The occluding edge and local shading information are the important cues for surface shape estimation. In this paper

we use the occluding edge sequence at different view points to acquire the 3-D geometry relations of the responding points on the object surface. And then integrating the local shading information analysis

we can compute the depth of the unexposed areas on the surface. Eventually

by interpolating we can acquire the 3-D model of the surface and implementthe objects modeling.
