This paper first introduces a system which can detect vehicle disobey the red light. then introduces a arithmetic with shadow elimination to solve the problem of violations detection of yellow line: by day,the quality of the image is good,this arthmetic uses a method which combine the line-frame detection and the HSV color information analysis.this method detect violations according as whether the line-frame of yellow is being destroyed. In order to solve the most important problem in apply instance—interference of shadow,we add HSV color information analysis in the area of yellow line which line-frame is being destroyed. If the shadows proportion is below the threshold,then we determine vehicle violative of yellow line; at night,the quality of the image is not good, we calculate the grey image of differences to detect violations.
