Intelligent video surveillance technology is the total area of machine vision applications of a new direction and leading subject of concern is the computer science, machine vision, image engineering, pattern recognition and artificial intelligence, multi-disciplinary high-tech crystal. Intelligent video surveillance is technically no human intervention could be interpreted as in the case, the use of computer vision and image sequence analysis method, the camera recording the image sequence for automated analysis. When abnormal areas are monitoring the situation, the implementation of the scene identification and tracking of moving targets, and timely and accurate alerts to security personnel. In order to avoid possible criminal, and also to reduce the large number of monitoring staff hiring the required human, material and financial inputs.The purposes of the current situation, intelligent video surveillance, whether in the theoretical aspects or practical applications, there are many problems, domestic many scholars and people with lofty ideals to join the field of research and exploration, and made a lot of fruitful results. In this paper, the analysis and research of these results based on the analysis of some of the key technologies in video surveillance system and achieve. Which mainly include moving object detection and extraction, moving target tracking.Haikang DS-4004H audio and video capture boards using Visual C++, Haikang the SDK, OpenCV, Sql Server2000, modular design, the development of video surveillance systems platform. Moving target detection, tracking and then added to the platform on the basis of simple intelligent video analysis capabilities.This paper first discusses the development of a video surveillance system functional requirements analysis, the overall technical solution, system, and then fixed camera video surveillance system, using an improved fast Gaussian mixture model algorithm, background subtraction method moving target detection,and Kalman filter tracking, moving target tracking.
