| 摘 要： | 采用2个相同的图像传感器采集周围物体的图像信息,然后利用相关原理得到车辆运行速度的视频测速方法,可直接测量车体相对周围静止物体的速度,由此解决车辆速度测量问题.其测速误差分析包括:通过精确测定或增大2传感器间距离以减小距离误差,及通过增大CCD摄像频率以减小时间误差.

| Abstract: | Adopt two same image sensor to gather the image environment information. Then, make use of correlation theory to acquire the video measurement method for vehicle velocity. After that, directly measure the velocity of vehicles relative to the static objects. By this means, solve the problem of velocity measurement of vehicles. The measurement velocity analysis includes to minish the distance error by accurately measuring or increasing the distance between the two image sensors, and to minish the time error by increasing the frequency of CCD. |
