In this paper, we propose a method to resolve occlusion problem for tabletop AR based city plan system using stereo vision and accurate boundary depth recovery of foreground objects. Firstly, we design a color and brightness based foreground subtraction approach to avoid the negative effect of shadows. Then, we get the depth information for represent correct occlusion between virtual and real objects based on contour matching and depth interpolation. Some experiments have been carried out to demonstrate the validity of the proposed approach.
