Description

Technical Field

[0001] This application belongs to the field of automotive lighting technology, and specifically relates to a 3D automotive lighting control method, device, and vehicle. Background Technology

[0002] With the continuous development of automotive intelligent technology, users' demands for vehicle experience are gradually increasing. The sense of interaction and ritual during vehicle use has become an important demand. Vehicle welcome functions, as a crucial part of user-vehicle interaction, have experienced rapid development and optimization. Currently, vehicle welcome functions are mostly triggered by key unlocking, and the vehicle will adjust various lights such as position lights, turn signals, headlights, and taillights to complete the welcome action. Simultaneously, related technological fields have also seen the emergence of solutions attempting to achieve 3D display effects for vehicle lights, such as 3D holographic fan devices, holographic projection automotive lights, and automotive lighting devices utilizing the principle of peripheral drift illusion. The industry is gradually exploring ways to enhance the technological feel of vehicles and the user interaction experience through upgraded lighting effects.

[0003] Existing vehicle lighting technologies still have technical shortcomings, failing to meet users' demands for true 3D lighting effects and a high-quality user experience. Specifically, traditional vehicle welcome lighting relies solely on simple changes in various headlights, resulting in planar light emission and a monotonous display. While existing 3D lighting technologies can only achieve pseudo-3D effects, failing to achieve a true 3D breakthrough in display principles, they cannot create clear, continuous 3D images or dynamic video effects. This makes it difficult to create a 3D lighting display with a realistic visual experience, leading to insufficient technological sophistication in vehicle lighting and a poor user-vehicle interaction experience during welcome lighting, thus failing to meet the core needs of users in the context of intelligent vehicle development. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a 3D vehicle lighting control method, device, and vehicle that generates clear and continuous 3D images or videos, enhancing the technological feel of vehicle lighting and resolving the problems of traditional vehicle lighting control being disconnected from vehicle modes and having poor interactivity.

[0005] In a first aspect, embodiments of this application provide a 3D vehicle lighting control device, including an acquisition module, a 3D data control module, a 3D data projection module, and a playback module; The acquisition module is used to acquire vehicle light association information in real time and receive user input information; The 3D data control module is used to generate 3D data based on the vehicle headlight association information and user input information, and then rotates and slices the 3D data along the central axis to form a planar image. The 3D data projection module is used in conjunction with the uniform rotation of the photosensitive rotating screen to project images onto the rotating screen, so that the images are displayed sequentially as the screen rotates, forming 3D images or 3D videos using the principle of visual persistence.

[0006] In some embodiments of this application, the 3D data control module prioritizes playing the image or video with the highest priority based on the preset priority of the image or video.

[0007] In some embodiments of this application, the acquisition module acquires first vehicle light association information when the vehicle is in welcome mode and detects that a user has arrived within a preset range around the vehicle.

[0008] In some embodiments of this application, when the acquisition module obtains the first vehicle light association information, the 3D data control module controls the execution of the corresponding welcoming action.

[0009] In some embodiments of this application, the acquisition module acquires the second vehicle light association information when the vehicle is in the "Follow Me Home" mode and detects that the user has gotten out of the car and closed the door.

[0010] In some embodiments of this application, when the acquisition module obtains the second vehicle light association information, the 3D data control module controls the execution of the corresponding shutdown action after a preset delay.

[0011] In some embodiments of this application, the acquisition module acquires third vehicle light association information when the vehicle is in normal mode and the vehicle is detected to be powered on and the door is scanned.

[0012] In some embodiments of this application, the 3D data control module controls the execution of corresponding welcoming actions when the acquisition module obtains the third vehicle light association information.

[0013] Secondly, embodiments of this application provide a 3D vehicle lighting control method, which utilizes a 3D vehicle lighting control device and includes the following steps: Real-time acquisition of vehicle light association information and receipt of user input information; 3D data is generated based on the vehicle headlight association information and user input information. The 3D data is then rotated and sliced ​​along the central axis to form a planar image. Start the photosensitive rotating screen and control it to rotate at a constant speed. Project a flat image onto the rotating photosensitive rotating screen so that the flat image is displayed sequentially as the photosensitive rotating screen rotates, forming a 3D image or 3D video using the principle of visual persistence.

[0014] Thirdly, embodiments of this application provide a vehicle, including a 3D vehicle lighting control device, a vehicle body, and vehicle lights mounted on the vehicle body. The vehicle lights include a 3D vehicle lighting controller, a photosensitive rotating screen, a motor, and a projection device.

[0015] Compared with the prior art, this application has the following advantages: 1. Breaking through the limitations of traditional planar and pseudo-3D display of vehicle lights, it achieves a true 3D dynamic lighting display effect. By rotating and slicing 3D data around the central axis and combining it with the uniform rotation of the photosensitive rotating screen and the projection of the projection device, it uses the principle of visual persistence to form clear and continuous 3D images or videos. Compared with the existing pseudo-3D vehicle light technology, it has achieved a technological breakthrough in display principle and enhanced the technological feel of vehicle lights. 2. To achieve the adaptation of vehicle light display effects to different vehicle usage modes, the corresponding vehicle light association information can be triggered based on user behavior in welcome mode, follow me home mode, and normal mode, and then the matching 3D display action or closing action can be executed. This allows the control of vehicle lights to be deeply integrated with the vehicle usage scenario, solving the problem of traditional vehicle light control being disconnected from vehicle modes and having poor interactivity, and building a scenario-based interaction link between the vehicle and the user. 3.

The device can convert 2D images or videos into 3D projection data and also supports the retrieval of pre-stored 3D data, meeting users' needs for personalized and customized vehicle lights. This breaks the limitations of traditional fixed vehicle light display effects that cannot be set independently, and enhances the user's driving experience and sense of participation.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] First of all, it should be noted that after analyzing the actual application of existing vehicle headlight control technology, it was found that traditional vehicle welcome and headlight control methods generally suffer from monotonous lighting display forms, with only planar light emission effects or pseudo-3D effects. The interaction experience between headlights and users is insufficient, and the movement of headlights cannot be accurately matched with different vehicle usage modes, resulting in a lack of personalized display capabilities. These problems combined make the technological and ceremonial feel of vehicle headlights insufficient, making it difficult to meet users' needs for intelligent and personalized vehicle interaction.

[0022] This invention constructs a 3D vehicle lighting control method, device, and vehicle. The technical solution takes the 3D vehicle lighting control device as the core and, in conjunction with the hardware structure of the vehicle lighting, realizes a 3D dynamic vehicle lighting display effect, adapting to the lighting needs of different vehicle usage modes. The specific implementation of this technical solution is described in detail below with reference to the embodiments.

[0023] In one exemplary embodiment, a 3D vehicle lighting control device is provided, with reference to... Figure 3 This illustration shows a structural diagram of the 3D vehicle light provided in this embodiment. The vehicle light includes a 3D vehicle light controller 103, a photosensitive rotating screen 101, a motor 102, and a projection device 104. The various hardware structures work together to provide the hardware foundation for the display of 3D images and videos. The specific structural arrangement is as follows: The 3D vehicle lighting controller 103 is the core of the entire vehicle lighting control system. It is electrically connected to the motor 102, the projection device 104, and the photosensitive rotating screen 101. It can control the speed of the motor 102, the projection frequency of the projection device 104, and the start / stop status of the photosensitive rotating screen 101. At the same time, it can receive control commands transmitted by the 3D vehicle lighting control device and feed back the operating status of the hardware to the 3D vehicle lighting control device, realizing information exchange between the hardware and the control device.

[0024] It should be noted that the various hardware structures of the 3D car lights perform different functions. The motor 102 provides power for the rotation of the photosensitive rotating screen 101, enabling it to rotate continuously at a constant speed. The rotation speed can be adjusted according to the needs of the 3D display effect, adapting to the display of projection slices at different frame rates. The photosensitive rotating screen 101 serves as the carrier for projection display, receiving planar images projected by the projection device 104. During rotation, it achieves continuous display of projection slices at different angles, thereby forming a visual 3D effect. The projection device 104 is the execution component for slice projection, projecting planar images processed with 3D data onto the photosensitive rotating screen 101. The projection frequency can be matched with the rotation speed of the motor 102, ensuring that the photosensitive rotating screen 101 can display the corresponding projection slice for each rotation angle.

[0025] The output of motor 102 is connected to the photosensitive rotating screen 101, enabling it to rotate around its central axis. During rotation, the motor maintains stable rotation speed, preventing issues like stuttering and ghosting in the 3D display due to speed fluctuations. The projection end of projection device 104 faces the display surface of photosensitive rotating screen 101, covering its effective display area and ensuring the projected image is displayed completely and clearly. The 3D vehicle lighting controller 103 has a built-in control program that adjusts the rotation speed parameters of motor 102 and the projection frequency parameters of projection device 104 in real time according to instructions from the 3D vehicle lighting control device, ensuring they are always matched. For example, to achieve a 120Hz 3D projection effect, motor 102 is controlled to run at 120×360 revolutions per second, while projection device 104 projects at a frequency of 1 / (120×360) frames per second.

[0026] refer to Figure 1 This diagram illustrates the block diagram of the 3D vehicle headlight control device provided in this embodiment. The device includes an acquisition module 20, a 3D data control module 21, a 3D data projection module 22, and a playback module 23. These modules cooperate to acquire vehicle headlight-related information, process 3D data, and play projected content, completing the entire process of 3D vehicle headlight control command output. The specific implementation methods of the modules are as follows: The acquisition module 20 is responsible for acquiring information. On the one hand, it can acquire vehicle light-related information in real time, and on the other hand, it can receive user input information, providing a data foundation and instruction basis for subsequent 3D data processing and vehicle light control.

[0027] The vehicle light association information refers to the correlation between the vehicle's current mode and user behavior. The acquisition module 20 can monitor the vehicle's operating mode and the user's behavioral state in real time. When the vehicle's current mode and the user's behavioral state meet the set conditions, the corresponding vehicle light association information is automatically acquired. When the vehicle is in welcome mode, the acquisition module 20 can monitor the user's location through the vehicle's sensors. When the user is detected to have reached a preset range around the vehicle, the first vehicle light association information is automatically acquired. When the vehicle is in follow-me-home mode, the acquisition module 20 can monitor the vehicle's door status and the user's exit action. When the user is detected to have exited the vehicle and closed the door, the second vehicle light association information is automatically acquired. When the vehicle is in normal mode, the acquisition module 20 can monitor the vehicle's power-on status and door scanning action. When the vehicle is detected to be powered on and the door is scanning, the third vehicle light association information is automatically acquired.

[0028] The acquisition module 20 can also receive information input by the user through channels such as the vehicle APP. The user can input the relevant information of the 3D animation or video effect to be displayed in the vehicle APP according to their own needs. After receiving the information, the acquisition module 20 transmits it synchronously to the 3D data control module 21 to realize the personalized customization of the vehicle light display effect and meet the user's personalized needs.

[0029] The 3D data control module 21 is the core processing module of the 3D vehicle lighting control device. It is used to generate 3D data based on the vehicle lighting association information and user input information, rotate and slice the 3D data along the central axis to form a planar image, and execute corresponding control actions based on the vehicle lighting association information transmitted by the acquisition module 20. It can also realize priority management of the displayed content.

[0030] The 3D data control module 21 can process the user input information transmitted by the acquisition module 20. If the user inputs 2D images or 2D video information, the module can convert the 2D images or 2D videos into 3D images or 3D videos through the built-in image conversion algorithm to generate 3D data that can be projected. At the same time, the module also supports the retrieval of pre-stored 3D data. If there is pre-stored 3D image or 3D video data in the storage device, it can be directly retrieved as 3D data for projection, thereby improving data processing efficiency.

[0031] After generating 3D data, the 3D data control module 21 slices the 3D data, rotating the 3D image or 3D video around the central axis to form multiple frames of planar images at different angles. For 3D images, the entire image is rotated around the central axis to generate 360 ​​frames of planar images at various angles; for 3D videos, each frame of the video is rotated around the central axis to generate 360 ​​frames of planar images at various angles, ensuring a complete and continuous 3D display effect after subsequent projection.

[0032] The 3D data control module 21 prioritizes the highest-priority images or videos based on preset image or video priorities. When the acquisition module 20 acquires the first headlight association information, the 3D data control module 21 immediately controls the execution of the corresponding welcoming action, initiating the 3D display process of the 3D headlights. When the acquisition module 20 acquires the second headlight association information, the 3D data control module 21 first delays for a preset time before controlling the execution of the corresponding shutdown action. The preset delay time can be set according to the user's needs to adapt to the lighting usage requirements of the "Follow Me Home" mode. When the acquisition module 20 acquires the third headlight association information, the 3D data control module 21 controls the execution of the corresponding welcoming action to meet the lighting display requirements of the vehicle in normal mode.

[0033] The playback module 23 is the execution output module of the 3D vehicle lighting control device. It is used to play the planar images transmitted by the 3D data control module 21, realizing the transmission of instructions and data between the control device and the vehicle lighting hardware. The 3D data projection module 22 is used to cooperate with the uniform rotation of the photosensitive rotating screen 101 to project the planar images onto the rotating photosensitive rotating screen 101. The planar images are displayed sequentially as the photosensitive rotating screen 101 rotates, forming 3D images or 3D videos using the principle of visual persistence, thus completing the final presentation of true 3D lighting effects.

[0034] In one exemplary embodiment, a 3D vehicle lighting control method is provided, referring to... Figure 2 The flowchart of the 3D vehicle headlight control method provided in this embodiment is shown. This method applies the aforementioned 3D vehicle headlight control device, in conjunction with the vehicle headlight hardware structure, to achieve full-process control of the 3D vehicle headlight. The specific steps and implementation methods are as follows: The first step is to obtain vehicle light association information in real time and receive user input information.

[0035] The second step is to generate 3D data based on the vehicle headlight association information and user input information, and then rotate and slice the 3D data along the central axis to form a planar image.

[0036] The third step is to start the photosensitive rotating screen 101 and control it to rotate at a constant speed, projecting the flat image onto the rotating photosensitive rotating screen 101, so that the flat image is displayed sequentially as the photosensitive rotating screen 101 rotates, and forming a 3D image or 3D video by utilizing the principle of visual persistence.

[0037] In practical applications, this 3D vehicle lighting control method can adjust the display effect according to different vehicle modes. In welcome mode, when a user approaches the vehicle, the headlights automatically display a 3D welcome image or video, enhancing the sense of ceremony when using the vehicle. In follow me home mode, after the user gets out of the car and closes the door, the headlights will display a 3D effect with a delay, providing the user with lighting and visual experience, and will automatically turn off after the delay ends. In normal mode, when the vehicle is powered on and the door is scanned, the headlights display a 3D effect, meeting the user's daily usage needs.

[0038] In one exemplary embodiment, a vehicle is also provided, which includes a vehicle body, headlights mounted on the vehicle body, and the aforementioned 3D headlight control device. The headlights include a photosensitive rotating screen 101, a motor 102, a 3D headlight controller 103, and a projection device 104. The headlights are electrically connected to the 3D headlight control device to achieve 3D control and display of the headlights. The specific vehicle implementation is as follows: The headlights are positioned in preset locations on the vehicle body. Depending on the vehicle's design requirements, the headlights can be placed at the front, rear, or sides of the vehicle to meet the lighting display and usage needs of different locations. The 3D headlight controller 103, photosensitive rotating screen 101, motor 102, and projection device 104 are all integrated into a unified 3D headlight structure, reducing the complexity of wiring inside the vehicle and improving space utilization.

[0039] The 3D headlight control device can be integrated into the vehicle's central control system, establishing data communication with the vehicle's overall control system to obtain real-time information on the vehicle's operating mode. Simultaneously, it can connect to the user's mobile terminal via an in-vehicle app to receive personalized input. Control commands sent by the 3D headlight control device to the headlights can be transmitted through the vehicle's internal communication bus, ensuring timely and accurate command transmission and achieving coordinated operation between headlight control and overall vehicle control.

[0040] Through the coordination of the 3D headlight control device and the headlight hardware, the vehicle achieves a true 3D headlight display effect, breaking the limitations of traditional planar lighting and pseudo-3D lighting. This allows the headlight movements to be precisely matched with different vehicle usage modes, enhancing the vehicle's technological feel and user interaction experience, and meeting users' needs for intelligent and personalized vehicle use.

[0041] refer to Figure 4This illustration demonstrates the welcoming effect of the 3D car lights provided in this embodiment. In achieving the 3D cube welcoming effect, the 3D data control module 21 rotates the 3D cube data around its central axis, generating 360 frames of planar images from various angles. The 3D car light controller 103 controls the motor 102 to rotate the photosensitive rotating screen 101 at a speed of 120×360 revolutions per second. Simultaneously, it controls the projection device 104 to project the 360 ​​frames of planar images onto the photosensitive rotating screen 101 one by one at a frequency of 1 / (120×360) second per frame. The continuous rotation of the photosensitive rotating screen 101, combined with the precise projection of the projection device 104, ultimately forms a 120Hz stereoscopic 3D cube welcoming effect. To achieve a dynamic 3D welcoming effect, each frame of the 3D video only needs to generate 360 ​​frames of planar images from various angles in the same manner, and then, through the coordinated operation of the motor 102 and the projection device 104, a continuous 3D dynamic projection effect can be formed.

[0042] It should be noted that the modules of the 3D vehicle lighting control device of the present invention can be integrated into the vehicle's central control chip via software programs, or implemented via independent hardware circuit boards, and can be flexibly adjusted according to the vehicle's hardware design requirements. The speed of the 3D vehicle lighting motor 102 and the projection frequency of the projection device 104 can be steplessly adjusted according to the actual 3D display effect requirements, adapting to different frame rates and styles of 3D images and videos. User input channels are not limited to in-vehicle apps; they can also be input via the vehicle's central control screen, voice commands, etc., further enhancing user convenience. Furthermore, the technical solution of the present invention is adaptable to vehicles of different brands and models; only minor parameter adjustments are needed based on the vehicle's structure and control requirements to achieve 3D vehicle lighting control and display, demonstrating high versatility and adaptability.

[0043] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
