In recent years, various video surveillance needs continues to heat up . Life , base station monitoring residential security monitoring , telecommunications industry , banking system, ATM monitoring , forestry department fire monitoring , transport illegal , traffic monitoring and so on . August 8, 2008 , the success of the Olympic Games in Beijing held high demands for security , help to meet these requirements largely to the aid of a computer monitoring system . Functionally speaking , the video surveillance for security to prevent access to information and command and dispatch . Although surveillance cameras have been widely exist in places such as banks , shopping malls , parking lots and traffic junctions , but the existing video surveillance systems , usually just record a video image , used as a post- evidence , did not give full play to the real-time active monitoring role . To conduct real-time monitoring staff are to face a number of screen manual monitoring , manual operation . This operation is not only time-consuming, laborious , and focus people 's attention on the limited time there will be a lot of loopholes . To improve the existing video surveillance system to monitor targets automatic detection and extraction, identification, tracking, motion analysis and understanding , you can save a lot of manpower and material resources , a great convenience to all aspects of social life . So research on intelligent video monitoring technology has important theoretical and practical significance . Based monitoring of computer vision without the need for human intervention , the use of computer vision and video analysis method for automatic analysis of the image sequence of camera recording , locate , identify and track targets in the dynamic scene , and on this basis analyze and judge the behavior of the target , which not only completion of the day-to-day management and can promptly respond to the abnormal situation occurs . In this thesis , in a study based on the theory of video surveillance , video surveillance of road . Based on the the computer visual surveillance system not only conforms to the development trend of the future of the information industry , and represents the future development direction of the surveillance industry presents tremendous business opportunities and economic benefits by academia, industry , and management departments attach great importance .
