Abstract

The invention aims to disclose an intelligent web camera with a video structural description function, which is characterized by comprising a video structural description device for carrying out structural description processing on video information, wherein the video structural description device comprises an image collecting unit, an analysis and discrimination unit and a description unit. The web camera of the invention can complete a network monitoring function, directly analyze and understand the shot monitoring video, and generate structural description information about the attribute and content of the video images; the description information has a small data volume and can be stored and transmitted through network conveniently; and by retrieving and querying the description information, the searched video images can be found quickly, thereby greatly improving the utilization efficiency of the video information, reducing the cost of manual retrieval and searching, and realizing the purpose of the invention.

Description

technical field [0001] The invention relates to an intelligent network camera, in particular to an intelligent network camera with video structured description function. Background technique [0002] With the development of embedded technology and network technology, the monitoring system has gradually developed from the traditional closed-circuit television (CCTV) monitoring system to the direction of network and intelligence. [0003] The network camera is designed for the monitoring needs in the network environment. It overcomes the shortcomings of the traditional CCTV monitoring system that cannot obtain video information through the network. Users can watch, record and manage video information through any computer in the network. [0004] Network camera is a fully digital monitoring device, it is based on the standard TCP / IP protocol, can be transmitted through LAN / wireless network / Internet, its image resolution can generally reach 2 to 5 million pixels, and the clarity...
