Detailed ways

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

Please refer to FIG1 , which shows a schematic diagram of an implementation environment provided by an embodiment of the present application. The implementation environment includes a vehicle 100. The vehicle 100 refers to a vehicle driven or towed by a power device for passengers or for transporting goods, including but not limited to a sedan, a suburban utility vehicle (SUV), a multi-purpose vehicle (MPV), etc. The vehicle 100 is provided with an image acquisition device and an electronic controller, and a communication connection is established between the image acquisition device and the electronic controller.

The image acquisition device is used to record environmental information during the driving process of the vehicle 100. Optionally, the image acquisition device is a driving recorder, which can be installed at a position behind the upper central rearview mirror of the front windshield of the car. In some embodiments, the driving recorder continuously acquires images during the driving process of the vehicle 100 to obtain several videos of the same duration, and then sends the above videos to the electronic controller in sequence. The electronic controller stores the above videos, but when the storage duration of the above videos reaches a preset duration, it is deleted to accommodate the newly collected video of the driving recorder. The above working mode is called a loop recording mode.

The electronic controller is used to process various services in the vehicle 100, including but not limited to: control of the drive system, control of the brake system, control of the entertainment system, and control of the in-vehicle environmental components (such as air conditioning, ambient lighting, etc.). In the embodiment of the present application, when the electronic controller detects that an emergency state has been entered (such as a collision accident, sudden braking, etc.), it reuses the video collected by the image acquisition device through a loop recording method, and splices the above multiple videos to obtain an emergency state video for recording the environmental information of the vehicle 100 before and after entering the emergency state. This process consumes only a small amount of computing power of the electronic controller, reducing the consumption of the hardware resources of the electronic controller, so that the electronic controller has sufficient hardware resources to process other services in the vehicle 100 and reduce the sense of jamming.

Please refer to Figure 2, which shows a flow chart of a video processing method provided by an embodiment of the present application. The execution subject of each step in the method can be an electronic controller, and the method includes the following process.

Step S201: continuously capture N videos through an image capture device, and store the N videos in a first designated folder.

N is a positive integer greater than 2. In the embodiment of the present application, the image acquisition device continuously acquires videos during the driving of the vehicle to obtain N videos of the same length.

The videos in the first designated folder are deleted when the storage time is greater than or equal to the preset time to accommodate the videos newly collected by the image acquisition device. In other possible implementations, when the data volume of the videos in the first designated folder is greater than the preset data volume, the electronic controller deletes one or more videos stored first to accommodate the videos newly collected by the image acquisition device.

Step S202, after monitoring that the vehicle is in an emergency state, a target video is obtained from N videos based on the time information when the vehicle enters the emergency state.

Emergency states include but are not limited to: sudden braking of the vehicle, sudden acceleration of the vehicle, collision of the vehicle, large changes in the steering wheel angle of the vehicle, etc. The above emergency states indicate that the vehicle is likely to have an accident. At this time, it is necessary to accurately record the current environmental information of the vehicle for subsequent rescue, accountability, etc.

In some embodiments, the vehicle obtains the vehicle acceleration in real time through the acceleration sensor, and when the absolute value of the vehicle acceleration is greater than the first preset value, it is determined that the vehicle enters an emergency state. The first preset value is set according to experiments or experience, and the embodiments of the present application are not limited to this. The absolute value of the vehicle acceleration is greater than the first preset value, indicating that the vehicle brakes suddenly, or the vehicle accelerates suddenly. It should be noted that when the vehicle just enters the driving state, there is also a situation where the acceleration is large, but this is not an accident of the vehicle. Therefore, when judging whether the vehicle enters an emergency state by the vehicle acceleration, it is also necessary to obtain the driving speed of the vehicle before the acceleration is greater than the first preset value. If the driving speed of the vehicle before the acceleration is greater than the first preset value is less than the preset driving speed, it indicates that the vehicle is most likely in the starting acceleration stage, rather than entering an emergency state. If the driving speed of the vehicle before the acceleration is greater than the first preset value is greater than the preset driving speed, it indicates that the vehicle enters an emergency state.

In other embodiments, the vehicle monitors the change of the steering wheel angle, and when the change rate of the steering wheel angle is greater than a second preset value, it is determined that the vehicle has entered an emergency state. The second preset value is set based on experiments or experience, and the embodiments of the present application are not limited to this. The change rate of the steering wheel angle is greater than the second preset value, indicating that the steering wheel angle of the vehicle has changed significantly in a short period of time, that is, the vehicle has made an emergency turn.

In other embodiments, the vehicle determines that it is in an emergency state when a collision event is detected. Optionally, the vehicle can analyze the video frames captured by the image acquisition device to determine whether a collision event has occurred.

In some embodiments, the time information of the vehicle entering the emergency state includes the target moment when the vehicle enters the emergency state, and the target video includes a first target video, a second target video, and a third target video. In this embodiment, step S202 can be replaced by the following sub-steps: after monitoring that the vehicle is in an emergency state, the video whose acquisition time includes the target moment among the N videos is determined as the first target video; the video whose acquisition time among the N videos is before the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is less than or equal to the first time interval is determined as the second target video; the video whose acquisition time among the N videos is after the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is less than or equal to the second time interval is determined as the third target video.

The first time interval and the second time interval can be determined according to the duration of the video collected by the image acquisition device, and the two can be the same or different. Specifically, the first time interval can be a positive integer multiple of the duration of the video collected by the image acquisition device, and the second time interval can also be a positive integer multiple of the duration of the video collected by the image acquisition device, so that when the emergency state video is subsequently generated, the video collected by the image acquisition video can be directly obtained without splitting it.

Furthermore, the first time interval and the second time interval are both the duration of the image acquisition video. Furthermore, the video whose acquisition time among the N videos is before the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is less than or equal to the first time interval is determined as the second target video, including: the video whose acquisition time among the N videos is before the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is the smallest is determined as the second target video. The video whose acquisition time among the N videos is after the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is less than or equal to the second time interval is determined as the third target video, including: the video whose acquisition time among the N videos is after the acquisition time of the first target video and whose time interval with the acquisition time of the first target video is the smallest is determined as the third target video.

Combined with reference to Figure 3, it shows a schematic diagram of video processing provided by an embodiment of the present application. The image acquisition device acquires N videos in a loop recording manner. At time t0, the vehicle detects that it has entered an emergency state, and then searches for a video whose acquisition time includes time t0 in the above N videos as the first target video 31, and then determines the video whose acquisition time is before the acquisition time of the first target video 31 and closest to the acquisition time of the first target video 31 as the second target video 32, and determines the video whose acquisition time is after the acquisition time of the first target video 31 and closest to the acquisition time of the first target video 31 as the third target video 33.

It should be noted that the acquisition time of the first target video, the second target video, and the third target video may be the same or different. In some embodiments, the vehicle acquires the second target video when entering an emergency state, acquires the first target video when the acquisition of the first target video is completed, and acquires the third target video when the acquisition of the third target video is completed. In other embodiments, the vehicle acquires the first target video, the second target video, and the third target video at the same time after the acquisition of the third target video is completed.

In other possible implementations, if the image acquisition device does not perform video acquisition before entering an emergency state (for example, the image acquisition device is in a newly installed state), the electronic controller may acquire a first target video whose acquisition time includes the target moment, and a third target video whose acquisition time is after the target moment; if the image acquisition device stops working after the vehicle enters an emergency state, the electronic controller may acquire a first target video whose acquisition time includes the target moment, and a third target video whose acquisition time is before the target moment; if both of the above situations occur, the electronic controller may only acquire the first target video whose acquisition time includes the target video.

Step S203: when there are multiple target videos, the multiple target videos are spliced together to obtain an emergency state video, and the emergency state video is stored in a second designated folder.

Emergency videos are used to record the environment information before and after the vehicle enters an emergency state. The videos in the second designated folder do not respond to designated deletion instructions. Designated deletion instructions are deletion instructions other than deletion instructions triggered by the user. That is, the files in the designated storage path can only be deleted manually by the user and will not be automatically deleted, so as to avoid accidental deletion of emergency videos. The first designated folder and the second designated folder are different.

When the target video includes the first target video, the second target video and the third target video, step S203 is implemented as follows: splicing the second target video, the first target video and the third target video in the order of acquisition time to obtain the emergency state video.

In the case where the target video includes the first target video and the third target video, step S203 is implemented by splicing the first target video and the third target video end to end in the order of acquisition time to obtain an emergency state video. In the case where the target video includes the first target video and the second target video, step S203 is implemented by splicing the second target video and the first target video end to end in the order of acquisition time to obtain an emergency state video. In the case where the target video only includes the first target video, the electronic controller determines the first target video as the emergency state video. Please refer to Figure 3 again. The electronic controller splices the above-mentioned second target video 32, the first target video 31, and the third target video 33 in sequence to obtain an emergency state video 34.

To summarize, the technical solution provided by the embodiment of the present application obtains three target videos from multiple videos captured by an image acquisition device in a loop recording manner after the vehicle enters an emergency state, so as to splice them together to obtain an emergency state video for recording environmental information before and after the vehicle enters the emergency state. Since the videos captured by the image acquisition device in a loop recording manner are reused in the process of obtaining the emergency state video, the video splicing process only consumes a small amount of computing power of the electronic controller, thereby reducing the consumption of the hardware resources of the electronic controller, so that the electronic controller has sufficient hardware resources to handle other services in the vehicle and reduce the sense of lag.

In some embodiments, after the vehicle obtains the emergency state video, the name of the emergency state video can also be set for subsequent search. Optionally, the vehicle sets the name of the emergency state video based on the time information when the vehicle enters the emergency state. Optionally, the name of the emergency state video contains the above time information. For example, if the target time for the vehicle to enter the emergency state is 15:23 pm on October 19, 2022, the name of the emergency state video can be "2210191523". In the above manner, users can quickly find emergency state videos according to the time when the vehicle enters the emergency state, thereby improving search efficiency.

Furthermore, the vehicle can also set the name of the emergency state video based on the time information when the vehicle enters the emergency state and the location information when the vehicle enters the emergency state. Among them, the vehicle can obtain the location information of the vehicle when it enters the emergency state through the positioning module. The above positioning module can be a GPS module in the vehicle. In this embodiment, in addition to the above time information, the name of the emergency state video also includes the location information of the vehicle when it enters the emergency state. Combined with the above example, the vehicle had a rear-end collision at the xx highway toll station at 15:23 pm on October 19, 2022. At this time, the name of the emergency state video can be set to "xx Highway Toll Station 2210191523". In the above way, users can quickly find emergency state videos according to the time and location information when the vehicle enters the emergency state, thereby improving search efficiency.

In some embodiments, the vehicle can also obtain a target video frame from the emergency video, and then set the target video frame as the video cover of the emergency video. The target video frame is used to record the environmental information when the vehicle enters the emergency state, that is, the target video frame is the video frame captured by the image acquisition device when the vehicle enters the emergency state (that is, the target moment). In the above manner, when the user views the video cover of the emergency video, he can quickly understand the content of the emergency video.

Please refer to Figure 4, which shows a flow chart of a video processing method provided by an embodiment of the present application. The method includes the following process.

Step S401: continuously capture N videos through an image capture device, and store the N videos in a first designated folder.

The videos in the first designated folder are deleted when the storage duration is greater than or equal to the preset duration.

Step S402, after monitoring that the vehicle is in an emergency state, a target video is obtained from N videos based on the time information when the vehicle enters the emergency state.

Step S403: when there are multiple target videos, the multiple target videos are spliced to obtain an emergency state video, and the emergency state video is stored in a second designated folder.

The emergency state video is used to record the environmental information of the vehicle before and after entering the emergency state. The files in the second designated folder do not respond to the designated deletion command, and the designated deletion command is a deletion command other than the deletion command triggered by the user.

Step S404, after receiving the play instruction for the emergency state video, play the emergency state video.

In some embodiments, the vehicle is provided with a touch-sensitive central control screen, and the central control screen displays the name of the emergency video. When a trigger signal for the name of the emergency video is obtained, the electronic controller receives the above-mentioned play instruction. The above-mentioned trigger signal can be any one of a single-click trigger signal, a double-click trigger signal, and a long-press trigger signal. In some embodiments, the vehicle is provided with a non-touch-sensitive central control screen and operable controls. The user can trigger the operable controls to trigger the play instruction for the emergency video. In other embodiments, the play instruction is a voice signal, and the electronic controller collects the voice signal through a sound collection device. When it is detected that the sound signal includes a specified keyword, the play instruction is received.

Step S405: During the process of playing the emergency video, a playing progress bar of the emergency video is displayed.

The play progress bar is used to indicate the play progress of the emergency state video. The play progress bar includes a target mark. The target mark is used to mark the video frame collected by the image acquisition device when the vehicle enters the emergency state.

With reference to FIG5 , which shows a schematic diagram of playing an emergency status video provided in one embodiment of the present application, the central control screen displays a playing progress bar 51 during playing the emergency status video, and the playing progress bar 51 includes a target mark 52 .

Step S406, after receiving the trigger signal for the target mark, display the video frame captured by the image acquisition device when the vehicle enters the emergency state.

The trigger signal may be any one of a single-click trigger signal, a double-click trigger signal, and a long-press trigger signal for the target mark by the user. In the embodiment of the present application, only a single-click trigger signal is used as an example for explanation. In addition, the trigger signal may also be a voice signal.

In the embodiment of the present application, after the user triggers the target mark through the trigger signal, the central control screen jumps to display the video frame collected by the image acquisition device when the vehicle enters the emergency state. In this way, the image when the vehicle enters the emergency state can be quickly located to improve the search efficiency. Please refer to Figure 5 again. After the user triggers the target mark 52, the central control screen displays the video frame 53 collected by the image acquisition device when the vehicle enters the emergency state.

To sum up, the technical solution provided in the embodiment of the present application also displays a target mark on the playback progress bar of the emergency state video when playing the emergency state video. When the user triggers the target mark, the central control screen will jump to display the video frame captured by the image acquisition device when the vehicle enters the emergency state, thereby realizing rapid positioning of the picture when the vehicle enters the emergency state and improving search efficiency.

In some embodiments, when the vehicle also detects that the ratio between the available hardware resources of the electronic controller and the total hardware resources is less than a preset ratio, subsequent video processing steps are performed to obtain emergency status videos. The preset ratio is set based on experiments or experience. If the ratio between the available hardware resources of the electronic controller and the total hardware resources is less than the preset ratio, it means that the available hardware resources of the electronic controller are insufficient. At this time, the video collected by the image acquisition device through loop recording can be reused to reduce computing power and reduce the consumption of hardware resources of the electronic controller, so that the electronic controller has sufficient hardware resources to handle other services and reduce the sense of jamming.

Please refer to FIG6 , which shows a structural block diagram of a video processing device provided by an embodiment of the present application. The device includes: a video acquisition module 610 , a first storage module 620 , a video acquisition module 630 , a video processing module 630 and a second storage module 650 .

The video acquisition module 610 is used to continuously acquire N videos through an image acquisition device, where N is a positive integer greater than 2.

The first storage module 620 is used to store N videos in a first designated folder. The videos in the first designated folder are deleted when the storage time is greater than or equal to a preset time.

The video acquisition module 630 is used to acquire a target video from multiple videos based on the time information when the vehicle enters the emergency state after monitoring that the vehicle is in the emergency state.

The video processing module 640 is used to splice the target videos to obtain an emergency state video when there are multiple target videos. The emergency state video is used to record the environmental information of the vehicle before and after entering the emergency state.

The second storage module 650 is used to store the emergency status video in a second designated folder, wherein the files in the second designated folder do not respond to a designated deletion instruction, and the designated deletion instruction is a deletion instruction other than a deletion instruction triggered by a user.

To summarize, the technical solution provided by the embodiment of the present application obtains three target videos from multiple videos captured by an image acquisition device in a loop recording manner after the vehicle enters an emergency state, so as to splice them together to obtain an emergency state video for recording environmental information before and after the vehicle enters the emergency state. Since the videos captured by the image acquisition device in a loop recording manner are reused in the process of obtaining the emergency state video, the video splicing process only consumes a small amount of computing power of the electronic controller, thereby reducing the consumption of the hardware resources of the electronic controller, so that the electronic controller has sufficient hardware resources to handle other services in the vehicle and reduce the sense of lag.
