The video encoder is further configured to perform first processing on the N paths of first surveillance video streams to obtain a second surveillance video stream, and send the second surveillance video stream to the video management client through UDP connection, where the second surveillance video stream includes the N paths of first surveillance video streams.
Wherein the first processing includes the steps of: splicing the N paths of first monitoring video streams to obtain a third monitoring video stream; reducing the resolution of the third monitoring video stream according to a preset proportion to obtain a fourth monitoring video stream; and coding the fourth monitoring video stream to obtain the second monitoring video stream.
When the video stream is spliced by adopting the splicing technology, images of current frames of different video streams can be spliced.
Optionally, splicing the N first surveillance video streams includes:
obtaining N first images based on the N first monitoring video streams, wherein the N first monitoring video streams correspond to the N first images one by one, and each first image is a current frame image of the corresponding first monitoring video stream;
performing vehicle identification on the N first images, determining M second images, S third images and T fourth images in the N first images, wherein each second image does not include vehicle image information, each third image includes the vehicle image information but does not include the license plate image information, each fourth image includes the license plate image information, the sum of the S, the T and the M is the N, and the S, the T and the M are integers;
determining a first size of the M second images, a second size of the S third images, and a third size of the T fourth images based on the T, the S, and the M;
and splicing the M second images, the S third images and the T fourth images based on the first sizes of the M second images, the second sizes of the S third images and the third sizes of the T fourth images.
Optionally, the determining the first sizes of the M second images, the second sizes of the S third images and the third sizes of the T fourth images based on the T, the S and the M includes:
determining a first size of the M second images based on a first formula, the T, the S, and the M;
determining a third size of the T fourth images based on a second formula, the T, the S, and the M;
determining a second size of the S third images based on a third formula, the T, the S, and the M.
The first formula is L1 ═ L (a1/(a1+ a2+ A3) -a) ×, where L1 is the first size of M second images, a1 is the number of second images, a2 is the number of third images, A3 is the number of fourth images, a is a parameter and can be set according to actual conditions, and L is the size of display permission.
The second formula is L3 ═ L (A3/(a1+ a2+ A3) + a) ×, where L3 is the third size of T fourth images, a1 is the number of second images, a2 is the number of third images, A3 is the number of fourth images, a is a parameter and can be set according to actual conditions, and L is the size of display permission.
Wherein the third formula is L2 ═ L-L1-L3, the L2 is the second size of the M third images, the L1 is the first size of the M second images, the L3 is the size of the T fourth images, and the L is the size that allows display.
For example, if there are 3 first surveillance video streams (#1, #2, #3, and #4), picture # T1 is available through #1, picture # T2 is available through #2, picture # T3 is available through #3, and picture # T4 is available through # 4. Since it is found that # T1 does not include vehicle image information after vehicle identification in # T1, # T2, and # T3, # T2 includes vehicle image information but does not include license plate information, # T3, and # T4 include vehicle image information. Assuming that a is 0.2, the image # T1 occupies 5% of the size of the permitted display, # T2 occupies 25% of the size of the permitted display, and # T3 and # T4 together occupy 70% of the size of the permitted display.
Alternatively, after the size of the S third images, the area occupied by the vehicle imagery in each third image may be determined, and the size of each third image may be determined based on the area occupied by the vehicle imagery, wherein determining the size of each third image may be the same as the method of determining the size of the S third images.
Optionally, after the size of the T fourth images, the area occupied by the license plate image in each fourth image may be determined, and the size of each fourth image may be determined based on the area occupied by the license plate image, wherein determining the size of each fourth image may be the same as determining the size of the T fourth images.
The size of the current frame image can be determined according to the image information in the current frame image of the video stream, so that the application range of the video encoder can be favorably expanded.
Alternatively, the size of the image may be determined based on the type of vehicle in the image, including a van, a sedan, a tractor, and the like.
Alternatively, the first processing may be dynamically adjusting the resolution of each first surveillance video stream based on the recognition result of the image in each first surveillance video stream, and splicing the resolution-adjusted first surveillance video streams.
Taking a 4-channel vehicle video stream of a traffic road as an example, the adjustment can be performed based on the recognition result of the target object, i.e. the vehicle.
Optionally, the first processing includes the steps of: if the area or the ratio of the image information of the vehicle contained in the first channel image and the second channel image which are processed currently is detected to be larger than or equal to a preset threshold value, determining the first resolution of the corresponding image according to the area or the ratio;
if the area or the ratio of the currently processed third channel image and fourth channel image in the image set, which contain the vehicle image information, is smaller than a preset threshold value, adopting a preset second resolution;
and adjusting the four-channel images according to the determined first resolution and the second resolution, and splicing the adjusted four-channel images.
The detection can be periodic detection, the period can also be dynamically set, and the extension is expanded according to the needs, because the period is too small, the computation amount is greatly delayed and improved, and the resolution of the image displayed by the video management client is changed too fast.
The video encoder can adjust the resolution according to the currently processed image, so that the application range of the video encoder is favorably expanded.
It can be seen that, in the embodiment of the present application, first, a video management client sends a first monitoring video-on-demand request to a video management server, where the first monitoring video-on-demand request carries a first IP address of the video management client and an identifier of N first target channels, the first monitoring video-on-demand request is used to request to simultaneously on-demand N first monitoring video streams, then the video management server receives the first monitoring video-on-demand request, determines a video encoder in a monitoring video-on-demand table of the video management server based on the first IP address, sends first indication information to the video encoder, where the first indication information is used to indicate the video encoder to perform first processing on the N first monitoring video streams, so as to obtain a second monitoring video stream, and sends the second monitoring video stream to the video management client through user UDP connection. The first processing is to splice the N paths of first monitoring video streams to obtain a third monitoring video stream, then reduce the resolution of the third monitoring video stream according to a preset proportion to obtain a fourth monitoring video stream, and finally encode the fourth monitoring video stream to obtain the second monitoring video stream.
In an implementation manner of the present application, after the video encoder sends the second surveillance video stream to the video management client through a UDP connection, the video management client is further configured to receive the second surveillance video stream and display the second surveillance video stream;
the video management client is further configured to send a second monitoring video-on-demand request to the video management server under the condition that a first operation instruction is received, where the first operation instruction is used to instruct to individually display a first monitoring video stream in a second target channel, the N first target channels include the second target channel, the second monitoring video-on-demand request carries an identifier of the second target channel, and the second monitoring video-on-demand request is used to request to individually request to individually request to play the first monitoring video stream in the second target channel;
the video management server is also used for receiving the second monitoring video-on-demand request;

And under the condition that the first operation instruction is a click instruction, receiving the first operation instruction in a screen range occupied by the first monitoring video stream of the second target channel.
And the video management client only displays the first monitoring video stream in the second target channel.
