Research and application of image recognition technology based on dynamic projection principle

On the basis of research of image recognition and process, a video enforcement system for cars running red light was designed with dynamic projection technology. In this system,recognition was achieved by threshold of the difference of gray scales according to RGB gray scale variation of a video detector. The background refreshing technology was adopted corresponding to variation of background, so as to guarantee the reality of the background signal and perform vehicle recognition well. At the same time, the design of hardware circuit and software of front detector controller were completed. Experiements prove that this system has good practicality.
