Based on the hardware structure of the device, the embodiment of the video anti-clipping method is provided.
Referring to fig. 2, in a first embodiment of the video anti-clip method of the present invention, the video anti-clip method includes:
step S10, generating a target video through the target camera device, and extracting key frames in the target video.
The video anti-clipping method in the embodiment of the invention is applied to a target camera device (hereinafter, a vehicle recorder is used for replacing description), the vehicle recorder can be connected with a local server or a cloud server in an operation state, the local server or the cloud server (hereinafter, the target server is used for replacing description) is used for storing videos shot by the vehicle recorder (namely, target videos in the embodiment), or video related data, after the vehicle recorder shoots the target videos, key frames in the target videos can be firstly extracted by the vehicle recorder, then the target videos are uploaded to the target server, or key frames in the target videos are extracted, and the target videos after the key frames are extracted are uploaded to the target server.
Step S20, splitting the target video based on the key frames to obtain target picture groups, where each target picture group includes one key frame.
In this embodiment, a specific application scenario is provided, the vehicle recorder shoots a target video with a period of 10 seconds, the shooting frame rate of the vehicle recorder is 30 frames per second, the frame number of the target video is 300, the target video is split to obtain 300 frames, the 300 frames are sequenced in sequence according to the time axis of the target video to obtain frames represented by 1 to 300 labels, the position of a key frame in the 300 frames is determined, if the first key frame label of the target video is 2, the second key frame label is 3, and the second key frame label is 6, the first target frame group of the target video comprises frame images with labels 1 and 2, the second target frame group comprises frame images with labels 3 and 4, or frame images with labels 3, 4 and 5, that is, the principle of splitting the target video based on the key frames to obtain target frame groups is that each target frame group only comprises one key frame.
And step S30, sorting the target picture group according to the time axis of the target video to obtain a sorting result, and recording pixel distinguishing information between the key frame and other picture frames in the target picture group.
After 300 frames are sequenced and split in sequence, sequencing the obtained target frame groups according to the time axis of the target video to obtain the sequence of the target frame groups on the time axis of the target video, then recording pixel distinguishing information between key frames and other frame in the target frame groups, and using a first target frame group on the time axis of the target video for illustration, wherein the first target frame group comprises frame frames with the numbers of 1 and 2, the frame with the number of 2 is the key frame in the first target frame group, the frame with the number of 1 is the other frame groups in the first target frame group, and the difference between the frame with the number of 1 and the frame with the number of 2 on the pixel point is recorded to obtain the pixel distinguishing information between the key frame and other frame in the first target frame group; the second target frame group on the time axis of the target video is exemplified, the second target frame group contains frame frames with reference numbers of 3 and 4, or frame frames with reference numbers of 3, 4 and 5, if the second target frame group contains frame frames with reference numbers of 3, 4 and 5, the distinction between any two frame frames with reference numbers of 3, 4 and 5 needs to be recorded (the purpose is to ensure that the distinction record between any two frame frames in the second target frame group is more accurate), thus 6 pieces of pixel distinguishing information are obtained, the pixel distinguishing information obtained by the second target frame group is more, and the storage amount is larger than that of the first target frame group, so that the problem of the quantity of the pixel distinguishing information caused by the distinction is also needed to be comprehensively considered when the target video is split based on the key frames.
And step S40, storing the sorting result and the key frame into the target camera device, and storing the pixel distinguishing information into the target server in an encrypted manner.
After the sorting result of the target picture group on the time axis of the target video is obtained, namely, the sorting result of the key frame on the time axis of the target video is obtained, and then the sorting result of the target picture group on the time axis of the target video, or the sorting result of the key frame on the time axis of the target video and the key frame are stored into a memory of a vehicle recorder together, and the obtained pixel distinguishing information can be stored into a target server in an encrypted manner in consideration of the limited memory of the vehicle recorder, so that the storage pressure of the vehicle recorder is relieved; the method has the advantages that the speed of the automobile data recorder for reading the target video is higher, the key frames are stored in an unencrypted mode, and the aim of encrypting and storing the pixel distinguishing information is that users who cannot decrypt and acquire the pixel distinguishing information cannot acquire complete target video, and then cannot clip the complete target video, so that the safety risk caused by easy clipping of the target video is effectively avoided.
Specifically, the step of refining in step S10 includes:
and a1, acquiring a target video generated by the target camera device, and splitting the target video according to the frame number of the target video to obtain a target picture frame.
And a2, screening the target picture frames according to preset definition and/or preset resolution to obtain key frames in the target video.
In this embodiment, a specific application scenario is given, the vehicle recorder shoots a target video with a period of 10 seconds, the shooting frame rate of the vehicle recorder is 30 frames per second, the frame number of the target video is 300, the target video is split to obtain 300 frames (i.e. the target frame in this embodiment), then, for each frame of the 300 frames, the sharpness value and the resolution value of each frame and the change degree of each frame compared with the previous frame of the frame are calculated, in this embodiment, the change degree of each frame compared with the previous frame of the frame is calculated by using a certain frame of the 300 frames as a first frame, using the previous frame of the first frame as a second frame, obtaining the color value sum of all pixels forming the first frame, and the color value sum of all pixels forming the first frame, calculating the color value sum corresponding to the first frame, and the difference between the color value sums corresponding to the second frame, and the difference between the difference is greater than the change degree of each frame compared with the previous frame. And after calculating the definition value and the resolution value of each frame of 300 frames and comparing the change degree of each frame of frames with the previous frame of frames, weighting the definition value and the resolution value of each frame of frames and the change degree of each frame of frames with the previous frame of frames to obtain the comprehensive score of each frame of frames, and taking the frames with the comprehensive score larger than a certain preset value as key frames.
Specifically, the steps after step a2 include:
and b1, comparing the frame number of the target video with the number of the key frames to obtain a target proportion.
And b2, if the target proportion is smaller than a first preset threshold, reducing the preset definition and/or the preset resolution, and returning to the step of screening the target picture frames according to the preset definition and/or the preset resolution to obtain the key frames in the target video.
And b3, if the target proportion is greater than a second preset threshold, increasing the preset definition and/or the preset resolution, and returning to the step of screening the target picture frames according to the preset definition and/or the preset resolution to obtain the key frames in the target video.
As can be seen from the above, the selection of the key frames has a certain influence on the size of the pixel distinguishing information, so in this embodiment, when the frame number of the target video is obtained and the number of the key frames is extracted based on the preliminarily preset definition threshold, resolution threshold and variation threshold, the ratio of the number of the preliminarily obtained key frames to the frame number of the target video, that is, the target ratio in this embodiment, if the target ratio is smaller than the first preset threshold, it indicates that the number of the preliminarily obtained key frames is smaller than the frame number of the target video, which results in larger pixel distinguishing information, then the preliminarily preset definition threshold, resolution threshold or variation threshold needs to be reduced, and then the target picture frames need to be screened again according to the reduced definition threshold, resolution threshold and variation threshold, so that the number of the key frames obtained by screening is increased; if the target proportion is greater than the second preset threshold, the number of the primarily obtained key frames is larger than that of the target video, so that the number of the key frames which are not stored in an encrypted mode is larger, and the safety risk of the target video being clipped is increased.
Specifically, the steps following step S20 include:
and c1, marking the key frames in the target picture group to obtain key frame identifiers.
The step of refining in the step S30 comprises the following steps:
and c2, sorting the key frame identifiers corresponding to the target picture group according to the time axis of the target video to obtain a sorting result containing the key frame identifiers.
From the above, it can be seen that after the ordering result of the target frame group on the time axis of the target video is obtained, that is, the ordering result of the key frame on the time axis of the target video is obtained, the key frame identifier in this embodiment corresponds to the label of the key frame in the above content, after the label of the key frame is obtained, the label of the key frame is ordered according to the time axis of the target video, so as to obtain the ordering result including the key frame identifier, and the purposes of marking and ordering the key frame are to obtain the ordering result of all the key frames according to the key frame identifier when the key frame is obtained from the memory of the automobile data recorder.
The video clipping prevention method in the embodiment is applied to a target camera, a target server is in communication connection with the target camera, the target camera is used for shooting and generating target videos, key frames in the target videos are extracted, the target videos are split on the basis of the key frames to obtain target picture groups, each target picture group comprises a key frame, the target picture groups are ordered according to a time axis of the target videos to obtain an ordering result, pixel distinguishing information between the key frames and other picture frames in the target picture groups is recorded, finally, the ordering result and the key frames are stored in the target camera, and the pixel distinguishing information is stored in the target server in an encrypted mode.
Further, referring to fig. 3, a second embodiment of the video anti-clipping method of the present invention is presented on the basis of the above-described embodiment of the present invention.
This embodiment is a step of refining step S30 in the first embodiment, and is different from the above-described embodiment of the present invention in that:
step S31, sorting the target picture group according to the time axis of the target video to obtain a sorting result, and judging whether the target picture group contains other picture frames except the key frame.
Step S32, if the target frame group includes the other frame, comparing the key frame in the target frame group with the other frame, and determining a difference pixel point and pixel difference information corresponding to the difference pixel point.
It is known that if a certain target frame group contains only a key frame and does not contain other frame frames except the key frame, the processing of recording pixel distinguishing information is not required for the target frame group, and in fact, the target frame group containing only a key frame does not have corresponding pixel distinguishing information, so that if the target frame group contains only a key frame, only the sorting result and the key frame may be stored in the target image capturing device, and if the target frame group contains other frame frames except the key frame, the key frame in the target frame group is compared with other frame frames to determine distinguishing pixel points and pixel distinguishing information corresponding to the distinguishing pixel points.
Specifically, after the step of generating the target video by the target image capturing apparatus in step S10, it includes:
and d1, when an output instruction corresponding to the target video is detected, extracting a key frame in the target video, and sending the key frame to a target terminal corresponding to the output instruction.
It is known that, in the video anti-clipping method in this embodiment, the target video may be directly stored in the vehicle recorder, then when an output instruction corresponding to the target video is detected, the key frame in the target video is extracted, and the operation in the above embodiment such as the target frame group is obtained by splitting the target video based on the key frame, then the obtained key frame is sent to the target terminal corresponding to the output instruction, and a specific application scenario may be that the target terminal (may be a mobile phone or a personal computer) is in communication connection with the vehicle recorder, when the user obtains the target video from the vehicle recorder through the target terminal and the communication connection, the vehicle recorder detects the output instruction, then the vehicle recorder extracts the target video to obtain the key frame, and then sends the key frame to the target terminal, so that when other users want to obtain the target video through the target terminal, the vehicle recorder may also send the encrypted pixel distinguishing information to the target terminal together, if the other users may decrypt the pixel distinguishing information, the complete target video may be obtained, thereby reducing the pressure of the vehicle recorder and avoiding the risk of clipping the target video from being caused by other vehicle video storage devices.
In this embodiment, by performing the operations such as extracting the key frames when the target video is read from the target image capturing device, the storage pressures of the target image capturing device and the target server are reduced while effectively avoiding the target video from being clipped by the outside.
