Built-in intelligent monitoring system for automatically detecting moving target

Abstract

The invention discloses an embedded intelligent monitoring system for automatically detecting moving target, including a video input device, a visual analysis system and a network input and output device. In order to perform high precision real-time detection of moving targets, the system adopts a method of using a real-time visual analysis algorithm to detect moving targets in real-time, and the method is divided into a training phase and a testing phase; the system will divide the obtained video data into a stable region and a dynamic region in the chrominance brightness spaces, adopting a simple and fast self-adapting single-Gaussian model to the stable region and adopting a computationally complex and effective non-parametric model to the dynamic region. The system has advantages of simple structure, high precision, real-time, strong expandability and multiplex network access function; and can effectively realization real time detecting function of moving target.

Description

technical field [0001] The invention belongs to the field of electronic equipment and relates to an embedded intelligent monitoring system for automatically detecting moving targets. Background technique [0002] With the rapid growth of video surveillance demand and the increasing scale of surveillance, manual surveillance is far from meeting the surveillance requirements, and the "intelligence" of video surveillance systems has become more and more urgent. [0003] The continuous expansion of the monitoring scale and the increasing number of visual analysis tasks have made the centralized visual analysis processing mode based on the PC central server more and more prominent limitations-computer resources and network communication bandwidth are seriously insufficient, and it is increasingly necessary to The front end of the camera performs real-time and efficient local processing on the surveillance video images, and only transmits the relevant alarm status and image data t...
