Description

Technical Field

[0001] This application relates to the technical field of vehicle-mounted cameras, and particularly to a method for sharing cross-vehicle camera data and related devices. Background Art

[0002] Existing vehicle-mounted cameras are mainly used for the perception of the vehicle's own environment or the function of driving record. The camera data is only limited to the use of the vehicle itself, lacking a collaborative sharing mechanism between vehicles. Some technologies attempt to share camera images through the cloud, but there are risks of privacy leakage and require complex manual authorization processes. In addition, existing solutions cannot achieve dynamic real-time interaction between vehicles, and it is difficult for users to conveniently call the camera resources of other vehicles.

[0003] Therefore, it is necessary to propose a cross-vehicle camera sharing method to solve the problem that cross-vehicle camera sharing cannot be conveniently achieved in the prior art. Summary of the Invention

[0004] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description section. The Summary of the Invention section of this application does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0019] In a feasible implementation manner, the method for sharing cross-vehicle camera data further includes:

[0020] Send a shooting operation instruction from the self-vehicle to the target vehicle, where the shooting operation instruction includes media type, shooting duration, and resolution requirements;

[0021] After the target vehicle responds to the shooting operation instruction and performs shooting, control the target vehicle to encrypt the camera data in blocks and upload it to the cloud server, so that the self-vehicle downloads and stores the camera data from the cloud server.

[0022] In a feasible implementation manner, the method for sharing cross-vehicle camera data further includes:

[0023] If the camera of the target vehicle is occupied, add the shooting operation instruction to the waiting queue or execute it downgraded; the downgraded execution includes shortening the shooting duration or reducing the resolution requirements;

[0024] If the storage space of the target vehicle is insufficient, terminate the camera shooting of the target vehicle and send a termination shooting information to the self-vehicle, so that the self-vehicle issues a termination shooting prompt signal based on the termination shooting information.

[0025] In a feasible implementation manner, the method for sharing cross-vehicle camera data further includes:

[0026] When the transmission of the camera data is interrupted, cache the camera data within a preset time before the interruption.

[0043] Please refer to Figure 1 , which is a schematic flowchart of a method for sharing cross-vehicle camera data provided by an embodiment of the present application, and specifically may include:

[0044] S110. Determine the same-brand vehicles around the host vehicle based on the real-time image data of the vehicles around the host vehicle.

[0045] Exemplarily, images of surrounding vehicles are collected by the surround-view cameras (front / rear / sides) of the host vehicle at a rate of 10 frames per second, and are preprocessed in real time (distortion removal, brightness equalization) by the in-vehicle graphics processor. By finding vehicles of the same brand based on the real-time image data of the surrounding vehicles of the host vehicle, suitable targets can be screened for subsequent data sharing.

[0046] S120. In the case of receiving an instruction from the user to select a target vehicle from vehicles of the same brand, send an authorization request to the target vehicle, where the authorization request includes the identity information of the host vehicle.

[0047] Exemplarily, after the user selects a target vehicle from these vehicles of the same brand, an authorization request containing the identity information of the host vehicle is generated and sent to the target vehicle, which ensures that data sharing is carried out on the premise of mutual recognition.

[0048] S130. Receive the confirmation information generated based on the authorization request returned by the target vehicle, and establish a temporary access link based on the confirmation information.

[0049] Exemplarily, after receiving the authorization request, the target vehicle pops up an authorization prompt interface on the central control screen, displaying the model icon, position distance, and permission scope of the host vehicle; the owner of the target vehicle completes the confirmation through a voice command (such as "agree to authorize") or biometric identification (fingerprint / face recognition), and then generates an authorization token (i.e., the confirmation information of the authorization request) and transmits it back to the host vehicle. The host vehicle receives the authorization confirmation information returned by the target vehicle and establishes a temporary access link based on this.

[0050] S140. Obtain the camera data of the target vehicle through the temporary access link.

[0051] Exemplarily, after shooting, the target vehicle encrypts the camera data in chunks and uploads it to the cloud server through the cellular network (5G / 4G); after the host vehicle downloads the file from the cloud, it automatically associates the timestamp, location coordinates, and relative position information of the two vehicles, and stores them in the local "cross-vehicle media library" directory, supporting retrieval by timeline or geographical location.

[0052] In summary, by identifying vehicles of the same brand through image recognition, the screening of trusted devices is achieved. Only vehicles of the same brand are likely to participate in data sharing, reducing the risk of illegal access. At the same time, an authorization mechanism is introduced to ensure the legality and security of data sharing. Only after the target vehicle confirms the authorization can the host vehicle obtain its camera data.

[0053] In some examples, based on the real-time image data of the surrounding vehicles of the host vehicle, determining the vehicles of the same brand around the host vehicle includes:

[0054] Based on the real-time image data of the surrounding vehicles of the host vehicle, extracting the vehicle brand features of the surrounding vehicles of the host vehicle;

[0055] Input the vehicle brand features into a preset brand feature recognition model for brand classification to obtain a classification confidence level.

[0056] Determine the vehicles corresponding to the vehicle brand features with a classification confidence level exceeding a preset threshold as vehicles of the same brand.

[0057] Exemplarily, first extract vehicle brand features from real-time image data, such as vehicle logos, intake grilles, taillight designs, etc. Then input these features into a preset brand feature recognition model for brand classification to obtain a classification confidence level. Finally, determine the vehicles with a classification confidence level exceeding a preset threshold (such as 90%) as vehicles of the same brand.

[0058] Furthermore, by using a pre-trained brand feature recognition model and a classification confidence level threshold, the accuracy and reliability of identifying vehicles of the same brand are improved. Only vehicles with a sufficiently high classification confidence level will be determined as vehicles of the same brand, reducing the possibility of misjudgment and providing a more accurate basis for subsequent authorization and data sharing.

[0059] In some examples, the authorization request includes at least one of the unique identifier of the vehicle itself, digital certificate, request permission type, and permission validity period.

[0060] Exemplarily, the specific information included in the authorization request includes: the hash value of the unique identifier of the vehicle itself (such as the hash value of the vehicle identification number (VIN)), digital certificate (issued by the vehicle brand certification center), request permission type (such as "real-time camera access" or "single shot"), and permission validity period (default 5 minutes, which can be adjusted manually by the user). This information helps the target vehicle accurately understand the identity of the vehicle itself and the scope of the requested permissions.

[0061] Furthermore, by specifying the content of the authorization request in detail, the authorization process becomes more standardized and transparent. The digital certificate guarantees the authenticity and legality of the identity of the vehicle itself, and the settings of the permission type and validity period enable the target vehicle user to better control the scope and time of data sharing, further protecting the privacy and data security of the user.

[0062] In some examples, obtain the camera data of the target vehicle through a temporary access link, including:

[0063] Obtain the initial camera data of the target vehicle in real time through the temporary access link;

[0064] Adjust the images in the initial camera data based on the current network quality and perform privacy information masking processing on the images to obtain the camera data.

[0065] Exemplarily, the host vehicle establishes a temporary access link with the target vehicle for connection, uses a low-latency video transmission protocol to transmit the camera data stream, and supports H.265 encoding to reduce bandwidth occupancy.

[0066] Specifically, first, the initial camera data of the target vehicle is obtained in real time through the temporary access link, and then the images in the initial camera data are adjusted according to the current network quality, such as dynamically adjusting the resolution and frame rate to ensure the smoothness of the images. At the same time, the privacy information in the images (such as the faces or license plate information of the passengers inside the target vehicle) is masked to obtain the final camera data.

[0067] Furthermore, dynamically adjusting the image parameters according to the network quality can ensure the smoothness of the camera data transmission in different network environments and improve the user experience. Masking the privacy information effectively protects the privacy of the target vehicle and avoids the risk of privacy leakage. As Figure 2 shown, for the identified vehicles of the same brand, the license plate area (if visible) is extracted and locally blurred to protect privacy, and only the vehicle model information is retained for interface display. On the map interface of the central control screen, the vehicles of the same brand around the host vehicle and the operation menu identified are marked in the form of 3D icons, and the icon colors distinguish the vehicle status (such as green for connectable and gray for offline). The host vehicle user can also select different cameras of the target vehicle (such as the front driving recorder and the rear wide-angle camera) through the pull-down menu of the central control screen, and the system sends a camera switching instruction to the target vehicle.

[0068] In some examples, the method for sharing cross-vehicle camera data further includes:

[0069] Sending a shooting operation instruction from the host vehicle to the target vehicle, where the shooting operation instruction includes the media type, shooting duration, and resolution requirements;

[0070] After the target vehicle responds to the shooting operation instruction and performs shooting, controlling the target vehicle to encrypt the camera data in blocks and upload it to the cloud server, so that the host vehicle can download and store the camera data from the cloud server.

[0071] Exemplarily, the host vehicle sends a user operation instruction containing information such as the media type (photo or video), shooting duration (15 seconds by default for video), and resolution requirements (4K by default) to the target vehicle. After the target vehicle responds to the instruction and performs shooting, it encrypts the camera data in blocks and uploads it to the cloud server, and then the host vehicle downloads and stores this data from the cloud server.

[0072] Furthermore, the user can control the target vehicle to take pictures according to their own needs, generating diverse media content and realizing cross-vehicle perspective co-creation of media content. The camera data is encrypted and uploaded to the cloud server in chunks, ensuring the security of camera data transmission. At the same time, it is convenient for the host vehicle to download and store, facilitating subsequent viewing and management.

[0073] In some examples, the method for sharing cross-vehicle camera data further includes:

[0074] If the camera of the target vehicle is occupied, the shooting operation instruction is added to the waiting queue or degraded; the degraded execution includes shortening the shooting duration or reducing the resolution requirement;

[0075] If the storage space of the target vehicle is insufficient, the camera shooting of the target vehicle is terminated and a termination shooting message is sent to the host vehicle, so that the host vehicle issues a termination shooting prompt signal based on the termination shooting message.

[0076] Exemplarily, after receiving the user operation instruction, the target vehicle calls the specified camera to perform shooting. If the camera of the target vehicle is occupied (such as when the advanced driver assistance system function is being executed), an error code is returned and the host vehicle user is prompted. At the same time, the user operation instruction is added to the waiting queue or degraded (such as shortening the shooting duration or reducing the resolution requirement). If the storage space of the target vehicle is insufficient, the camera shooting is terminated and the host vehicle user is notified.

[0077] During video recording, the in-vehicle system of the target vehicle continuously monitors the storage space. If the remaining space is less than 10%, the recording is automatically terminated and the host vehicle is notified.

[0078] Through resource priority management, it is ensured that the original safety and functions of the target vehicle are not affected. When the camera is occupied, the method of waiting or degraded execution is adopted, which not only ensures that the remote shooting request can be processed, but also does not interfere with the normal operation of the target vehicle. When the storage space is insufficient, the shooting is terminated in time and the host vehicle user is notified, avoiding data loss or shooting failure caused by storage space problems.

[0079] In some examples, the method for sharing cross-vehicle camera data further includes:

[0080] When the camera data transmission is interrupted, the camera data within a preset time before the interruption is cached.

[0081] Exemplarily, for the situation of camera data transmission interruption, it is stipulated that when the camera data transmission is interrupted, an automatic attempt is made to re - establish the connection (up to 3 times), and at the same time, the camera data within a preset time (such as 5 seconds) before the interruption is cached. Caching the camera data before the interruption provides a basis for the recovery of camera data transmission, enables the continuous transmission of camera data after the connection is re - established, reduces the loss of camera data, ensures the integrity and continuity of camera data, and improves the user experience.

[0082] In summary, a method for sharing cross - vehicle camera data provided by this application, in terms of security and privacy protection, image recognition filters out vehicles of the same brand to reduce the risk of illegal access, the dynamic authorization mechanism allows users to independently control permissions, and real - time coding of privacy information in the video stream and default hiding of geographical locations in the uploaded files ensure privacy. In terms of functions and interactivity, it breaks through traditional limitations to achieve co - creation of media content from a cross - vehicle perspective, is applicable to scenarios such as convoy following, and also enhances the social function of vehicles through social interaction, and can automatically request surrounding vehicles to take pictures to provide evidence for claims in case of accidents. In terms of system performance and compatibility, low - bandwidth coding and dynamic adjustment of resolution and frame rate are adopted to ensure smooth data transmission, the low - coupling design interacts with the original modules through standardized application programming interfaces to be compatible with different vehicle models, and supports cross - platform synchronization and editing of media files. In terms of resource management, resource priorities are reasonably managed, when the camera is occupied, the shooting request waits or is downgraded for execution, and when the data transmission is interrupted, it automatically reconnects and caches data to ensure integrity.

[0083] The technical solution of this application will be further described in detail through specific embodiments below.

[0084] Step 1: When the user is driving vehicle A, the in - vehicle camera recognizes vehicle B of the same brand, and the icon of vehicle B is displayed on the map interface of the central control screen.

[0085] Step 2: The user clicks on the icon of vehicle B and selects "Request camera permission". The system generates a request packet containing the digital certificate of vehicle A and sends it to vehicle B through the vehicle - to - external communication channel.

[0086] Step Ⅲ: The owner of vehicle B confirms the authorization through a pop - up window on the in - vehicle screen, and the validity period of the permission is set to 10 minutes.

[0087] Step 4: After vehicle A receives the authorization response, it obtains the front - facing camera image of vehicle B and displays it on the right - hand split screen of the central control screen.

[0088] Step 5: The user of vehicle A clicks the "Shoot" button, vehicle B synchronously performs high - definition video recording, and after completion, encrypts and uploads the file to the cloud, and vehicle A automatically downloads and saves it in the local photo album.

[0089] In summary, the present application provides a safe and efficient method for sharing cross-vehicle camera data, which realizes the establishment of a trusted connection between vehicles of the same brand through image recognition, supports real-time viewing of the live video and generation of media content, and enhances the vehicle socialization function.

[0090] Furthermore, the present application can be applied to convoy following collaboration. That is, when multiple vehicles of the same brand form a convoy, the leading vehicle can simultaneously obtain the camera images of multiple following vehicles behind it and synthesize a multi-view panoramic video in real time for generating a documentary of the convoy's progress; accident scene recording. That is, when the vehicle itself has an accident, it automatically sends an emergency shooting request to surrounding vehicles of the same brand to obtain a video of the accident process from a third-party perspective as evidence for insurance claims; social media interaction. That is, the user can actively publish a "can be photographed" status, allowing the owners of other vehicles of the same brand to initiate a shooting request during a specific time period (such as a car club activity) to generate an interactive short video.

[0091] It should be noted that the above embodiments are only the best examples and are not intended to limit the implementation manners of the present application.

[0092] Furthermore, the present application also proposes a cross-vehicle camera data sharing system, which is applied to the embodiments of any one of the above cross-vehicle camera data sharing methods, specifically as Figure 3 shown, which is a schematic diagram of the functional modules of a cross-vehicle camera data sharing system proposed by the present application, including:

[0093] An image recognition module 21, configured to determine the vehicles of the same brand around the vehicle itself based on the real-time image data of the vehicles around the vehicle itself;

[0094] A dynamic authorization module 22, configured to send an authorization request to the target vehicle when receiving an instruction from the user to select a target vehicle from the vehicles of the same brand, and the authorization request includes the identity information of the vehicle itself;

[0095] A communication module 23, configured to receive the confirmation information generated based on the authorization request returned by the target vehicle and establish a temporary access link based on the confirmation information;

[0096] A media generation and feedback module 24, configured to obtain the camera data of the target vehicle through the temporary access link.

[0097] Exemplarily, a camera access control module 25 is further included in the cross-vehicle camera data sharing system, configured to collect image data by controlling the in-vehicle camera.

[0098] The cross-vehicle camera data sharing system proposed by the present application interacts with the original camera module of the vehicle through a standardized application programming interface, without the need to modify the hardware, and is compatible with different generations of vehicle models. As Figure 3As shown in the figure, the cross-vehicle camera data sharing system of the host vehicle includes a camera access control module 25, an image recognition module 21, a dynamic authorization module 22, a media integration and feedback module 24, and a communication module 23. Among them, the image recognition module 21 transmits the recognized data to the image recognition module 31 of the other vehicle, and the communication module 23 is also connected to the communication module 33 of the other vehicle. The cross-vehicle camera data sharing system of the other vehicle includes a camera access control module 35, an image recognition module 31, a dynamic authorization module 32, a media integration and feedback module 34, and a communication module 33. Among them, the image recognition module 31 of the other vehicle transmits the recognized data to the image recognition module 21 of the host vehicle, and the communication module 33 of the other vehicle is also connected to the communication module 23 of the host vehicle. The host vehicle and the other vehicle communicate through a vehicle-to-outside communication channel to achieve data interaction and sharing.
