Specifically, the setting of the acquisition points of the image acquisition apparatus is not limited to that shown in fig. 1, and may be set according to actual needs, and is not limited thereto, but is illustrated only by way of example in fig. 1.
In particular, the image acquisition device may be any acquisition device known to those skilled in the art that enables rotation, such as, but not limited to, a ball machine, etc., without limitation.
Specifically, an embodiment of the present invention provides a video processing method, as shown in fig. 2, which may include:

The preset video processing rules are described below in connection with specific examples.
For example, taking the application of the video processing method provided by the embodiment of the invention to a traffic intersection scene as an example, an image acquisition device is installed at an intersection, and two acquisition points of the image acquisition device are assumed to be respectively defined as an acquisition point A and an acquisition point B, wherein the acquisition point A can acquire the coming situation in the east-west direction and the acquisition point B can acquire the coming situation in the north-south direction; and, traffic lines, such as stop lines (labeled 1,2, 3, and 4 in the figure), are marked on the ground of the intersection, as shown in fig. 3; then:

That is, different acquisition points, different acquisition ranges and different acquisition scenes, so that corresponding preset video processing rules are different.

Optionally, in an embodiment of the present invention, the initial video stream includes a plurality of video frames, and the video frames and the regular frames each include a category label.
That is, in order to be able to distinguish between the video frame and the regular frame, a category flag may be included in header information of the video frame and the regular frame.
For example, the type mark in the header information of the video frame may be a first mark, and the type mark in the header information of the regular frame may be a second mark, wherein the first mark and the second mark may be at least one of a number, a letter, and a special symbol, and the specific forms of the first mark and the second mark may be set according to actual needs, and are not limited herein.

As shown in fig. 4, when a first video frame S1 corresponding to the acquisition point a is obtained, a regular frame Ga corresponding to the acquisition point a is inserted, and when a second video frame S2 corresponding to the acquisition point a is obtained, the regular frame Ga is set after the regular frame Ga, and then the regular frame Ga is set after the second video frame S2;
Then, the image acquisition equipment rotates to an acquisition point B to continuously acquire video, and when a third video frame S3 is obtained, the third video frame is arranged behind the regular frame Ga;
thus, a regular frame is inserted when a video frame is obtained, so that the target video stream shown in fig. 4 can be obtained.
Of course, only a portion of the target video stream is shown in fig. 4, and not all of the target video stream is represented.
Of course, in the specific implementation, it may also be set as follows: the video frame is positioned behind the corresponding regular frame; that is, the front-rear setting positions of the video frame and the corresponding regular frame may be set according to actual needs as long as the insertion of the regular frame into the initial video stream can be achieved.
Based on the same inventive concept, an embodiment of the present invention provides a video processing method, as shown in fig. 6, applied to a video processing apparatus, the method including:

S602, extracting a regular frame and an initial video stream;
S603, performing video processing on the extracted initial video stream according to a preset video processing rule included in the extracted rule frame.
In this way, the image acquisition equipment determines the target video stream, so that the target video stream can comprise a rule frame corresponding to a preset video processing rule, further the image acquisition equipment can send video data and the preset video processing rule to the video processing equipment through a transmission channel, and when the video processing equipment performs video processing, the rule frame corresponding to the video data can be accurately determined, thereby realizing accurate processing of the video data, increasing the perceived instantaneity of the target video stream and the preset video processing rule, avoiding the problem that the preset video processing rule and the video stream are not synchronous, and improving the accuracy and the effectiveness of a video processing result; in addition, the method provided by the embodiment of the invention can be also suitable for processing the video, solves the problem that the video cannot be dynamically configured with the preset video processing rule, and has a wider application range.

Extracting the rule frame according to the category marks included in the rule frame;
And extracting the video frame according to the category marks included in the video frame to obtain an initial video stream.
In this manner, regular frames and video frames may be extracted from the target video stream based on the category labels, for subsequent video processing of the video frames according to the regular frames.
Optionally, in an embodiment of the present invention, performing video processing on the extracted initial video stream according to a preset video processing rule included in the extracted rule frame includes:
The target video stream comprises: when a plurality of video frames and a plurality of regular frames, the following procedure is performed for each regular frame:
Judging whether the currently extracted rule frame is the first rule frame in the target video stream or not;
