| Abstract: | The microscopic traffic data has important meanings for highway capacity analysis, establish- ment of ITS, abnormal traffic status identification, features research of microscopic traffic flow and devel- opment of microscopic traffic simulation. The increasing of video acquisition technology application in the field of traffic and the development of the image processing technology make it possible to obtain micro- scopic traffic data. In this paper, by using the theory of photography, it realizes the transformation of im- age coordinate and the actual coordinate and has extracted the movement tracks, speed and headway of ve- hicles from video, which can provide data SUDDOrt for the studv of microscopic traffic system. |
