Intelligent video surveillance technology is a new technology in recent years, which uses computer vision technology, artificial intelligence technology and digital video processing technology to identify the target of surveillance video, through the analysis and processing of this, so as to control the video surveillance system, intelligent video surveillance technology is a relatively complex subject. In particular, the recognition, detection and tracking display of moving objects is a hot research issue in the field of intelligent video surveillance. How to accurately identify object features in a complex environment is still a difficulty in this field.
With the development of micro-electronic technology and embedded system in our country, the current industry relatively traditional traffic lights can not meet customer needs. In order to improve the traditional traffic lights in the control of the short board problem, in this graduation design, will use relatively advanced, fast, intelligent control mechanism. The control brain of the system is the core controller 51 series embedded development system, which mainly uses digital control technology to convert the input continuous analog voltage signal into discrete digital signal, which is transmitted to the LCD. The traffic light design has intelligent control, digital display and other functions, and cost-effective, accurate, low energy consumption, simple production, weighing convenient and fast characteristics, to peoples lives has brought a great impact on the market is very popular.
This paper mainly discusses and proposes a video surveillance system to collect the road through the vehicle image information, on the basis of three video surveillance algorithms optical flow method, frame difference method, background difference method, calculation monitoring road traffic flow, according to the traffic flow and the coordination of the lower machine, reasonable allocation of traffic light time, in order to slow down the traffic pressure, in order to more quickly and more quickly the road traffic. In order to verify the design system, in the experimental stage, a set of simulation verification model is developed based on the embedded platform. The same core image processing algorithm is used to carry out experimental verification on the embedded platform and the upper computer platform respectively, and good results are obtained.
The intelligent control system design mainly from the domestic and foreign development status, hardware control components selection, according to the control principle to draw the hardware circuit, control system software programming and development are explained in detail. The control system uses STC89C52RC embedded development system, circuit display part, key circuit and so on to form intelligent traffic light control system.
