[0046] The purpose, features and advantages of this application will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an intelligent driving domain controller, etc. The following takes the intelligent driving domain controller as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the present application embodiment provides a method for collecting desensitized data, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the desensitized data collection method of the present application.

[0051] In this embodiment, the desensitized data collection method includes steps S10 to S40:

[0052] Step S10, when receiving the vehicle lock command, shutting down the internal process of the vehicle and disconnecting the communication channel of the vehicle to put the vehicle into an offline state;

[0053] It should be noted that when a vehicle lock command is received, it means that the vehicle has been locked by a key or an APP (Application), and at this time, the various controllers of the vehicle will gradually stop communicating. In this process, the intelligent driving domain controller will detect the application message sending status of other units. When it detects that other units no longer send application messages, it will kill various processes inside the vehicle and disconnect external communications, that is, shut down the vehicle's internal processes and disconnect the vehicle's communication channels to put the vehicle into an offline state. Specifically, the unit refers to the ECU (Electronic Control Unit) in the vehicle, which is responsible for different functions of the vehicle such as engine control, braking system, etc. Application messages refer to data information sent between these units through the vehicle bus system.

[0054] It should be understood that when the intelligent driving domain controller detects that data is no longer sent between ECUs, directly shutting down the vehicle's internal processes and putting the vehicle into an offline state can quickly release computing resources and reduce system load, so that the vehicle can quickly enter a desensitized data collection state and improve data collection efficiency.

[0055] In a feasible implementation, before step S10, it may include: when the vehicle is in a preset scene, obtaining a camera flag corresponding to the preset scene; based on the camera flag, controlling the corresponding vehicle-mounted camera to collect video data to obtain data to be desensitized.

[0056] It should be noted that the preset scene refers to the trigger scene for video recording set in the specific scene trigger preset on the vehicle side during the research and development stage of the vehicle, such as automatic emergency braking, vehicle collision, and abnormal exit of high-speed NOA (Navigate on Autopilot, navigation assisted driving), which may cause abnormal vehicle status data. In addition, due to the different field of view angles and resolutions of different on-board cameras, different on-board cameras need to be identified by camera flags. Specifically, the camera flags may include forward-looking flags, side-looking flags, and surround-looking flags, which are not limited in this embodiment.

[0057] In addition, it should be noted that during the driving process of the vehicle, the trigger module of the intelligent driving domain controller will monitor the vehicle's operating status data in real time. When the vehicle triggers an abnormal event, the trigger module will identify the preset scene of the vehicle from the operating status data, activate the corresponding scene trigger, obtain the camera flag corresponding to the scene trigger, and send the flag to the data recording module, so that the data recording module controls the corresponding on-board camera to record the data of the corresponding perspective according to the flag, and obtains the original video data corresponding to the preset scene, that is, the data to be desensitized. Specifically, NOA-type scene triggers mainly correspond to the collection of video data from the front-view camera and the side rear camera, and HPP (Home-zone Parking Pilot, memory parking assist) type triggers mainly correspond to the collection of video data from the surround-view camera.

[0058] It should be understood that after the data to be desensitized is obtained, the data to be desensitized will be saved in the vehicle's internal storage system, and the camera flag that recorded the data to be desensitized will be recorded.

[0059] Step S20, when the vehicle is in an offline state and the data to be desensitized is detected, desensitizing the data to be desensitized to obtain target data;

[0060] It should be noted that after the intelligent driving domain controller detects that the vehicle has entered an offline state, the state management module will be started to detect the state of the video data in the vehicle's internal storage system. When it is detected that there is recorded video data that has not been desensitized, the data is used as the data to be desensitized, the data to be desensitized is read and desensitized, and the desensitized video data, i.e., the target data, is obtained.

[0061] In a feasible implementation manner, when the vehicle is in an offline state and the data to be desensitized is detected, the step of desensitizing the data to be desensitized to obtain the target data in step S20 may include steps A11 to A12:

[0062] Step A11, when the vehicle is in an offline state and detects the data to be desensitized, obtaining the camera flag of the data to be desensitized;

[0063] It should be understood that desensitizing the data in an offline state can avoid processing a large amount of data during normal vehicle driving, which affects the performance of the intelligent driving system and ensures that the system focuses on the driving task. After the vehicle enters the offline state, the intelligent driving domain controller will be in the domain control idle period. At this time, the intelligent driving domain controller will start the desensitization process to desensitize the data. Since different scene data may be collected by different on-board cameras, the video data recorded by different on-board cameras have different fields of view and different resolutions. In order to ensure the accuracy of data desensitization, different desensitization methods are required for video data collected by different on-board cameras. Therefore, after detecting the data to be desensitized, before desensitizing the data, it is necessary to obtain the camera flag corresponding to the data to determine the on-board camera used to record the data.

[0064] Step A12: desensitize the data to be desensitized based on the camera flag to obtain target data.

[0065] It should be understood that after obtaining the camera flag corresponding to the data to be desensitized, the corresponding data desensitization method can be determined based on the camera flag, and the data to be desensitized can be desensitized based on the corresponding data desensitization method to obtain the desensitized data, that is, the target data.

[0066] In a feasible implementation, step A12 may include steps B11 to B12:

[0067] Step B11, acquiring a corresponding target detection model based on the camera flag;

[0068] It should be noted that different on-board cameras have different field of view angles and resolutions, and the corresponding target recognition models adopted in the process of data desensitization will also be different. Before the target recognition model is deployed to the vehicle-side software, its corresponding target recognition model will be trained based on the data characteristics collected by different on-board cameras. Specifically, the front face, side face, oblique face and blurred face, blue license plate, yellow card and green license plate of the front-view on-board camera are input, and large-scale training is carried out to obtain the front-view target detection model; the front face, side face, oblique face and blurred face, blue license plate, yellow card and green license plate of the side-view on-board camera are input, and large-scale training is carried out to obtain the side-view target detection model; the front face, side face, oblique face and blurred face, blue license plate, yellow card and green license plate of the surround-view on-board camera are input, and large-scale training is carried out to obtain the surround-view target detection model.

[0069] Step B12: identifying the sensitive information area of ​​the data to be desensitized based on the target detection model, and desensitizing the data to be desensitized in the sensitive information area to obtain target data.

[0070] It should be understood that after the target detection model corresponding to the data to be desensitized is determined based on the camera flag, the sensitive information in the data to be desensitized, such as face and license plate information, will be identified based on the target detection model, and the area where the sensitive information is located, i.e., the sensitive information area, will be output to desensitize the data to be desensitized in the sensitive information area, and obtain the desensitized video data, i.e., the target data. Specifically, the sensitive information area will be determined by the coordinate value of the corresponding frame image of the sensitive information in the data to be desensitized. After obtaining the coordinate value, the original camera image corresponding to the corresponding frame in the data to be desensitized can be irreversibly mosaiced according to the coordinate value to cover or blur the sensitive information. After the mosaiced video data is encoded with H264 and compressed and packaged, the desensitized video data, i.e., the target data, will be obtained.

[0071] It should be noted that there are differences in the resolution and field of view of the forward-looking, surround-looking and side-looking cameras of smart driving cars. The accuracy of a single target detection model in identifying sensitive information of all on-board cameras is limited, and there is a risk of data privacy and security. In this embodiment, different target detection models are used to desensitize sensitive information such as faces and license plates in the collected forward-looking, side-looking and surround-looking video data, respectively, which can ensure the accuracy of desensitization of each on-board camera and meet data privacy and security. In addition, when performing data desensitization, the target detection model corresponding to the camera flag is run in parallel during the idle period of the domain controller, which ensures the desensitization efficiency while saving the computing power cost of the smart driving domain controller function when it is running, achieving the effect of reducing costs and increasing efficiency, and can also ensure the safe collection of data when the resources of low-computing power platforms are limited.

[0072] In another feasible implementation, step S20 may include steps A21 to A22:

[0073] Step A21, when the vehicle is in an offline state and the data to be desensitized is detected, obtaining a delayed power-off duration;

[0074] It should be noted that the intelligent driving domain controller is equipped with a timer for controlling the delayed power-off. When it is detected that the vehicle is offline and there is data to be desensitized in the vehicle's internal storage system, the timer setting duration of the intelligent driving domain controller will be obtained, that is, the delayed power-off duration, so as to desensitize the data to be desensitized within the timer setting duration. The timer setting duration should be set according to the computing power of the intelligent driving domain controller data acquisition system to ensure that low computing power platforms can also achieve secure collection of desensitized data with limited resources.

[0075] Step A22, desensitizing the data to be desensitized within the delayed power-off time to obtain target data.

[0076] It should be understood that regardless of whether the desensitization process of all data to be desensitized is completed within the delayed power-off period, the desensitized video data will be saved as target data in the vehicle's internal storage system and the vehicle will be powered off. At the same time, the desensitization status of the target data will be marked as desensitized to avoid repeated desensitization of the data.

[0077] In a feasible implementation, step A22 may include steps B21-B22:

[0078] Step B21, when the desensitization of the data to be desensitized is completed within the delayed power-off time, the desensitized data to be desensitized is used as the target data;

[0079] It should be understood that when the amount of data in the secondary ignition cycle is small, the time required to complete desensitization will be less than the timer setting time, that is, the desensitization process of all data to be desensitized can be completed within the delayed power-off time. At this time, the intelligent driving domain controller will not control the vehicle to power off after the delayed power-off time is reached, but will immediately go into sleep mode and power off when data desensitization is completed, so as to save vehicle energy and computing resources.

[0080] Step B22, when the time for desensitizing the data to be desensitized reaches the delayed power-off time, the desensitized data to be desensitized that has been completed is used as the target data, and the undesensitized data to be desensitized is saved.

[0081] It should be understood that when the amount of data in the secondary ignition cycle is large, the time required to complete desensitization is greater than the timer setting time, that is, the desensitization process of all data to be desensitized cannot be completed within the delayed power-off time. At this time, the intelligent driving domain controller will control the vehicle to power off and enter a completely dormant state when the delayed power-off time is reached, mark the desensitization status of the target data as desensitized and save it to the vehicle's internal storage system, mark the video data that has not been desensitized as to be desensitized and save it to the vehicle's internal storage system, so that the video data that has not been desensitized can be desensitized during the next time the vehicle is locked and powered off and is not completely dormant.

[0082] Step S30, storing the target data in the internal storage system of the vehicle, and controlling the vehicle to be powered off;

[0083] It should be noted that when the target data, that is, the desensitized data, is obtained, the target data will be marked as processed and saved in the vehicle's internal storage system to avoid repeated desensitization of the target data before uploading it to the cloud. Immediately after obtaining the target data, the vehicle is powered off to put the intelligent driving domain controller into full sleep mode, which can reduce the exposure time of the data in an unprotected state and reduce the risk of data leakage or unauthorized access.

[0084] Step S40, when the vehicle is powered on again and is connected to the Internet again, the target data is uploaded to the cloud.

[0085] It should be noted that since the data desensitization process is carried out offline, the desensitized video data will not be uploaded to the cloud immediately, but will be stored in the vehicle's internal storage system. After the vehicle is powered on, the communication connection with the outside world will be re-established, and the desensitized data will be uploaded to the cloud at this time. Backing up the desensitized data will help further analysis and processing.

[0086] It should be understood that in order to ensure the stability of data upload, when it is detected that the vehicle is powered on and is connected to the Internet, the network status at this time will be detected first. When it is detected that the network status is good, the intelligent driving domain controller will initiate a communication request to the cloud, and after establishing a communication connection with the cloud, the desensitized and compressed data, that is, the target data, will be uploaded to the cloud.

[0087] The present embodiment provides a method for collecting desensitized data. When a vehicle lock command is received, the internal process of the vehicle is closed and the communication channel of the vehicle is disconnected to put the vehicle into an offline state. When the vehicle is in an offline state and the data to be desensitized is detected, the data to be desensitized is desensitized to obtain target data, the target data is saved in the internal storage system of the vehicle, and the vehicle is controlled to be powered off. When the vehicle is powered on again and the vehicle is reconnected to the network, the target data is uploaded to the cloud. The present solution collects desensitized data in an offline desensitization manner to avoid excessive consumption of computing power and load during vehicle operation, thereby reducing the risk of system stability and ensuring the stability of desensitized data collection on a low computing power platform.

[0088] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S40 also includes steps S41 to S43:

[0089] Step S41, traversing the camera flag list, and obtaining the current camera flag based on the camera flag list;

[0090] It should be noted that a camera flag list is maintained in the vehicle's internal storage system, and the camera flag list stores the camera flag corresponding to the video data recorded for each event in the current ignition cycle and the time period node corresponding to the camera flag in order of recording time.

[0091] Step S42, when the vehicle is powered on again and is in a reconnected state, obtaining current upload event data from the target data based on the current camera flag, and uploading the current upload event data to the cloud;

[0092] It should be understood that when it is detected that the vehicle is powered on and is in a stable networked state, the desensitized data will be uploaded to the cloud. In order to ensure the integrity and continuity of the data, when uploading the target data, the target data will be divided into events based on the camera flag. After the data of the same event is uploaded, the data of the next event will be uploaded. Specifically, if the current upload event is an abnormal exit of high-speed NOA, the camera flags traversed will be the front-view flag and the side-rear flag. The time period information corresponding to the front-view flag and the side-rear flag can be obtained based on the camera flag list. At this time, the video data that is first desensitized based on the front-view flag and the side-rear flag will be read from the target data based on the time period information, as the current upload event data, and the current upload event data will be uploaded to the cloud, and the uploaded target data status will be marked as uploaded.

[0093] Step S43, when the upload of the current upload event data is completed, the next camera flag is obtained based on the camera flag list, the next upload event data is obtained from the target data based on the next camera flag, and the next upload event data is uploaded to the cloud until the upload of the target data is completed.

[0094] It should be understood that when the current upload event data read from the target data based on the current camera flag has been uploaded, the next camera flag will be obtained based on the camera flag list, and the time period information corresponding to the next camera flag will be obtained. The first video data to be desensitized based on the next camera flag will be read from the target data that has not been uploaded, as the next upload event data, and the next upload event data will be uploaded to the cloud, and the status of the uploaded target data will be marked as uploaded. Until the status of all target data is marked as uploaded, the original data (i.e., the data to be desensitized) and the desensitized and compressed data (i.e., the target data) are cleared to release space for new data recording.

[0095] This embodiment divides the desensitized data into different events based on the camera flag bit. After uploading the data of the same event, the data of the next event is uploaded, thereby ensuring the integrity and continuity of the data during the uploading process.

[0096] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the desensitized data collection method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
