Referring to fig. 1, a schematic diagram of an implementation environment provided by an embodiment of the present application is shown. The implementation environment includes a vehicle 100. Vehicle 100 refers to a Vehicle that is powered or towed by a power plant, for passengers or for transporting items, including, but not limited to, a car, a sport utility Vehicle (Suburban Utility Vehicle, SUV), a utility Vehicle (MPV), and the like. The vehicle 100 is provided with an image pickup device and an electronic controller, between which a communication connection is established.
The image acquisition device is used for recording environmental information during the running of the vehicle 100. Optionally, the image acquisition device is a vehicle recorder, and the vehicle recorder can be installed at a position of the front windshield of the vehicle, which is close to the rear of the central rearview mirror. In some embodiments, the vehicle recorder continuously performs image acquisition during the running 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 to accommodate the newly acquired videos of the vehicle recorder when the storage duration of the videos reaches the preset duration. This mode of operation is referred to as a cyclic 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, control of in-vehicle environmental components (such as air conditioning, atmosphere lights, etc.). In the embodiment of the application, when the electronic controller monitors that the vehicle enters an emergency state (such as a collision accident, emergency brake, etc.), the image acquisition device multiplexes the videos acquired by the image acquisition device in a cyclic recording mode, and splices the videos to obtain an emergency state video for recording the environmental information of the vehicle 100 before and after entering the emergency state, the process only consumes a small amount of calculation force of the electronic controller, reduces the consumption of hardware resources of the electronic controller, and further enables the electronic controller to have enough hardware resources to process other services in the vehicle 100, and reduces the jamming feeling.
Referring to fig. 2, a flowchart of a video processing method according to an embodiment of the application is shown. The main execution body of each step in the method can be an electronic controller, and the method comprises the following processes.
Step S201, N videos are continuously collected by the image collecting device, and the N videos are stored in the first designated folder.
N is a positive integer greater than 2. In the embodiment of the application. The image acquisition device is used for continuously acquiring videos in the running process of the vehicle to obtain N videos with the same duration.
And deleting the video in the first designated folder under the condition that the storage time length is greater than or equal to the preset time length so as to accommodate the video newly acquired by the image acquisition device. In other possible embodiments, in the case where the data amount of the video in the first designated folder is greater than the preset data amount, the electronic controller deletes the one or more videos stored first to accommodate the video newly acquired by the image acquisition device.
Step S202, after the vehicle is monitored to be in an emergency state, acquiring target videos from N videos based on time information of the vehicle entering the emergency state.
Emergency conditions include, but are not limited to: the emergency state represents that the vehicle has a high probability of accident, and the current environmental information of the vehicle needs to be accurately recorded at the moment so as to facilitate subsequent rescue, responsibility following and the like.
In some embodiments, the vehicle acquires the vehicle acceleration in real time through the acceleration sensor, and determines that the vehicle enters an emergency state when the absolute value of the vehicle acceleration is greater than a first preset value. The first preset value is set according to experiments or experience, which is not limited in the embodiment of the present application. The absolute value of the vehicle acceleration is greater than a first preset value, which indicates that the vehicle is suddenly braked or suddenly accelerated. It should be noted that, even when the vehicle is in the running state, there is a case where the acceleration is large, however, this is not an accident of the vehicle, so when judging whether the vehicle is in the emergency state by the acceleration of the vehicle, it is also necessary to acquire the running speed of the vehicle before the acceleration is larger than the first preset value, if the running speed of the vehicle before the acceleration is larger than the first preset value is smaller than the preset running speed, it is indicated that the vehicle is in the starting acceleration stage with a large probability, but not in the emergency state, and if the running speed of the vehicle before the acceleration is larger than the first preset value is larger than the preset running speed, it is indicated that the vehicle is in the emergency state.
In other embodiments, the vehicle monitors a change in steering wheel angle and determines that the vehicle is in an emergency condition if the rate of change of steering wheel angle is greater than a second predetermined value. The second preset value is set according to experiments or experience, which is not limited in the embodiment of the present application. The change rate of the steering wheel angle is larger than a second preset value, and the steering wheel angle of the vehicle is represented to be changed greatly in a short time, namely, the vehicle turns emergently.
In other embodiments, the vehicle is determined to be in an emergency condition in the event of a detected collision event. Alternatively, the vehicle may analyze the video frames acquired by the image acquisition device to determine whether a collision event has occurred.
In some embodiments, the time information for the vehicle to enter the emergency state includes a target time at which 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 may alternatively be implemented as the following sub-steps: after the fact that the vehicle is in an emergency state is monitored, determining a video with the acquisition time including a target moment in N videos as a first target video; determining a video with the acquisition time of N videos being before the acquisition time of the first target video and the time interval between the N videos and the acquisition time of the first target video being smaller than or equal to the first time interval as a second target video; and determining the video with the acquisition time of the first target video after the acquisition time of the N videos and the time interval between the N videos and the acquisition time of the first target video being smaller 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 acquired by the image acquisition 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 the video acquired by the image acquisition device, and the second time interval may also be a positive integer multiple of a duration of the video acquired by the image acquisition device, so that the video acquired by the image acquisition video can be directly acquired without splitting the video when the emergency video is generated subsequently.
Further, the first time interval and the second time interval are both durations of image acquisition videos, and further, determining, as the second target video, a video having a time interval smaller than or equal to the first time interval between the acquisition time of the first target video and a time interval between the acquisition time of the first target video and the acquisition time of the N videos before the acquisition time of the first target video, includes: and determining the video with the smallest time interval between the acquisition time of the first target video and the acquisition time of the first target video in the N videos as the second target video. Determining, as a third target video, a video having a collection time of N videos after a collection time of the first target video and a time interval between the collection time of the N videos and the collection time of the first target video being less than or equal to the second time interval, including: and determining the video with the smallest time interval between the acquisition time of the first target video and the acquisition time of the first target video after the acquisition time of the first target video in the N videos as a third target video.
Referring in conjunction 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 cyclic recording mode, at the time t0, the vehicle monitors that the vehicle enters an emergency state, then searches videos with the acquisition time including the time t0 from the N videos to serve as first target videos 31, then determines the video with the acquisition time before the acquisition time of the first target videos 31 and closest to the acquisition time of the first target videos 31 as second target videos 32, and determines the video with the acquisition time after the acquisition time of the first target videos 31 and closest to the acquisition time of the first target videos 31 as third target videos 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 upon entering the emergency state, acquires the first target video upon completion of the first target video acquisition, and acquires the third target video upon completion of the third target video acquisition. In other embodiments, the vehicle acquires the first target video, the second target video, and the third target video simultaneously after the third target video acquisition is completed.
In other possible embodiments, if the image capturing device does not capture video before being in an emergency state (for example, the image capturing device is in a state of being just installed), the electronic controller may acquire a first target video whose capturing time includes a target time, and a third target video whose capturing 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 target time and a third target video with acquisition time before the target time; if both of the above situations occur, the electronic controller may acquire only the first target video whose acquisition time includes the target video.
In step S203, if there are multiple target videos, the multiple target videos are spliced to obtain an emergency video, and the emergency video is stored in a second designated folder.
The emergency video is used for recording the environment information of the vehicle before and after entering the emergency. The video in the second designated folder does not respond to the designated deleting instruction, and the designated deleting instruction is other deleting instructions except the deleting instruction triggered by the user, namely, the files in the designated storage path can only be manually deleted by the user and cannot be automatically deleted, so that the situation that the video in the emergency state is deleted by mistake is avoided, and the situation that the video in the emergency state 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.
In the case that 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 according to the sequence of the acquisition time, so as to obtain the emergency video. In the case that 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 according to the sequence of the acquisition time, so as to obtain the emergency video. In the case where the target video includes only the first target video, the electronic controller determines the first target video as the emergency video. Referring to fig. 3 again, the electronic controller sequentially splices the second target video 32, the first target video 31, and the third target video 33 to obtain an emergency video 34.
In summary, according to the technical scheme provided by the embodiment of the application, after a vehicle enters an emergency state, three target videos are acquired from a plurality of videos acquired by an image acquisition device in a cyclic recording mode, so that an emergency state video for recording environment information before and after the vehicle enters the emergency state is spliced, and because the videos acquired by the image acquisition device in the cyclic recording mode are multiplexed in the process of acquiring the emergency state video, the video splicing process only consumes a small amount of calculation force 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, and the click feeling 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 video based on time information of the vehicle entering the emergency state. Optionally, the name of the emergency video contains the above-mentioned time information. For example, if the target time for the vehicle to enter an emergency is 2022, 10, 19, and 15 pm 23 minutes, then the name of the emergency video may be "2210191523". By the method, the user can quickly search the emergency video according to the time of the vehicle entering the emergency state, and the searching efficiency is improved.
Further, the vehicle may set the name of the emergency video based on time information of the vehicle entering the emergency state and position information of the vehicle entering the emergency state. The vehicle can acquire the position information of the vehicle in an 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 video includes, in addition to the above-described time information, position information where the vehicle enters an emergency state. In combination with the above example, the vehicle may have a rear-end collision accident at the xx high-speed toll station at 23 pm on the 10/19 th 2022 day, 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 emergency video 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 acquire 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 environment information when the vehicle enters an emergency state, namely, the target video frame is a video frame acquired by the image acquisition device when the vehicle enters the emergency state (namely, the target moment). By the method, when a user views the video cover of the emergency video, the user can quickly know the content of the emergency video.
Referring to fig. 4, a flowchart of a video processing method according to an embodiment of the application is shown. The method comprises the following procedures.
In step S401, N videos are continuously collected by the image collecting device, and the N videos are stored in the first designated folder.

Step S403, in the case that a plurality of target videos exist, performing splicing processing on the plurality of target videos to obtain an emergency video, and storing the emergency video in a second designated folder.
The emergency video is used for recording the environment information of the vehicle before and after entering the emergency. Files in the second designated folder do not respond to the designated deletion instruction, which is other deletion instructions than the user-triggered deletion instruction.
Step S404, after receiving the playing instruction for the emergency video, playing the emergency video.
In some embodiments, the vehicle is provided with a touch-controllable central control screen, the central control screen displays the name of the emergency video, and when a trigger signal for the name of the emergency video is acquired, the electronic controller receives the playing instruction. 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 a play instruction for the emergency video through triggering operation of the operable control. In other embodiments, the play command is a voice signal, the electronic controller collects the voice signal through the sound collection device, and receives the play command when detecting that the voice signal includes a specified keyword.
Step S405, in the process of playing the emergency video, displays a playing progress bar of the emergency video.
The playing progress bar is used for indicating the playing progress of the video in the emergency state. The play progress bar includes a target mark. The target mark is used for marking the video frame acquired by the image acquisition device when the vehicle enters an emergency state.
Referring to fig. 5 in combination, a schematic view of playing an emergency video according to an embodiment of the present application is shown, where a central control screen displays a playing progress bar 51, and the playing progress bar 51 includes a target mark 52 during playing the emergency video.
Step S406, after receiving the trigger signal for the target mark, displaying the video frame acquired 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 of a user aiming at a target mark, and in the embodiment of the present application, only the trigger signal is taken as the single-click trigger signal for illustration. In addition, the trigger signal may also be a voice signal.
In the embodiment of the application, after the user triggers the target mark through the trigger signal, the central control screen jumps to display the video frame acquired by the image acquisition device when the vehicle enters the emergency state, and by adopting the mode, the picture when the vehicle enters the emergency state can be rapidly positioned, and the searching efficiency is improved. Referring again to fig. 5, after the user triggers the target mark 52, the central screen displays the video frame 53 acquired by the image acquisition device when the vehicle enters an emergency state.
In summary, 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 video when the emergency video is played, and after the target mark is triggered by the user, the central control screen jumps to display the video frame acquired by the image acquisition device when the vehicle enters the emergency, so that the rapid positioning of the picture when the vehicle enters the emergency is realized, and the searching efficiency is improved.
In some embodiments, the vehicle further monitors that the ratio of available hardware resources to total hardware resources of the electronic controller is less than a preset ratio, and performs a subsequent video processing step to obtain the emergency video. The preset duty cycle is set experimentally or empirically. The ratio of available hardware resources to total hardware resources of the electronic controller is smaller than the preset ratio, which indicates that the available hardware resources of the electronic controller are insufficient, and at the moment, videos acquired by the image acquisition device in a cyclic recording mode can be multiplexed to reduce calculation force and consumption of the hardware resources of the electronic controller, so that the electronic controller has enough hardware resources to process other services, and the click feeling is reduced.
