When the front-end camera sends a video stream to the video processing device, the video stream is transmitted through a single video transmission channel, and the number of the acquisition point or the processing rule is transmitted through other transmission channels, so that the processing rule determined by the video processing device may be out of synchronization with the video stream, that is, the video of the acquisition point a, which is aimed at by the video stream currently received by the video processing device, and the determined processing rule may correspond to the acquisition point B, which may cause an error in the result of video processing.

The following describes in detail a specific implementation of a video processing method and apparatus according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, an image capturing apparatus is introduced, as shown in fig. 1, the image capturing apparatus is provided with a plurality of capturing points, such as points a, B, and C shown in fig. 1, and the setting position of the image capturing apparatus may be maintained unchanged, but may be rotated between the capturing points (as indicated by the dotted arrows in fig. 1, the rotation is between the capturing points, and the rotation direction is not limited to the dotted arrows), so as to capture videos of different angles and different scenes.
Specifically, the arrangement of the capturing point of the image capturing device is not limited to that shown in fig. 1, and may be set according to actual needs, and is not limited herein, and is only illustrated in fig. 1 as an example.
Specifically, the image capturing device may be any capturing device known to those skilled in the art to implement rotation, such as, but not limited to, a ball machine, and the like, and is not limited thereto.
Specifically, an embodiment of the present invention provides a video processing method, as shown in fig. 2, which may include:
s201, when any acquisition point is reached, determining a preset video processing rule corresponding to the acquisition point according to the corresponding relation between the preset acquisition point and the preset video processing rule;
the preset video processing rules corresponding to each acquisition point can be preset according to the acquisition range, the acquisition scene and the video processing requirements corresponding to the acquisition point, and specific preset video processing rules are not specifically limited herein.
The following describes the preset video processing rule with reference to a specific example.
For example, taking the application of the video processing method provided by the embodiment of the present invention to a traffic intersection scene as an example, an image acquisition device is installed at the intersection, and it is assumed that two acquisition points of the image acquisition device are defined as an acquisition point a and an acquisition point B, respectively, where the acquisition point a can acquire the incoming traffic situation in the east-west direction, and the acquisition point B can acquire the incoming traffic situation in the north-south direction; and, traffic lines such as stop lines (marked with 1, 2, 3 and 4 in the drawing) are marked on the ground of the intersection as shown in fig. 3; then:
the preset video processing rule corresponding to the acquisition point a may include:
identifying a red light in a traffic light (not shown in the figures);
when a straight line (denoted as a broken line M1) that coincides with the stop line 1 and the stop line 2 is provided, a vehicle that has passed over the stop line 1 and the stop line 2 is identified.
Thus, when performing video processing, the video processing apparatus can perform the following processes:
judging whether a vehicle crosses the stop line 1 and the stop line 2 when the red light is on in the video corresponding to the acquisition point A;
if the vehicle running the red light exists, the license plate number of the vehicle running the red light in the video can be identified, so that the vehicle can be punished to run the red light in the following process.
Likewise, the preset video processing rule corresponding to the acquisition point B may include:
identifying a red light in a traffic light;
when a straight line (denoted as a broken line M2) that coincides with the stop line 3 and the stop line 4 is provided, a vehicle that passes over the stop line 3 and the stop line 4 is identified.
Thus, when performing video processing, the video processing apparatus can perform the following processes:
judging whether a vehicle crosses the stop line 3 and the stop line 4 when the red light is on in the video corresponding to the acquisition point B;
if the vehicle running the red light exists, the license plate number of the vehicle running the red light in the video can be identified, so that the vehicle can be punished to run the red light in the following process.
The dotted line M1 is a straight line parallel to the north-south direction in fig. 3 because it is suitable for the vehicle coming in the east-west direction, and the dotted line M2 is a straight line parallel to the east-west direction in fig. 3 because it is perpendicular to the east-west direction, so the dotted line M1 and the dotted line M2 are perpendicular.
That is to say, different acquisition points have different acquisition ranges and different acquisition scenes, so that the corresponding preset video processing rules are different.
S202, processing the determined preset video processing rule to obtain a rule frame corresponding to the acquisition point;
s203, when the video data collected at the collection point is coded into an initial video stream, inserting the regular frame corresponding to the collection point into the initial video stream to obtain a target video stream;
specifically, the initial video stream may include a plurality of video frames, wherein the structures of the regular frames and the video frames may be set as: the TLV (tag Length value) structure, so that when the preset video processing rule is processed, any processing method that can be implemented to be encoded into the TLV structure, which is well known to those skilled in the art, may be used, and the specific processing procedure is not limited herein.
S204, sending the target video stream to video processing equipment; wherein the target video stream is to: the video processing device extracts a regular frame and an initial video stream in the target video stream, and performs video processing on the extracted initial video stream according to a preset video processing rule included in the extracted regular frame.
Therefore, the target video stream is determined through the image acquisition equipment, so that the target video stream can comprise the regular frames corresponding to the preset video processing rules, the image acquisition equipment can send the video data and the preset video processing rules to the video processing equipment through one transmission channel, when the video processing equipment carries out video processing, the regular frames corresponding to the video data can be accurately determined, the accurate processing of the video data is realized, the real-time perception of the target video stream and the preset video processing rules is improved, the problem that the preset video processing rules are not synchronous with the video stream is avoided, and the accuracy and the effectiveness of the video processing result are improved; in addition, the method provided by the embodiment of the invention can also be suitable for processing the video, and solves the problem that the video cannot dynamically configure the preset video processing rule, so that the method has a wider application range.
Optionally, in an embodiment of the present invention, the initial video stream includes a plurality of video frames, and each of the video frames and the regular frames includes the 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 the header information of the video frame and the regular frame.
For example, the category flag in the header information of the video frame may be a first flag, and the category flag in the header information of the regular frame may be a second flag, where the first flag and the second flag may be at least one of a number, a letter, and a special symbol, and the specific form of the first flag and the second flag may be set according to actual needs, and is not limited herein.
Therefore, the regular frames and the video frames can be extracted from the target video stream based on the category labels, so that the video processing can be performed on the video frames according to the regular frames.
Optionally, in this embodiment of the present invention, inserting the regular frame corresponding to the acquisition point into the initial video stream to obtain the target video stream specifically includes:
when the initial video stream corresponding to each acquisition point comprises a plurality of video frames, inserting the regular frames corresponding to the acquisition points into the initial video stream at intervals of N video frames to obtain a target video stream;
wherein N is a positive integer.
Specifically, the value of N may be set according to actual needs, for example, but not limited to, the value of N is 1, 2, or 3, and the like, and is not limited herein.
Therefore, regular frames can be inserted between the initial video streams according to a certain frequency to form a target video stream, so that the video processing equipment can perform accurate and effective video processing.
Specifically, in the embodiment of the present invention, as shown in an enlarged structural diagram within a dashed box 1 in fig. 4, a video frame may include: i-frames and P-frames.
For example, as shown in fig. 4, the video frame S may include an I frame and a plurality of P frames, and the arrangement order of the I frame and the P frames in each video frame is the same.
Therefore, the consistency of the structures of the video frames can be ensured, so that the video data can be decoded based on the video frames, and the subsequent video processing is facilitated.
Of course, in practical cases, the video frames may also include B frames, and the B frames may be located between the I frames and the P frames, as shown in fig. 5, and the arrangement order of the I frames, the B frames, and the P frames is the same in each video frame.
The target video stream is exemplified below.
For example, as in the target video stream shown in fig. 4, assume that: the image capturing device is provided with two capturing points, which are respectively marked as a capturing point a and a capturing point B, the image capturing device rotates back and forth between the capturing point a and the capturing point B, the time spent at each capturing point may be the same (correspondingly, the number of video frames corresponding to each capturing point is also the same), and of course, the time spent at each capturing point may also be different (correspondingly, the number of video frames corresponding to each capturing point is different), fig. 4 illustrates the case where the time spent at each capturing point is the same, but the invention is not limited thereto.
As shown in fig. 4, when the first video frame S1 corresponding to capture point a is obtained, the regular frame Ga corresponding to capture point a is inserted, when the second video frame S2 corresponding to capture point a is obtained, it 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 the video, and when a third video frame S3 is obtained, the third video frame is arranged behind the regular frame Ga;
in this way, 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 shown.
Of course, in specific implementation, the following may also be set: the video frame is positioned behind the corresponding regular frame; that is, the positions of the video frame and the corresponding regular frame can be set according to actual needs, as long as the regular frame can be inserted into the initial video stream.
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 device, the method including:
s601, acquiring a target video stream; wherein, the target video stream is: when the image acquisition equipment reaches any one of a plurality of preset acquisition points, a preset video processing gauge corresponding to the acquisition point is determined according to the corresponding relation between the preset acquisition point and a preset video processing ruleThenProcessing the determined preset video processing rule to obtain a rule frame corresponding to the acquisition point; when the video data collected at the collection point is coded into an initial video stream, inserting the regular frame corresponding to the collection point into the initial video stream to obtain a target video stream;
s602, extracting a rule frame and an initial video stream;
and S603, performing video processing on the extracted initial video stream according to a preset video processing rule included in the extracted rule frame.
Therefore, the target video stream is determined through the image acquisition equipment, so that the target video stream can comprise the regular frames corresponding to the preset video processing rules, the image acquisition equipment can send the video data and the preset video processing rules to the video processing equipment through one transmission channel, when the video processing equipment carries out video processing, the regular frames corresponding to the video data can be accurately determined, the accurate processing of the video data is realized, the real-time perception of the target video stream and the preset video processing rules is improved, the problem that the preset video processing rules are not synchronous with the video stream is avoided, and the accuracy and the effectiveness of the video processing result are improved; in addition, the method provided by the embodiment of the invention can also be suitable for processing the video, and solves the problem that the video cannot dynamically configure the preset video processing rule, so that the method has a wider application range.

extracting the rule frame according to the category mark included in the rule frame;
and extracting the video frames according to the category labels included in the video frames to obtain an initial video stream.
Therefore, the regular frames and the video frames can be extracted from the target video stream based on the category labels, so that the video processing can be performed on the video frames according to the regular frames.

Therefore, if the currently extracted regular frame is the first regular frame in the target video stream, it is indicated that the preset video processing rule is not decoded yet, so that the first regular frame needs to be decoded to obtain the corresponding preset video processing rule, and then the corresponding video data is subjected to video processing based on the preset video processing rule;
if the current extracted regular frame is not the first regular frame in the target video stream, the rule frame is extracted before the current extracted regular frame is indicated, so that the current extracted regular frame can be compared with the last extracted regular frame, and if the current extracted regular frame and the last extracted regular frame are the same, the current video frame and the last video frame needing to be processed are indicated to correspond to the same acquisition point, so that the current extracted regular frame does not need to be decoded, and the last decoded preset video processing rule can be directly adopted, so that the step of decoding can be omitted, the speed of video processing is increased, the calculation amount of video processing is reduced, and the manufacturing cost of video processing equipment is reduced;
if the two are different, it is indicated that the current video frame and the last video frame to be processed correspond to different acquisition points, so that the determined preset video processing rule needs to be updated, that is, the current extracted rule frame needs to be decoded to obtain a new preset video processing rule, and then video processing is performed based on the new preset video processing rule, so that the accuracy of video processing can be increased, and processing errors are avoided.
It should be noted that, optionally, in an embodiment of the present invention, the target video stream may include: the real-time video stream sent by the image acquisition equipment or the pre-stored video stream.
That is, the target video stream to be processed by the video processing device may be a real-time video stream transmitted by the image capturing device, and may also be a video stream transmitted by the image capturing device before, but stored by the video processing device without being processed immediately.
