Data packing method for video analysis system communication

Abstract

The invention discloses a data packing method for video analysis system communication. The method comprises acquisition ends, a transmitting end and a user terminal, wherein the acquisition ends are used for acquiring and coding intelligent video metadata; the transmitting end is used for packing the video metadata of different acquisition ends, and then transmitting data packets to the user terminal; and the user terminal is used for parsing the intelligent metadata, extracting moving targets and presenting alarm information. The method comprises the following steps: I, acquiring video intelligent metadata with the acquisition ends being video intelligent data acquisition modules of different manufacturers; and II, acquiring the intelligent metadata through interfaces provided by the manufacturers, packing the metadata, and transmitting packets to the user terminal through a certain protocol. Through adoption of the data packing method, intelligent applications such as moving target search and video abstract retrieval can be performed more rapidly in mass video information, and extension can be performed flexibly according to the types of actual video analysis applications. The data packing method has high expansibility and compatibility.

Description

technical field [0001] The invention relates to the field of video analysis, in particular to a data grouping method for communication of a video analysis system. Background technique [0002] The use of video analytics for security and surveillance is gaining popularity. Video analysis has developed from an initial PC-based application to multiple devices (such as cameras, encoders, storage, etc.) that can be embedded in video platforms. Intelligent video analysis can automatically analyze and extract key information from video sources, which greatly improves the efficiency of video surveillance. However, in practical applications, the video intelligent analysis system must be compatible with the intelligent analysis equipment or intelligent analysis platforms of many manufacturers. The data interface of the system is not consistent, and the forms of intelligent metadata received by the system are diversified, which cannot satisfy the stable and efficient communication bet...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a data grouping method for video analysis system communication, which solves the problem that in the prior art, there are large differences in the format of intelligent metadata collected by video analysis equipment from various manufacturers, and a large amount of time and physical resources are consumed in actual application. The video analysis and communication data grouping method provided, when data grouping, describes the intelligent information of the metadata through the multi-dimensional description composed of the time information, target information and alarm information of the metadata, so as to more quickly carry out such activities in massive video information Intelligent applications such as target search and video abstract retrieval, and at the same time, the communication grouping method provided by the present invention can be flexibly expanded according to the type of actual video analysis application, and has good scalability and compatibility
