It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, a schematic diagram of an implementation environment provided by an embodiment of the application is shown. The implementation environment includes a vehicle 100. Vehicle 100 refers to a powered or towed Vehicle for use by a person or for transporting goods, and includes, but is not limited to, a car, a Sport Utility Vehicle (SUV), a Multi-Purpose Vehicle (MPV), and the like. The vehicle 100 is provided with an image acquisition device and an electronic controller, which are communicatively connected to each other.
The image acquisition device is used for recording environmental information during the driving process of the vehicle 100. Optionally, the image capturing device is a vehicle data recorder, and the vehicle data recorder can be installed on the front windshield of the vehicle close to the rear of the central rearview mirror. In some embodiments, the vehicle event data recorder continues to perform image acquisition during the driving process of the vehicle 100 to obtain a plurality of videos with the same duration, and then sequentially sends the videos to the electronic controller, and the electronic controller stores the videos, but deletes the videos when the storage duration of the videos reaches a preset duration so as to accommodate videos newly acquired by the vehicle event data recorder. This mode of operation is referred to as a loop recording mode.
The electronic controller is used to process various services in the vehicle 100, including, but not limited to: control of drive systems, control of brake systems, control of entertainment systems, control of environmental components within the vehicle, such as air conditioners, mood lights, etc. In the embodiment of the application, when the electronic controller monitors that the vehicle enters an emergency state (for example, a collision accident occurs, an emergency brake occurs, and the like), the electronic controller multiplexes videos acquired by the image acquisition device in a cyclic recording mode, and splices the videos to obtain an emergency state video for recording environmental information of the vehicle 100 before and after the vehicle enters the emergency state, and the process only consumes a small amount of computing power of the electronic controller, so that the consumption of hardware resources of the electronic controller is reduced, and therefore the electronic controller has enough hardware resources to process other services in the vehicle 100, and the pause feeling is reduced.
Referring to fig. 2, a flowchart of a video processing method according to an embodiment of the present application is shown. The execution subject of each step in the method may be an electronic controller, and the method includes the following processes.
Step S201, continuously collecting N videos through an image collecting device, and storing the N videos in a first appointed folder.
N is a positive integer greater than 2. In the examples of the present application. The image acquisition device continuously acquires videos in the driving process of the vehicle to obtain N videos with the same duration.
And deleting the videos in the first appointed folder when the storage time is longer than or equal to the preset time so as to accommodate the videos newly acquired by the image acquisition device. In other possible embodiments, in the event that the data amount of the video in the first designated folder is greater than the preset data amount, the electronic controller deletes the first stored video or videos to accommodate the video newly captured by the image capture device.
Step S202, after the vehicle is monitored to be in the emergency state, the target video is obtained from the N videos based on the time information of the vehicle entering the emergency state.
Emergency conditions include, but are not limited to: the emergency state represents that the vehicle is likely to have an accident, and at the moment, the current environmental information of the vehicle needs to be accurately recorded so as to facilitate the follow-up rescue, pursuit and the like.
In some embodiments, the vehicle obtains the vehicle acceleration in real time through the acceleration sensor, and determines that the vehicle enters the emergency state in the case that the absolute value of the vehicle acceleration is greater than a first preset value. The first predetermined value is set experimentally or empirically, and is not limited in the embodiments of the present application. The absolute value of the acceleration of the vehicle is larger than a first preset value, and the vehicle is represented to have sudden braking or suddenly accelerate. It should be noted that, when the vehicle just enters the driving state, there is also a case of a large acceleration, however, this is not a case that the vehicle has an accident, and therefore, when it is determined whether the vehicle enters the emergency state through the acceleration of the vehicle, 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 is indicated that the vehicle is in the starting acceleration stage with a high probability, but not in the emergency state, and 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 is indicated that the vehicle enters the emergency state.
In other embodiments, the vehicle monitors a change in steering wheel angle and determines that the vehicle is in an emergency state if the rate of change of steering wheel angle is greater than a second predetermined value. The second predetermined value is set experimentally or empirically, and is not limited in the embodiments of the present application. The change rate of the steering wheel angle is larger than a second preset value, which represents that the steering wheel angle of the vehicle is changed greatly in a short time, namely that the vehicle is turned emergently.
In other embodiments, the vehicle determines that it is in an emergency state in the event that a collision event is detected. Optionally, the vehicle may analyze the video frames captured by the image capture device to determine whether a collision event has occurred.
In some embodiments, the time information that the vehicle enters the emergency state includes a target time at which the vehicle enters the emergency state, and the target videos include a first target video, a second target video, and a third target video. In this embodiment, step S202 may alternatively be implemented as the following sub-steps: after the vehicle is monitored to be in an emergency state, determining a video with the acquisition time including a target moment in the N videos as a first target video; determining videos, of which the acquisition time is before the acquisition time of the first target video and the time interval between the acquisition time of the first target video and the acquisition time of the N videos is smaller than or equal to the first time interval, as second target videos; and determining the video, of the N videos, of which the acquisition time is after the acquisition time of the first target video and the time interval with the acquisition time of the first target video is less than or equal to the second time interval as a 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 collecting device, and the first time interval and the second time interval can be the same or different. Specifically, the first time interval may be a positive integer multiple of a duration of a video acquired by the image acquisition device, and the second time interval may also be a positive integer multiple of a duration of a video acquired by the image acquisition device, so that when an emergency video is generated subsequently, the video acquired by the image acquisition video may be directly acquired without splitting the video.
Further, the above-mentioned first time interval and second time interval are the duration of the image capturing video, and further, determining, as the second target video, a video of which the capturing time is before the capturing time of the first target video and the time interval with the capturing time of the first target video is less than or equal to the first time interval, the video of which the capturing time is before the capturing time of the first target video among the N videos, includes: and determining the video with the acquisition time before that of the first target video and the minimum time interval with the acquisition time of the first target video in the N videos as a second target video. Determining a video, of the N videos, of which the acquisition time is after the acquisition time of the first target video and the time interval with the acquisition time of the first target video is less than or equal to the second time interval, as a third target video, including: and determining the video with the acquisition time after the acquisition time of the first target video and the minimum time interval with the acquisition time of the first target video in the N videos as a third target video.
Referring collectively to fig. 3, a schematic diagram of video processing provided by one embodiment of the present application is shown. The image acquisition device acquires N videos in a circulating recording mode, at the time of t0, the vehicle monitors that the vehicle enters an emergency state, then searches videos with acquisition time including the time of t0 from the N videos to serve as a first target video 31, then determines a video with the acquisition time being before the acquisition time of the first target video 31 and closest to the acquisition time of the first target video 31 to be a second target video 32, and determines a video with the acquisition time being after the acquisition time of the first target video 31 and closest to the acquisition time of the first target video 31 to be a third target video 33.
It should be noted that the acquisition time of the first target video, the acquisition time of the second target video, and the acquisition time of the third target video may be the same or different. In some embodiments, the vehicle acquires the second target video when entering the emergency state, the first target video when the first target video acquisition is completed, and the third target video when the third target video acquisition is completed. In other embodiments, the vehicle simultaneously acquires the first target video, the second target video, and the third target video after the third target video is captured.
In other possible embodiments, if the image capture device is not capturing video before the emergency state (e.g., the image capture device is in a state of being just installed), the electronic controller may obtain a first target video whose capture time includes the target time, and a third target video whose capture time is after the target time; if the image acquisition device stops working after the vehicle enters an emergency state, the electronic controller can acquire a first target video with acquisition time including a target moment and a third target video with acquisition time 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.
And step S203, under the condition that a plurality of target videos exist, splicing the plurality of target videos to obtain an emergency state video, and storing the emergency state video in a second specified folder.
The emergency video is used for recording environmental information of the vehicle before and after entering the emergency state. The video in the second designated folder does not respond to the designated deletion instruction, and the designated deletion instruction is a deletion instruction other than the deletion instruction triggered by the user, that is, the file in the designated storage path can only be deleted manually by the user and cannot be deleted automatically, so that the situation that the emergency video is deleted by mistake is avoided, and the situation that the emergency video is deleted by mistake is avoided. The first designated folder and the second designated folder are not identical.
In the case where the target video includes the first target video, the second target video, and the third target video, step S203 is implemented as: and splicing the second target video, the first target video and the third target video end to end according to the sequence of the acquisition time to obtain the emergency state video.
Under the condition that the target video comprises the first target video and the third target video, the step S203 is implemented by splicing the first target video and the third target video end to end according to the sequence of the acquisition time to obtain the emergency state video. Under the condition that the target video comprises the first target video and the second target video, the step S203 is implemented by splicing the second target video and the first target video end to end according to the sequence of the acquisition time to obtain the emergency state video. In the event that the target video includes only the first target video, the electronic controller determines the first target video as an emergency status video. Referring to fig. 3 again, the electronic controller sequentially stitches the second target video 32, the first target video 31, and the third target video 33 to obtain an emergency state video 34.
To sum up, the technical scheme provided by the embodiment of the application obtains three target videos from a plurality of videos acquired by the image acquisition device in a circulating recording mode after the vehicle enters the emergency state, so as to splice and obtain the emergency state videos for recording environmental information before and after the vehicle enters the emergency state, and the videos acquired by the image acquisition device in the circulating recording mode are multiplexed in the process of obtaining the emergency state videos, so that the video splicing process only consumes a small amount of calculation power of the electronic controller, the consumption of hardware resources of the electronic controller is reduced, and therefore the electronic controller has enough hardware resources to process other services in the vehicle, and the pause feeling of the vehicle is reduced.
In some embodiments, after the vehicle obtains the emergency video, the name of the emergency video may also be set for subsequent searching. Optionally, the vehicle sets the name of the emergency state video based on the time information that the vehicle enters the emergency state. Optionally, the name of the emergency video contains the time information. For example, if the target time of the vehicle entering the emergency state is 10/19/2022 at 15 pm for 23 minutes, the name of the emergency state video may be "2210191523". By the method, the user can quickly search the emergency state video according to the time when the vehicle enters the emergency state, and the searching efficiency is improved.
Further, the vehicle may 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 where the vehicle is located when the vehicle enters the emergency state. The vehicle can acquire the position information of the vehicle when the vehicle enters the emergency state through the positioning module. The positioning module may be a GPS module in a vehicle. In this embodiment, the name of the emergency state video includes, in addition to the above time information, position information where the vehicle is located when entering the emergency state. In conjunction with the above example, the vehicle may have a rear-end collision at the xx high-speed toll station at 15 pm, 23 pm, 10/19/2022, and the name of the emergency video may be set to "xx high-speed toll station 2210191523". By the method, the user can quickly search the video in the emergency state according to the time and the position information of the vehicle entering the emergency state, and the searching efficiency is improved.
In some embodiments, the vehicle may also obtain a target video frame from the emergency video and then set the target video frame as a video cover of the emergency video. The target video frame is used for recording environmental information when the vehicle enters an emergency state, namely the target video frame is a video frame collected by the image collecting device when the vehicle enters the emergency state (namely the target moment). By the method, the user can quickly know the content of the emergency video when looking at the video interface of the emergency video.
Referring to fig. 4, a flowchart of a video processing method according to an embodiment of the present application is shown. The method comprises the following processes.
Step S401, continuously collecting N videos through an image collecting device, and storing the N videos in a first appointed folder.
And deleting the videos in the first appointed folder under the condition that the storage time length is greater than or equal to the preset time length.

Step S403, when there are multiple target videos, performing stitching processing on the multiple target videos to obtain an emergency video, and storing the emergency video in a second designated folder.
The emergency video is used for recording 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 instruction, and the designated deletion instruction is a deletion instruction other than the deletion instruction triggered by the user.
Step S404, after receiving a playing instruction for the emergency video, playing the emergency video.
In some embodiments, the vehicle is provided with a touch-controlled center control screen, the name of the emergency state video is displayed on the center control screen, and the electronic controller receives the playing instruction when the triggering signal for the name of the emergency state video is acquired. The trigger signal may 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 center control screen and an operable control, and a user can trigger the play instruction for the emergency state video through the triggering operation of the operable control. In other embodiments, the playing instruction is a voice signal, the electronic controller collects the voice signal through the voice collecting device, and receives the playing instruction when the voice signal is detected to include the specified keyword.
Step S405, in the process of playing the emergency video, displaying a playing progress bar of the emergency video.
The playing progress bar is used for indicating the playing progress of the emergency video. The play progress bar includes a target mark. The target mark is used for marking a video frame collected by the image collecting device when the vehicle enters an emergency state.
Referring to fig. 5 in combination, which shows a schematic view of playing an emergency video provided in an embodiment of the present application, in the process of playing the emergency video, the central control screen displays a play progress bar 51, and the play progress bar 51 includes a target mark 52.
And step S406, after receiving the trigger signal aiming at the target mark, displaying the video frame collected by the image collecting 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 of the user for the target mark. Furthermore, the trigger signal may also be a speech signal.
In the embodiment of the application, after the user triggers the target mark through the trigger signal, the central control screen skips to display the video frame acquired by the image acquisition device when the vehicle enters the emergency state, and through the mode, the picture when the vehicle enters the emergency state can be quickly positioned, so that the searching efficiency is improved. Referring again to fig. 5, after the user triggers the target mark 52, the central control screen displays a video frame 53 captured by the image capturing device when the vehicle enters an emergency state.
To sum up, according to the technical scheme provided by the embodiment of the application, the target mark is displayed on the playing progress bar of the emergency state video when the emergency state video is played, and after the target mark is triggered by a user, the central control screen skips to display the video frame acquired by the image acquisition device when the vehicle enters the emergency state, so that the rapid positioning of the image when the vehicle enters the emergency state is realized, and the searching efficiency is improved.
In some embodiments, the vehicle further performs subsequent video processing steps to obtain the emergency state video if it is monitored that the ratio between the available hardware resources of the electronic controller and the total hardware resources is less than a preset ratio. The preset proportion is set according to experiments or experience. The occupation ratio between the available hardware resources of the electronic controller and the total hardware resources is smaller than the preset occupation ratio, so that the available hardware resources of the electronic controller are insufficient, the video acquired by the image acquisition device in a circulating recording mode can be multiplexed at the moment, the calculation power is reduced, the consumption of the hardware resources of the electronic controller is reduced, the electronic controller has enough hardware resources to process other services, and the stuck feeling is reduced.
