摘　　要：利用DM642EVM实现对十字路口车辆排队长度的实时检测,给出了系统的软硬原理图。综合灰度检测和边缘检测的优点,提出了一种将灰度与边缘检测相结合的方法来检测队列长度,采用帧平均法来处理视频流,可以减小由于摄像头抖动或背景微小变化而产生的误差。实验结果表明,此方法实现简单,能够获得较满意的检测结果。Using DM642EVM to implement detection of vechide queue length on the crossroads in real-time. The hard and soft principle map was given in the system concerned. Combination of advantages in gray detection and edge detection, a new theory was proposed that combined gray and edge detection to detect queue length. Average frame was used to deal with video streaming, which can reduce the error because of camera shake or small changes in the background. The experimental results expatiated that this method was simple and easy to get more satisfactory results in detection.
