| 摘 要： | 基于车头灯对的夜间车辆检测是智能视频监控系统的一个关键技术.夜间车辆检测的难点在于光照条件差的情况下有效信息提取困难,而夜间亮度条件差却又使得车头灯部件形成明显的亮块,因此夜间车辆检测算法中可选取车头灯对作为车辆目标的部件特征.通过获取到视频图像的逆投影图,以及逆投影图中车头灯亮块的几何形状特征,与现实中车辆车头灯几何特征一致,并利用几何特征完成夜间车辆车头灯部件的检测,最终给出车辆检测结果.

| Abstract: | Vehicle detection based on vehicle front light is a key technology of intelligent video surveillance system. The difficulty of vehicle detection in the night is to extract the effective information from the poor light conditions, and the night light condition is bad, but the light intensity of the vehicle can form a clear bright block, so the vehicle detection algorithm can choose the car front light as a part of the vehicle target.In this paper, we obtain the geometric characteristics of the front light block of the video images, and then use the geometric features to finish the detection of the front light components of the vehicle. |

| Keywords: | vehicle front light vehicle detection component characteristics inverse projection |
