Problems solved by technology

[0006] The existing solution adopts the post-analysis method. After the IPC stores the video stream to the storage server, and then periodically analyzes the intelligent data, it can only process the historical stream; and the data storage by the IPC also has a certain periodicity and is not real-time. Storage, the video data that has been collected by the IPC but has not been stored in the storage server cannot be analyzed
Moreover, the analysis of all IPC video streams is completed by an independent video analysis server, which has a huge workload and takes a long time, which increases the technical difficulty of the video analysis server
It can be seen that the existing solutions for storing video data and intelligent data have the disadvantage of poor timeliness

example 1

[0069] Example 1. Target crossing line:

[0070] Figure 5 In the figure, the thick line is the drawing of the user on the playback screen, the search rule: the moving object moves from the left to the right of A1A2, and passes through B1B2; the thin line in the figure is the alarm rule: the moving object moves from the left to the right of M1M2, and After N1N2; the intelligent calculation component combines the motion trajectory information contained in the intelligent data to perform geometric calculations to determine whether the target that meets the alarm rule (its motion coordinates can be obtained through the motion trajectory information) also meets the retrieval rule, and if so, extract the corresponding intelligent data. time point, execute step 407; otherwise, do not extract the time point. When the user draws on the playback screen, only the drawn lines about the retrieval rules are displayed; Figure 5 The line drawing of the search rule and the alarm rule is di...

example 2

[0071] Example 2. Target invasion area:

[0072] Image 6 In the figure, the dotted line part is the user’s drawing in the playback screen, the retrieval rule: the moving target enters the dotted line frame from outside the dotted line frame; the solid line part in the figure is the alarm rule: the moving target enters the solid line frame from outside the solid line frame; the intelligent computing component performs geometric Calculate and determine whether the target that satisfies the alarm rule also satisfies the retrieval rule, if yes, extract the time point in the corresponding smart data, and execute step 407; otherwise, do not extract the time point. like Image 6 In the instance of , the target whose motion trajectory is in the shaded part satisfies the retrieval rules at the same time.

example 3

[0073] Example 3. The target item is missing:

[0074] Figure 7 In the figure, the dotted line part is the drawing of the user in the playback screen, the search rule: the moving object enters the dotted line frame from outside the dotted line frame and leaves behind items; the solid line in the figure is the alarm rule: the moving object enters the solid line frame from outside the solid line frame and misses The object is found; the intelligent computing component performs geometric calculation to determine whether the object satisfying the alarm rule also satisfies the retrieval rule, if so, extracts the time point in the corresponding intelligent data, and executes step 407; otherwise, the time point is not extracted. like Figure 7 In the example of , the object whose motion trajectory is in the shaded part satisfies the retrieval rules at the same time; in the figure, moving object A carries item B into the area, and item B is missed. Missing items about moving object...

Abstract

The present invention discloses an intelligent processing method and system of video data. According to the method, an alarm rule is set at an intelligent camera. The method comprises the steps that the intelligent camera carries out video data collection, analyzes the collected video data in real time, and generates intelligent data if the alarm rule is satisfied, and the intelligent data comprises an encoder identification and movement trajectory information; the intelligent camera capsulates the video data and the intelligent data together to be data stream and sends the data stream to the frame analysis component in a cloud storage system; the frame analysis component decapsulates the received data stream, obtains the video data and the intelligent data, and the video data and the intelligent data are stored in a storage component; the storage component sends the storage addresses of the video data and the intelligent data to an index server to carry out respective recording. According to the scheme of the invention, the collected video data can be intelligently processed in real time.

Description

technical field [0001] The invention relates to video processing technology, in particular to an intelligent processing method and system for video data. Background technique [0002] In the existing intelligent processing scheme of video data: each network camera (IPC, IP camera) collects video data, and sends the video stream to a network storage server for storage. [0003] Then, the user can read the video data from the storage server and play it. During the playback process, feature requirements can be set to extract video data that meets the requirements combined with intelligent information for playback, thereby improving the efficiency of video search and realizing intelligent processing. The feature requirement is the feature information of the moving target in the image, such as all the video data of the moving vehicle in the image. [0004] The intelligent processing scheme of the existing video data is specifically implemented in the following ways: [0005] A...
