[0001] This application relates to the field of vehicle intelligent control technology, and in particular to a control method, electronic device and vehicle for taking photos outside the vehicle. Background Technology

[0002] Currently, most vehicles are equipped with external cameras for recognizing and photographing the external environment. Some high-end vehicles also feature external projection lights to project patterns or text, allowing interaction with people outside the vehicle. When users are driving and want to take photos to document their trip, they often find themselves unable to take many pictures due to a lack of selfie devices or other passersby. External cameras and projection lights can effectively solve this problem, improving the user experience and maximizing the use of various vehicle components. Therefore, there is a pressing need for a solution to control external cameras for taking photos outside the vehicle. Summary of the Invention

[0003] In view of this, the purpose of this application is to propose a control method, electronic device and vehicle for taking photos outside the vehicle, which guides the user to stand and pose by projecting a projection lamp and takes photos of the user, avoiding the problem that the user needs to ask for help to take photos of a specific position.

The projected content is projected onto the projection position, and a photo is taken after the shooting conditions are met to obtain an initial photo. The initial photo is then post-processed according to the shooting mode to obtain an output photo.

[0005] Optionally, determining the shooting position and corresponding shooting posture based on the external environment image and shooting mode includes: The number of people taking photos and the type of environment are determined based on the images of the external environment of the vehicle. Determine the shooting direction based on the shooting mode; In response to the existence of a first shooting direction that is the same as the projection direction of the projector lamp, the shooting position and corresponding shooting posture are determined according to the number of people taking photos and the environment type. In response to the absence of the first shooting direction in the shooting direction, the shooting position is marked as empty, and the shooting posture is determined according to the number of people taking photos and the environment type.

[0006] Optionally, determining the shooting direction based on the shooting mode includes: In response to the shooting mode being panoramic, all directions are determined as the shooting direction; In response to the shooting mode being a non-panoramic mode and the existence of a user selection operation, the selected direction corresponding to the user selection operation is determined as the shooting direction; In response to the shooting mode being a non-panoramic mode and the absence of user selection, the projection direction of the projector lamp is determined as the shooting direction.

[0007] Optionally, determining the shooting position and corresponding shooting pose based on the number of people taking photos and the environment type includes: Based on the environment type, determine the initial recommended location for taking photos in the external environment image; The initial recommended locations are filtered based on their priority and the number of people taking photos to obtain image recommended locations; Based on the recommended image location and the body shape data of each photographer, the recommended pose and standing position of each photographer are determined. The recommended poses of the photographers are integrated to obtain the shooting pose. The standing positions of the photographers are integrated to obtain the shooting position.

[0008] Optionally, determining the projection position of the projected content in the external environment based on the photographing position includes: Based on the photographing position, a location is matched in the external environment, and the matched actual position is determined as the projected position.

[0009] Optionally, determining the projected content based on the shooting posture, the shooting position, and the shooting prompt includes: Based on the photographing positions, the position markers of each photographer are arranged in a specific order; Arrange the photo-taking poses corresponding to the photo-taking positions to the positions indicated by the preset arrangement direction; The photo prompts are arranged in a position that does not overlap with the photo pose or the position marker to obtain the projected content.

[0010] Optionally, the step of taking a photo after the shooting conditions are met to obtain an initial photo includes: The current countdown timer is determined based on the countdown data in the photo-taking prompt. In response to the current timer being zero, it is determined that the shooting conditions are met, and the vehicle-mounted camera is controlled to take a picture to obtain the initial photo.

[0011] Optionally, the step of post-processing the initial photo according to the shooting mode to obtain an output photo includes: In response to the shooting mode being either panoramic or multi-directional, the initial photo is stitched and enhanced to obtain the output photo. In response to the shooting mode being a one-way mode, the initial photo is beautified to obtain the output photo.

[0014] As described above, the vehicle exterior photography control method, electronic device, and vehicle provided in this application perceive the external environment through external environmental images. Under the selected shooting mode, it recommends the most suitable shooting posture and position for the user, ensuring that the photos best suit the external environment. The shooting posture and position need to be output via projection. Therefore, the projection position of the content in the external environment needs to be determined based on the shooting position, and the projection content needs to be determined based on the shooting posture, shooting position, and shooting prompts. This guides the user in positioning and posing. After projection is complete and shooting conditions are met, the camera takes a photo of the prepared user and processes the photo according to the shooting mode to obtain a photo that meets the user's needs. This satisfies the user's requirement to take photos of specific locations without third-party assistance, thereby improving the user experience and enhancing the vehicle's intelligence.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. Words such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Words such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0019] In this article, it is important to understand that any number of elements in the accompanying figures is for illustrative purposes and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0020] Based on the above background description, the following situations also exist in the related technologies: Most users have a need to take photos while on road trips; many enjoy driving and capturing the journey's moments and scenery. However, in the actual shooting process, users often face the following challenges: Selfie perspectives are limited: Traditional selfie methods are limited by arm length or selfie sticks, making it difficult to obtain more creative or wider angles and to ideally blend with the vehicle and its surroundings.

[0021] Relying on strangers for assistance: In popular tourist spots or remote areas, it may be difficult to find suitable strangers to help with taking photos in a timely manner, or communication problems may prevent the desired shooting results from being achieved.

[0022] Special scenes are difficult to record: such as at night or in scenes with complex lighting, ordinary mobile phone shooting is difficult to balance the exposure of the person and the background, and additional lighting equipment or techniques are required.

[0023] Most vehicles are equipped with external cameras for recognizing and photographing the external environment. They also often feature external projection lights to project patterns or text, allowing interaction with people outside the vehicle. When users are out driving and need to take photos, they often find themselves unable to capture more pictures due to a lack of selfie cameras or other passersby. External cameras and projection lights can effectively solve this problem, improving the user experience and maximizing the use of various vehicle components. Therefore, there is a pressing need for a solution to control external cameras for taking photos outside the vehicle.

[0024] The following describes in detail, with reference to the accompanying drawings, the control method for taking photos outside a vehicle provided by the embodiments of this application.

[0025] In some embodiments, such as Figure 1 As shown, a method for controlling external vehicle photography includes: Step 101: Determine the shooting position and corresponding shooting posture based on the external environment image and shooting mode.

[0026] In practical implementation, vehicles can be equipped with a comprehensive external environment perception system. This system achieves environmental perception through multi-sensor fusion, including wide-angle camera modules, telephoto / zoom camera modules, thermal infrared camera modules, and lidar and millimeter-wave radar modules. For photo guidance, the system primarily relies on camera modules deployed within the vehicle. To ensure omnidirectional, multi-angle shooting, at least one camera is positioned in each of the four directions: front, rear, left, and right. This includes a front-facing camera capturing the front of the vehicle, a rear-facing camera capturing the rear, a left-facing camera capturing the left side, and a right-facing camera capturing the right side. These external cameras act as the "eyes" of the vehicle's infotainment system, responsible for capturing high-quality image data. Vehicles typically feature a 360-degree surround-view camera system. These cameras are installed in locations such as the front grille, rear bumper, and left and right side mirrors, forming a comprehensive visual perception network. These cameras generally use wide-angle or fisheye lenses, possessing a large field of view (FOV), typically exceeding 190 degrees, capable of covering a wide area around the vehicle.

[0027] Alternatively, you can use the front camera, rear camera, left camera, and right camera to shoot from four directions, or you can use a 360° camera instead. However, the 360° camera has some distortion, which affects the shooting scene. Therefore, if the cost allows, you should prioritize using the front camera, rear camera, left camera, and right camera to shoot from four directions.

[0028] Optionally, the shooting range of the front, rear, left, and right cameras must all be greater than or equal to 90° to ensure that the four cameras can cover the entire field of view of the vehicle in all four directions. Alternatively, the shooting range of each of the four cameras can be set to 94°, meaning there is a 2° overlap between the shooting ranges of any two adjacent cameras. This avoids situations where camera installation errors prevent the four cameras from failing to cover a 360° panoramic view around the vehicle, resulting in uncovered areas during guidance and shooting. A more conservative strategy can be adopted to further increase the angle of the overlapping area. For example, setting the shooting range of each of the four cameras to 100°, with a 5° overlap between the shooting ranges of any two adjacent cameras, ensures that even with some installation errors, the shooting angle covers the entire direction of the vehicle, avoiding missed shots and failed guidance.

[0029] Optionally, since vehicle projection lights are generally installed within the vehicle's headlight assembly, they can deeply integrate advanced projection functions (such as road information prompts and adaptive high beams) with the original lighting system, achieving "precise lighting + precise display." Therefore, the optimal photo guidance position is always the first direction in front of the vehicle. The technical parameters of each camera directly affect image quality. High-end automotive cameras typically use all-glass aspherical lenses and are equipped with large apertures (such as f / 1.5) to increase light intake and improve performance in low-light environments. Image sensors mostly use CMOS type, with high dynamic range (up to 120dB) and good low-light sensitivity (approximately 0.1 lux), ensuring clear images under various lighting conditions. Furthermore, automotive cameras need to meet stringent automotive-grade requirements, such as AEC-Q100 certification, a wide operating temperature range (-40℃ to 105℃), and an IP69K protection rating, capable of withstanding harsh environmental conditions. In exterior photography systems, these cameras are not only used for final shooting but also monitor the environment and people in real time during the process, providing raw data for AI analysis. Multi-camera collaboration enables shooting from various angles, such as front, rear, side, and panoramic views. Some high-end systems also employ retractable and rotatable camera designs, adjusting the shooting angle via an electric mechanism to achieve a better compositional perspective. High-performance automotive cameras are typically positioned at the front of the vehicle, capturing clearer photos. Therefore, the shooting angle of the front camera can be increased to maximize its utilization. For example, a front camera with a shooting angle covering at least 150° can be selected, and the remaining 210° shooting range can be evenly distributed among the rear, left, and right cameras, with each camera configured with a minimum shooting range of 70°.

[0030] The system uses a pre-built panoramic camera module to acquire images or videos of the vehicle's 360° surroundings, providing images of the external environment and reflecting the current scene. This data is then used to determine the shooting position and pose.

[0031] The shooting mode is manually set according to user preferences and needs. If the user does not manually set the shooting mode, the default shooting direction is the front of the vehicle. Shooting modes are divided into two main categories: panoramic mode and non-panoramic mode. Panoramic mode uses the front, rear, left, and right cameras simultaneously to capture a panoramic view of the vehicle in all four directions. Non-panoramic mode means that at least one direction of the camera is not captured, i.e., the vehicle cannot be covered in a 360° field of view.

[0032] If further subdivision is needed, non-panoramic modes can be divided into one-way shooting mode, two-way shooting mode, and three-way shooting mode. One-way mode means that the camera is used to take pictures in one direction. If only the front camera is used to take pictures, it corresponds to the front shooting mode; if only the rear camera is used to take pictures, it corresponds to the rear shooting mode; if only the left camera is used to take pictures, it corresponds to the left shooting mode; and if only the right camera is used to take pictures, it corresponds to the right shooting mode.

[0033] Two-way mode means that cameras in two directions are used simultaneously to take pictures, and the user needs to manually select the two directions. Similarly, three-way mode means that cameras in three directions are used simultaneously to take pictures. In both two-way and three-way modes, the user needs to manually select the camera, and the system can also recommend directions based on images of the external environment.

[0034] Users can activate the exterior camera function in multiple ways, showcasing the system's multimodal interactive design. The main activation methods include in-car central control screen touch control, remote control via a mobile app, and in-car voice commands. Each method has its advantages and suits different usage scenarios: the central control screen provides a rich visual settings interface; the mobile app allows users to pre-configure the system outside the vehicle; and voice control allows users to easily operate the system even when their hands are occupied.

[0035] After activating the exterior camera function, users can personalize the settings, including: Photo countdown time: The default setting is 8 seconds, which users can adjust to a range of 5-30 seconds as needed. The photo countdown time refers to the time interval between completing the pose guidance and the actual photo taking, giving users sufficient preparation time. The system will intelligently adjust the default value based on the number of people and the complexity of the scene; for example, it will automatically extend the countdown when there are many people.

[0036] Number of people taking photos: Users can pre-specify the number of people participating in the photo shoot, and the system will optimize the recommended seating positions accordingly. If the user does not specify, the system will detect and count the actual number of people in real time through images of the external environment. The number of people detection is based on computer vision-based human detection and tracking algorithms, which can accurately identify the number of individuals in the images of the external environment.

[0037] Shooting direction: Five options are provided: front, rear, left, right, and panoramic. The default setting is "front". In non-panoramic mode, the system uses one, two, or three cameras to shoot; in panoramic mode, all external cameras work together to capture multi-angle photos and stitch them into a panoramic image. The actual available shooting directions depend on the user's personalized settings.

[0038] Before activating the license plate camera function, an automatic safety check will be performed to ensure the vehicle is parked (e.g., in Park with the handbrake engaged) to prevent accidental activation while driving. It will also check environmental conditions for suitable photography, such as whether the lighting is too dim or the weather is inclement, and provide corresponding prompts or suggestions.

[0039] Before the actual shooting, an intelligent analysis process is executed to generate personalized shooting suggestions. This process begins with environmental perception: the exterior cameras in a specified direction capture photos or videos of the surrounding environment, which are used as input data for analysis. The exterior environment images need to cover a sufficient field of view to ensure that the entire photographer and background environment are captured. The exterior environment images are first sent to the image processing unit for preprocessing, including noise reduction, color enhancement, and perspective correction, to improve image quality for subsequent analysis. The processed images are then fed into a large AI model for deep analysis. The AI ​​analysis includes the following key steps: Scene understanding: The model identifies key elements in the environment, such as natural features (trees, mountains, water, buildings, etc.), lighting conditions, color distribution, and spatial structure. Based on this information, the model determines the scene type (such as pastoral, urban, seaside, etc.) and aesthetic characteristics (such as symmetry, leading lines, framing elements, etc.), providing a basis for composition recommendations.

[0040] People analysis: The model detects the location of people in an image, counts the number of people, and estimates individual size and relative position. For multi-person scenes, the model also analyzes the relationships between people (such as family, friends, colleagues, etc.), infers group dynamics based on body language and interaction patterns, and recommends more natural standing arrangements.

[0041] Aesthetic Assessment: The model combines scene and subject information to evaluate the aesthetic potential of different composition schemes. This includes applying classic photographic composition rules such as the rule of thirds, symmetrical composition, and leading lines, while also considering factors such as light direction, background simplicity, and visual balance.

[0042] Based on the analysis results, the AI ​​model generates personalized photo suggestions, including: photo poses and shooting positions.

[0043] Photo positioning: Assign an ideal position to each person taking the photo, considering factors such as height (taller people should be placed in the back), relationship (closer people should be placed closer), and background harmony (avoid heads overlapping with background distractions). Recommended positioning ensures that each person is clearly visible and the overall composition is balanced and harmonious.

[0044] Posing Tips: We recommend suitable body postures and movements for each person being photographed, such as standing poses, gestures, and interaction methods. We suggest considering the characteristics of the scene (e.g., relaxed poses in natural environments) and the characteristics of the person (e.g., lively movements for children), and avoiding unnatural or awkward poses. There is a one-to-one correspondence between photographic positions and poses; each photographic position corresponds to one pose to guide the person standing at that position in posing accordingly.

[0045] Shooting parameters: We recommend optimal shooting settings, such as focus, exposure, and white balance, to ensure excellent final photo quality. However, these shooting parameters are adjusted directly by the camera during the shooting process according to the scene and do not need to be displayed through a projection light, so they are not considered as basic data for guiding out-of-vehicle photography.

[0046] Step 102: Determine the projection content based on the photo pose, photo position, and photo prompts, and determine the projection position of the projection content in the external environment based on the photo position.

[0047] In practice, after determining the photo-taking position and pose, this information needs to be projected to the user to provide guidance. Projection relies on an external vehicle projection module, which serves as the system's interface, visually presenting the photo-taking pose and position to the user. The vehicle's projection lights can employ high-resolution digital light processing or laser projection technology, capable of projecting clear patterns and text onto the ground or other flat surfaces. These projection lights are typically installed at the front of the vehicle, with some high-end models also equipped with auxiliary projection modules at the rear and sides to expand the projection range. The core technology of the projection lights lies in micromirror arrays and high-brightness light sources. Micromirror arrays consist of hundreds of thousands or even millions of micron-sized mirrors, each capable of independent deflection, forming an image by controlling the direction of light reflection. The light source typically uses high-lumen LEDs or laser diodes to ensure clear projection even during the day. Advanced projection systems also feature automatic brightness adjustment, dynamically adjusting the projection brightness according to ambient lighting conditions to maintain visibility while reducing energy consumption.

[0048] In the vehicle's external photography function, the projector light is primarily responsible for projecting three types of content: photo poses, photo positioning, and photo prompts. The photo prompts guide users through the start and end of the photo-taking process. This includes a countdown timer, an end indicator (e.g., "END"), and a prompt asking whether to continue taking photos (e.g., projecting "Continue Taking Photos" and "End Taking Photos" onto the ground). Photo positioning instructions typically use symbolic markers (such as circles, letters, numbers, or a small O-shaped figure) to clearly indicate the projection position for each subject. Photo poses are presented as simple drawings or icons showcasing recommended body postures and key movements. The countdown timer in the photo prompts visually displays the remaining time, helping users prepare. The projection system employs an intelligent obstacle avoidance algorithm to ensure that the projected content does not overlap with ground obstacles and optimizes the positioning layout based on the photo positioning to avoid overcrowding. Then, based on the photo positioning, the system determines the projection location of the content in the external environment and projects the content to that location, thus visualizing the photo-taking guidance.

[0049] Step 103: Project the content onto the projection position, and take a photo after the shooting conditions are met to obtain the initial photo. Then, perform post-processing on the initial photo according to the shooting mode to obtain the output photo.

[0050] In practice, after receiving the projected content and position, the projector lamp converts it into a visual projection displayed on the ground or other suitable surface. The projection system employs adaptive mapping technology, first acquiring the geometric features and texture information of the projection surface through a camera, and then automatically adjusting the projection angle and distortion correction to ensure that the indicator pattern is clearly visible and undistorted.

[0051] Photo positions are projected onto the designated areas using symbolic markers such as circles, letters, numbers, or head outlines. The system employs an intelligent layout algorithm that automatically adjusts the spacing and size of the markers based on the number of people and the size of the space, ensuring that the positions are evenly distributed and do not overlap with environmental obstacles. For multi-person scenes, the markers also consider relationships between people, such as placing children between parents in a family photo.

[0052] When photographing poses, it's recommended to project simple line drawings or icons to dynamically demonstrate body posture, hand and foot positions, and facial orientation. Complex poses will be demonstrated step-by-step to help users easily understand and imitate them. The projection system will ensure that the pose illustrations do not overlap with positioning markers while maintaining sufficient relevance for user reference.

[0053] The countdown timer for taking photos is displayed in large font and is usually placed in a position that is easily visible but does not interfere with the user's shooting position or pose. The countdown numbers may change color (e.g., from green to red) or size over time to enhance the visual perception of the passage of time and remind the user to get ready.

[0054] Since most vehicles currently have their projection lights mounted at the front, the system will adaptively adjust the interaction method when the user selects a "rear / left / right" shooting direction. In these modes, the system may not project the user's position (as the position may be outside the projection range), but instead will focus on projecting a diagram of the shooting posture and a countdown timer. Furthermore, the system can capture the user's gestures to select a position using the vehicle's side cameras, or guide the user to a suitable position using audio prompts.

[0055] Safety is also considered during projection to ensure that the projected content does not obstruct potential hazards (such as steps or obstacles) or excessively distract the user. In low-light environments, the system may automatically reduce the projection brightness to avoid glare.

[0056] In some embodiments, after the shooting conditions are met, a photo is taken to obtain an initial photo, including: Determine the current countdown number based on the photo-taking prompts; In response to the current timer value being zero, it is determined that the shooting conditions are met, and the vehicle-mounted camera is controlled to take a picture to obtain the initial photo.

[0057] In practice, the countdown timer displayed for taking a photo is used as the condition for initiating the photo-taking action. The current countdown number is determined based on the countdown data in the photo-taking prompt. When the current countdown number reaches zero, the countdown is considered complete, the shooting conditions are met, and the photo-taking operation is automatically triggered. Depending on the shooting mode selected by the user, the vehicle-mounted camera is controlled to execute different shooting strategies.

[0058] In some embodiments, post-processing is performed on the initial photo according to the shooting mode to obtain an output photo, including: In response to whether the shooting mode is panorama mode or multi-directional mode, the initial photo is stitched and beautified to obtain the output photo; In response to the shooting mode being unidirectional, the initial photo is beautified to obtain the output photo.

[0059] In practice, when the shooting mode is unidirectional, it means the user selects one of the forward, backward, left, or right directions, or does not select a direction (in which case the default projection direction is the shooting direction), activating the external camera in the corresponding direction to take a picture. The camera uses a high-speed continuous shooting mode (e.g., 10-15 frames per second) to capture multiple photos continuously, selecting the clearest one with the best expression as the initial photo. This mode is suitable for shooting needs that emphasize a specific angle or subject.

[0060] When the shooting mode is either panoramic or multi-directional. For panoramic mode: When the user selects panoramic mode, all external cameras are simultaneously triggered to capture scene images from multiple angles. Subsequently, the photo processing unit executes a real-time stitching process, combining multiple photos into a seamless panoramic image to obtain the initial photo. The stitching process includes multiple steps such as feature point detection, image registration, geometric correction, color equalization, and fusion processing to ensure natural and seamless seams.

[0061] For multi-directional mode, the external cameras in the corresponding directions are triggered simultaneously to capture scene images from multiple angles. Subsequently, the image processing unit executes a real-time stitching process, combining multiple photos into a seamless composite image to obtain the initial image. The stitching process includes multiple steps such as feature point detection, image registration, geometric correction, color equalization, and fusion processing to ensure natural and seamless seams.

[0062] The photo processing unit is responsible for computationally intensive processing of image data. It is typically integrated into the vehicle's cockpit domain controller, relying on the controller's high-performance computing resources (such as CPU, GPU, and NPU). The photo processing unit includes several dedicated processing modules, such as an image signal processing (ISP) module, a stitching and fusion module, and an optimization and enhancement module. The image signal processing module performs preprocessing operations, including depigmentation, noise reduction, color correction, white balance adjustment, and dynamic range optimization. These processing steps aim to correct various distortions and noise introduced during image acquisition, improving image quality. The stitching and fusion module is specifically designed for panoramic or multi-directional shooting modes, seamlessly combining images captured by multiple cameras into a single wide-angle photograph. This process involves complex algorithms such as feature point detection, image registration, geometric correction, and color equalization to ensure a natural and seamless stitching.

[0063] The optimization and enhancement module applies computational photography techniques such as HDR compositing, super-resolution, background blurring, and beautification to further enhance the artistic effect and technical quality of photos. These processes are applied not only to the final image but also to the analysis of images in the pre-processing stage, providing high-quality input data for AI recommendations. The photo processing unit also manages image compression and storage, supporting multiple formats (such as JPEG and RAW) and resolution options to meet different user quality needs and usage scenarios.

[0064] After shooting, the image data is sent to the photo processing unit for post-processing optimization, including digital image stabilization (correcting minor shake), HDR enhancement (expanding dynamic range), face optimization (beautification, red-eye correction), and intelligent cropping (optimizing composition). Scene-specific enhancement algorithms are also applied, such as enhancing color saturation in landscape mode and optimizing skin tone and background blur in portrait mode.

[0065] Post-processed photos are stored in high-quality formats (such as JPEG or RAW) in a dedicated storage area on the cockpit domain controller, automatically categorized by date, location, or scene type. Multiple export and sharing options are provided; users can export to external storage devices via USB or send photos to mobile phones wirelessly (such as Wi-Fi or Bluetooth). Some systems also support automatic cloud backup and sharing, allowing users to directly upload photos to personal cloud storage or social media platforms.

[0066] Furthermore, after a shooting session, users can choose to continue taking photos or end the process. After each shot, an interactive decision-making phase begins, asking the user whether to continue taking photos or end the session. The projector displays two options on the ground: "Continue Taking Photos" and "End Taking Photos," with "End Taking Photos" selected by default to optimize energy consumption. Users express their preference by choosing their position within the projection area of ​​the corresponding option.

[0067] A front-facing camera outside the vehicle captures the user's position, and the image processing unit uses computer vision algorithms (such as object detection and pose estimation) to recognize the user's selection. Selection recognition is based on pose analysis and position tracking to ensure accurate interpretation of the user's intent. The system provides clear visual feedback, such as highlighting the selected option, to avoid accidental operations.

[0068] If the user chooses to continue taking photos, new projection content and positions will be generated to avoid repetition with the previous round. This can be achieved by adjusting the standing layout, recommending different poses, or changing the shooting angle. These diverse strategies enrich the photo collection and provide users with more choices. The system supports batch processing, allowing users to preset the number of consecutive shots and automatically perform multiple shots with different settings.

[0069] If the user chooses to end the session or the system detects a timeout due to inactivity, the projection will automatically shut down and enter standby mode, providing feedback through flashing headlights or a short beep. Users can review all photos on the in-vehicle infotainment screen or a mobile app, allowing them to filter, edit, or share them. The system may integrate a smart album function, automatically selecting the best photos, generating collections, or short videos to enhance the user experience.

[0070] The vehicle exterior photography control method provided in this application embodiment senses the external environment through external environmental images. Under the selected shooting mode, it recommends the most suitable shooting posture and position for the user, ensuring that the photos best suit the external environment. The shooting posture and position need to be output via projection. Therefore, the projection position of the content in the external environment needs to be determined based on the shooting position, and the projection content to be projected is determined based on the shooting posture, shooting position, and shooting prompts. This guides the user in positioning and posing. After projection is complete and shooting conditions are met, the camera takes a picture of the prepared user and processes the photo according to the shooting mode to obtain a photo that meets the user's needs. This satisfies the user's requirement to take photos of specific locations without third-party assistance, thereby improving the user experience and enhancing the vehicle's intelligence. In other words, the vehicle exterior photography control method provided in this application embodiment has the following technical effects: Multimodal interaction integration: The system combines touch, voice, and mobile interaction methods to adapt to user operating preferences in different scenarios. Projection interaction provides intuitive visual guidance, reducing the learning cost and making it easy for users of all ages to use.

[0071] Artificial intelligence-driven: The recommendation engine, based on a large AI model, equips the system with professional photography knowledge, enabling it to generate personalized suggestions based on specific scenes and subject characteristics, significantly improving the quality of finished photos. A continuous learning mechanism allows the system to constantly adapt to user preferences, providing increasingly accurate services.

[0072] Automated workflow: The entire process, from environmental awareness to final image output, is highly automated, allowing users to achieve a professional-grade photography experience with simple selections. Intelligent composition, shooting, and processing reduce the user's workload, enabling them to focus more on enjoying the moment itself.

[0073] System resource integration: Make full use of the vehicle's existing sensors and computing resources, such as surround view cameras, cockpit domain controllers and projection lights, to achieve added functionality without the need for a large amount of dedicated hardware, thereby reducing system cost and complexity.

[0074] Scene adaptability: The system takes into account various real-world usage scenarios, such as different numbers of people, different shooting directions, and different environmental conditions. It adapts to different needs through intelligent algorithms to ensure a high-quality experience in all situations.

[0075] In some embodiments, such as Figure 2 As shown, the shooting position and corresponding shooting posture are determined based on the external environment image and shooting mode, including: Step 201: Determine the number of people taking photos and the type of environment based on the images of the external environment.

[0076] In practice, users set the number of people to be photographed via the central control screen or a mobile phone linked to the vehicle's infotainment system. When setting the number of people, the system uses real-time external environmental images to detect the actual number of people within the photographing range as a recommended number, thus optimizing the recommended seating arrangement. If the user does not set the number of people to be photographed, the system uses real-time external environmental images to detect and count the actual number of people. The people detection is based on computer vision-based human detection and tracking algorithms, which can accurately identify the number of individuals taking photos in the frame.

[0077] Step 202: Determine the shooting direction based on the shooting mode.

[0078] In some embodiments, determining the shooting direction based on the shooting mode includes: In response to the shooting mode being set to panoramic shooting, all directions are determined as the shooting direction; In response to the shooting mode being non-panoramic and the user making a selection operation, the selected direction corresponding to the user's selection operation is determined as the shooting direction. In response to the shooting mode being non-panoramic and the absence of user selection, the projection direction of the projector lamp is determined as the shooting direction.

[0079] In practice, the panoramic mode includes all shooting directions; the one-way mode includes the single direction selected by the user; and the multi-way mode includes two or three directions selected by the user. If the user does not make a personalized selection, the direction of the projector light will be used as the shooting direction.

[0080] Step 203: In response to the existence of a first shooting direction that is the same as the projection direction of the projector, determine the shooting position and corresponding shooting posture according to the number of people taking pictures and the type of environment.

[0081] In practice, since the vehicle projection light is integrated into the vehicle's headlights, direct visual guidance on the shooting position can only be provided if there is a first shooting direction that corresponds to the projection direction of the projection light. Otherwise, only guidance on the shooting posture can be provided.

[0082] Step 204: In response to the absence of a first shooting direction in the shooting directions, mark the shooting position as empty, and determine the shooting posture according to the number of people taking photos and the type of environment.

[0083] In practice, since the vehicle projection light is integrated into the vehicle's headlights, direct visual guidance on the shooting position can only be provided if there is a first shooting direction that corresponds to the projection direction of the projection light. If there is no first shooting direction, the shooting position cannot be directly projected onto the user's standing position. Instead, the shooting position and background can be integrated into the shooting posture, providing partial positioning guidance information when guiding the shooting posture.

[0084] In some embodiments, determining the shooting position and corresponding shooting pose based on the number of people taking photos and the type of environment includes: Determine the initial recommended location for taking photos from the external environment image based on the environment type; The initial recommended locations are filtered based on their priority and the number of people taking photos to obtain recommended image locations; Based on the recommended image location and the body shape data of each photographer, the recommended pose and standing position for each photographer are determined. The recommended poses of the photographers are integrated to obtain the shooting pose, and the standing positions of the photographers are integrated to obtain the shooting position.

[0085] In practice, suitable initial recommended locations for taking photos are determined based on different external environments, such as under trees or next to rocks. The priority of each initial recommended location is determined based on its suitability to the environment. Then, the maximum number of people that can stand at each recommended location is determined based on its size and style. During the filtering process, initial recommended locations with a maximum standing capacity less than the number of people taking photos are first eliminated. Then, the remaining initial recommended locations are sorted according to priority to obtain a location sequence. Recommended locations are then made based on this location sequence. If the user is not satisfied, recommended locations are made sequentially according to the location sequence to meet the user's personalized needs.

[0086] When recommending photo positions, an ideal standing position needs to be specified for each photographer. Factors to consider when integrating these positions include each photographer's body shape data, such as height (taller individuals should be placed further back), the closeness of the relationship (closer individuals should be placed closer), and background harmony (avoiding overlap between the head and background distractions). The integration process must ensure that each photographer is clearly visible and that the overall composition is balanced and harmonious.

[0087] When suggesting poses for photos, it's necessary to recommend suitable user-recommended poses for each photographer based on their body shape data, such as standing postures, gestures, and interaction methods. When integrating user-recommended poses, it's essential to consider scene characteristics (e.g., recommending relaxed poses in natural environments) and individual characteristics (e.g., recommending lively movements for children) to avoid unnatural or awkward poses.

[0088] Optionally, the process of determining the shooting positions and corresponding poses based on the number of people taking photos and the type of environment can be handled by an AI big data model to reduce the occupation of vehicle resources. The AI ​​big data model is responsible for analyzing external environmental images and generating personalized shooting suggestions. The AI ​​big data model is usually deployed in an edge-cloud collaborative manner. The basic model is stored in the cloud, and the inference model, which is distilled and compressed, is deployed on the vehicle to adapt to the memory and computing power limitations of the in-vehicle environment. Based on advanced computer vision and deep learning technologies, the AI ​​big data model can understand visual elements and semantic information in complex scenes. The training data of the AI ​​big data model includes a large number of labeled scene images and portrait photos, covering different environmental types (such as natural scenery, urban street scenes, historical buildings, etc.), different lighting conditions (such as daytime, nighttime, golden hour, etc.), and different personnel configurations (such as individuals, groups, families, teams, etc.).

[0089] Through deep learning, the AI ​​model has learned the complex relationships between composition aesthetics, pose evaluation, and scene adaptability, enabling it to generate reasonable shooting positions and poses based on the features of the input image. During the inference phase, the AI ​​model performs multiple analysis tasks: scene classification (identifying environment types such as beaches, forests, and cities), person detection (locating and identifying people in images), attribute analysis (estimating people's age, gender, clothing, etc.), and environmental assessment (analyzing lighting conditions, background complexity, etc.). Based on these analyses, the AI ​​model, combined with its built-in photography knowledge base (such as composition rules, pose libraries, and aesthetic principles), generates personalized shooting suggestions, including shooting positions, poses, and camera shooting parameters.

[0090] Large AI models also possess continuous learning capabilities, enabling them to constantly optimize recommendation strategies based on user feedback and choices. For example, if a user frequently selects a certain type of pose, the model will infer the user's preference and prioritize similar styles in subsequent recommendations. This adaptive mechanism allows the system to increasingly align with the user's personalized needs, enhancing the user experience.

[0091] In some embodiments, determining the projection position of the projected content in the external environment based on the camera's position includes: The location of the photo is matched with the actual location in the external environment, and the matched location is determined as the projection location.

[0092] In practice, the photo-taking position is a two-dimensional coordinate position in the projected coordinate system, and the projected position is a three-dimensional coordinate position in the three-dimensional coordinate system of the external environment. Similarity is calculated in the three-dimensional coordinate system based on the image recommendation position, and position matching is performed based on the magnitude of the similarity. The position point with the highest similarity in the three-dimensional coordinate system is determined as the actual position of the successful match, and this actual position is determined as the projected position corresponding to the image recommendation position.

[0093] When projecting based on the content and location, the projection lamp converts the received content and location into a visual projection displayed on the ground or other suitable surface. The projection system employs adaptive mapping technology, first acquiring the geometric features and texture information of the projection surface via a camera, then automatically adjusting the projection angle and distortion correction to ensure that the indicator pattern is clearly visible and undistorted.

[0094] Photo positions are projected onto the designated areas using symbolic markers such as circles, letters, numbers, or head outlines. The system employs an intelligent layout algorithm that automatically adjusts the spacing and size of the markers based on the number of people and the size of the space, ensuring that the positions are evenly distributed and do not overlap with environmental obstacles. For multi-person scenes, the markers also consider relationships between people, such as placing children between parents in a family photo.

[0095] When photographing, poses should be projected as simple line drawings or icons, dynamically demonstrating body posture, hand and foot positions, and facial orientation. Complex poses will be demonstrated step-by-step to help users easily understand and imitate them. The projection system will ensure that the projected pose illustrations do not overlap with positioning markers, while maintaining sufficient relevance for user reference.

[0096] The countdown timer for taking photos is displayed in large font and is usually placed in a position that is easily visible but does not interfere with the user's shooting position or pose. The countdown numbers may change color (e.g., from green to red) or size over time to enhance the visual perception of the passage of time and remind the user to get ready.

[0097] Safety is also considered during projection to ensure that the projected content does not obstruct potential hazards (such as steps or obstacles) or excessively distract the user. In low-light environments, the system may automatically reduce the projection brightness to avoid glare.

[0098] In some embodiments, such as Figure 3 As shown, the projected content is determined based on the photo pose, photo position, and photo prompts, including: Step 301: Arrange the position marks of each photographer according to their position.

[0099] In practice, if there are three people taking photos, three non-overlapping but identical position markers can be selected, such as three non-intersecting circles. Each user stands in their corresponding circle when taking the photo. The position marker is a shape with the photo-taking position as its geometric center. Alternatively, different icons can be chosen to represent different user positions, such as circles, squares, and triangles. This facilitates user guidance and avoids vague "go to that circle (in the scenario of three circles)" selections, instead providing precise "go to the triangle" selections. After determining the position markers, their positions need to be arranged according to the photo-taking positions. An intelligent layout algorithm automatically adjusts the spacing and size of the markers based on the number of people and the available space, ensuring that the positions are evenly distributed and do not overlap with environmental obstacles. For multi-person scenarios, the markers also consider relationships between people, such as placing children between parents in a family photo. For example, when taking photos in a "I" shape, the position markers are arranged in a "I" shape.

[0100] Step 302: Arrange the photo poses corresponding to the photo positions to the positions indicated by the preset arrangement direction.

[0101] In practice, there is a one-to-one correspondence between the photo-taking position and the photo-taking pose. Each photo-taking position corresponds to a photo-taking pose, in order to guide the photographer standing at the photo-taking position to strike the corresponding pose and to ensure that users at the photo-taking position can be accurately guided to imitate the photo-taking pose in multi-person scenarios.

[0102] The preset arrangement direction can be the direction closest to the vehicle, that is, the shooting posture is projected onto the side of the shooting position closest to the vehicle, so that the user can see the shooting posture when facing the vehicle, thus achieving effective shooting guidance.

[0103] The photo poses are projected as simple line drawings or icons, dynamically demonstrating body posture, hand and foot positions, and facial orientation. Complex poses are demonstrated step-by-step to help users easily understand and imitate them. The projection system ensures that the pose illustrations do not overlap with the positioning markers, while maintaining sufficient relevance for user reference.

[0104] Step 303: Arrange the photo prompts in a position that does not overlap with the photo pose and position markings to obtain the projected content.

[0105] In practice, the photo-taking prompt is displayed as a countdown timer projected onto the screen. The projection uses a large font and is typically placed in an easily accessible location that does not interfere with the positioning markers or the user's projection posture. The countdown numbers may change color (e.g., from green to red) or size over time to enhance the visual perception of time passing and remind the user to prepare.
