Abstract
In this paper, we propose a new scheme of one dimensional traffic flow measurement using stereo slit camera. Both slit of stereo configuration are aligned perpendicular to the motion direction. Stereo matching of two line image gives a pseudo cross section of the moving object at one time. Compilation along time axis gives pseudo three dimensional or two and a half dimensional information of the object. This make separation task very simple, and is very useful passing vehicle counting. We applied the proposed scheme to passenger vehicle image and the result seems to be very promising.
