Abstract

Abstract: Based on the introduction of image identification，this paper puts forward the method of grid conversion and then establishes the rela． fionship between file image coordinate and tile plane coordinate．Thus the traveling track of the runing vehicle in the image can be got,so that it can get the rea1-time speed and position of the vehicle，and achieve the purpose of traffic information collection．

Key words: image manipulation, grid conversion, traveling track, traffic information collection

摘要： 笔者在文中简要介绍了图像识别的基础上，提出了网格转换方法，在图像坐标和道路平面投影坐标之间建立关系，获取运动车辆的行驶轨迹，从而得到车辆的实时车速和位置，达到交通信息采集的目的．

关键词: 图像处理, 网格转换, 行驶轨迹, 交通信息采集
