遮挡边缘和局部阴影是表面形状估计的重要线索。本文利用不同视点下的遮挡边缘序列，获取它们所对应的表面点的三维几何关系。并结合局部阴影分析，对物体表面的非暴露区域进行深度（高度）计算。最终通过插值，获得表面三维模型，实现真实目标建模。

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.
