The invention discloses a vehicle speed matching method based on linear array CCD image, including the following steps that: two linear array CCD video cameras are respectively arranged on two sections positioned on a road at intervals; both linear array CCD video cameras face downwards and are provided with infrared ray laser source; the frame rate of each CCD video camera is more than 1,000 frames per second, and the resolution is more than 1,024 lines; correlation matching computation of the image sequences obtained by both linear array CCD video cameras is carried out to obtain the time difference of the same object in two image sequences; finally, by means of the time difference and the distance between both cameras, the driving speed of an object vehicle can be obtained according to the velocity formula V=s/t.
本发明公开了一种基于线阵CCD图像的车辆速度匹配方法,该方法在道路相距一定距离的两个断面上分别安装两个线阵CCD摄像机,两个线阵CCD摄像机指向垂直向下,线阵CCD摄像机上配有红外线激光源,线阵CCD摄像机的帧速率大于1000帧/秒,分辨率大于1024线;对两个线阵CCD摄像机得到的图像序列进行相关匹配计算,从而获得同一个目标在两个图像序列中的时间差,利用该时间差和两个摄像机的距离,根据速度公式V=s/t即可以得到目标车辆的行进速度。
