The method has extended the image unwarping capability of the existing methods for SVP omni-cameras to tolerate lens/mirror assembly imprecision, which is difficult to overcome in most real applications.

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.

本算法在白天图片质量较好时，采用结合HSV颜色空间分析线结构检测算法，该算法利用黄线区域的边缘结构特征作为依据检测是否存在车辆或阴影压黄线，针对实际应用中存在的最大问题即阴影的干扰，加入了HSV颜色空间分析来检测黄线边缘残缺区域，若该位置阴影比重低于一定比例，才认定为是车辆压黄线违章而不是阴影干扰；在夜晚图片质量下降的时候，采用灰度差值法。
