Abstract: This article discusses a new eliminate algorithm of vehicle shadow. That is combination of the vehicle shadow characteristics and geometric model. And it is realized by OPENCV and VC 6.0 platforms. The algorithm bases on the analysis of the characteristics of vehicle shadow, and combines the shadow geometric model, transforms the coordinate of the relevant pixels, according the direction of driveway line which has been extracted, finds the critical of vehicle and shadow in the new coordinate, and then eliminates the shadow and transforms back to the original coordinate. Experimental results show that the effect of this method of vehicle shadow remove is very good.

Key words: shadow eliminate, characteristics of shadow, geometric model, coordinate transformation
