In this paper, we propose a new 3D modeling method called DSFS.This method combines two methods , shape from silhouette and shape from shading, to compensate for their faults while retaining their advantages .The DSFS method models the object accurately and quickly, and, at the same time, it solves the concave surface modeling problem what was difficult for conventional shape from silhouette methods.Compared to other shape from shading methods, the iterative stage of DSFS is more stable and more accurate, without sensitivity to the experimental environment.The effectiveness of DSFS has been confirmed by the experimental results though computer simulation.
