the front row seats of the vehicle, so that the user on the rear row seat of the vehicle can watch the video projected by the vehicle projector through the projection screen.

[0049] When using the vehicle-mounted projector, the vehicle can obtain the working state of the vehicle-mounted projector. When it is detected that the vehicle-mounted projector is in the playback mode, the first state information of the screen area of the projector image can be obtained, and / or the second state information of a preset area in the front row of the vehicle behind the projection screen.

[0050] In one example, a first sensor and a second sensor can be arranged on the vehicle. The first sensor can be arranged on the vehicle-mounted projector, and the second sensor can be arranged in the vehicle central control platform area or at a preset position in the front row of the vehicle. The specific setting position is not specifically limited in this application. The first state information of the screen area displaying the projection image can be obtained according to the first sensor arranged on the vehicle-mounted projector, and / or the second state information of the preset area in the front row of the vehicle can be obtained according to the second sensor arranged in the preset area in the front row of the vehicle. In this application, the first sensor and the second sensor can be infrared sensors. The infrared sensors can continuously emit infrared rays to the area where the state information is to be obtained, and the first state information and the second state information are obtained according to the infrared rays. In this application, the first sensor and the second sensor can also be other sensors, as long as they can detect whether there is an object blocking the area where the state information is obtained. This application does not make specific limitations here.

[0051] Step 102, determine whether the screen area is blocked according to the first state information to obtain a first determination result, and / or determine whether the preset area in the front row of the vehicle is blocked according to the second state information to obtain a second determination result.

[0052] In an embodiment of the present invention, after obtaining the first state information of the screen area for displaying the projection screen and / or the second state information of the preset area in the front row of the vehicle behind the projection screen, it is possible to determine whether the screen area for displaying the projection screen is blocked according to the first state information to obtain a first determination result, and / or it is possible to determine whether the preset area in the front row of the vehicle behind the projection screen is blocked according to the second state information to obtain a second determination result. When the screen area for displaying the projection screen is blocked, it will affect the user's viewing experience of the video. Therefore, further processing is performed according to the first state information to improve the user's viewing experience of the video. When the user is watching a video, it may affect the driver's concentration on driving due to the excessive volume of the video or the exciting plot of the video. If it affects the driver's driving, at this time, the driver can place an object in the preset area in the front row of the vehicle behind the projection screen. Placing the object can indicate that the driver is currently affected and it affects safe driving. Therefore, further processing can be performed according to the second state information to prevent the driver from being affected and improve driving safety.

[0053] In one example, to determine whether the screen area for displaying the projection screen is blocked according to the first state information, it can be determined whether it is blocked according to the size of the blocked area of the screen area for displaying the projection screen. After obtaining the first state information, it is judged whether the first blocked area in the first state information is greater than the first preset area. If it is greater than the first preset area, it can be determined that the screen area for displaying the projection screen is blocked. To determine whether the preset area in the front row of the vehicle behind the projection screen is blocked according to the second state information, it can be determined whether it is blocked according to the size of the blocked area of the preset area in the front row of the vehicle behind the projection screen. After obtaining the second state information, it is judged whether the second blocked area in the second state information is greater than the second preset area. If it is greater than the second preset area, it can be determined that the preset area in the front row of the vehicle behind the projection screen is blocked.

[0054] Step 103, if the first determination result and / or the second determination result is blockage, then switch the playback mode to the pause mode.

[0055] In an embodiment of the present invention, after obtaining the first determination result and the second determination result, corresponding processing can be performed according to the first determination result and the second determination result. If the first determination result is blockage, indicating that the screen area for displaying the projection screen is in a blocked state, then the playback mode of the in-vehicle projector can be switched to the pause mode to prevent the user's viewing experience from being affected by the blocked screen area when watching the video. And / or, if the second determination result is blockage, indicating that the preset area in the front row of the vehicle behind the projection screen is in a blocked state, then the playback mode of the in-vehicle projector can be switched to the pause mode, and the video playback can be paused to prevent the driver from being affected by the video playback and affecting safe driving.

[0056] In one example, if the first determination result is occluded, and / or the second determination result is occluded, a first instruction to switch the playback mode to the pause mode may be generated, and the first instruction may be executed. Specifically, if the first determination result is occluded, and / or the second determination result is occluded, an instruction to disconnect the combined switch circuit of the in-vehicle projector is generated, and the instruction to disconnect the combined switch circuit is executed to pause the playback of the target video. The combined switch circuit of the in-vehicle projector is used to control the pause and playback of the in-vehicle projector and to switch between the playback mode and the pause mode of the in-vehicle projector.

[0057] In an embodiment of the present application, after switching the playback mode to the pause mode through the first determination result and / or the second determination result, the vehicle may continue to obtain the working state of the in-vehicle projector, may obtain third state information of the screen area for displaying the projector screen, and fourth state information of a preset area in the front row of the vehicle behind the projection screen.

[0058] In one example, the third state information of the screen area for displaying the projection screen may be obtained according to the first sensor provided on the in-vehicle projector, and the fourth state information of the preset area in the front row of the vehicle may be obtained according to the second sensor provided in the preset area in the front row of the vehicle.

[0059] In an embodiment of the present invention, after obtaining the third state information of the screen area for displaying the projection screen and the fourth state information of the preset area in the front row of the vehicle behind the projection screen, it may be determined whether the screen area for displaying the projection screen is unoccluded according to the third state information to obtain a third determination result, and it may be determined whether the preset area in the front row of the vehicle behind the projection screen is unoccluded according to the fourth state information to obtain a fourth determination result. When the screen area for displaying the projection screen is unoccluded, to enhance the user experience of watching the video, the video may be continued to be played, and further processing may be performed according to the third state information to enhance the user experience of watching the video. When the user is watching the video, it may affect the driver's concentration on driving due to reasons such as too loud a volume of the video being watched or because of exciting plot of the video. If it does not affect the driver's driving, at this time, the driver may take away the object placed in the preset area in the front row of the vehicle behind the projection screen, and taking away the object may indicate that the driver is not affected at present, and further processing may be performed according to the fourth state information.

[0060] In one example, the third state information determines whether the screen area of the displayed projection screen is unobstructed. It can be determined whether it is obstructed according to the size of the area of the screen area of the displayed projection screen that is obstructed. After obtaining the third state information, it is judged whether the third occlusion area in the third state information is less than the first preset area. If it is less than the first preset area, it can be determined that the screen area of the displayed projection screen is unobstructed. The fourth state information determines whether the preset area in the front row of the vehicle behind the projection screen is unobstructed. It can be determined whether it is obstructed according to the size of the area of the preset area in the front row of the vehicle behind the projection screen that is obstructed. After obtaining the fourth state information, it is judged whether the fourth occlusion area in the fourth state information is less than the second preset area. If it is less than the second preset area, it can be determined that the preset area in the front row of the vehicle behind the projection screen is unobstructed.

[0061] In an embodiment of the present invention, after obtaining the third determination result and the fourth determination result, corresponding processing can be performed according to the third determination result and the fourth determination result. If the third determination result and the fourth determination result are unobstructed, it indicates that the screen area of the displayed projection screen is in an unobstructed state, and the preset area in the front row of the vehicle behind the projection screen is also in an unobstructed state. Then, the pause mode of the in-vehicle projector can be switched to the play mode to continue allowing the user to watch the video, enhancing the user's viewing experience.

[0062] In one example, if the third determination result and the fourth determination result are unobstructed, a second instruction to switch the pause mode to the play mode can be generated and the second instruction can be executed. Specifically, if the third determination result and the fourth determination result are unobstructed, an instruction to close the combined switch circuit of the in-vehicle projector is generated, and the instruction to close the combined switch circuit is executed to continue playing the target video. Thus, the playback state of the in-vehicle projector for playing the video is controlled, enhancing the user's viewing experience.

[0063] In an embodiment of the present application, when it is detected that the in-vehicle projector is in the play mode, the first state information of the screen area of the displayed projection screen and / or the second state information in the preset area in the front row of the vehicle behind the projection screen is obtained; according to the first state information, it is determined whether the screen area is obstructed to obtain a first determination result, and / or according to the second state information, it is determined whether the preset area in the front row of the vehicle is obstructed to obtain a second determination result; if the first determination result and / or the second determination result is obstructed, the play mode is switched to the pause mode. Thus, the playback state of the in-vehicle projector for playing the video is controlled, avoiding affecting the user's viewing experience due to obstruction, and at the same time avoiding affecting the safe driving of the driver due to playing the video.
