| 摘 要： | 本文研究和探讨如何由单幅图象的阴影进行三维信息的提取,以恢复物体表面的形状。通过引入立体投影的概念,并附加适当的约束条件,利用边缘信息提供的边界条件,推导出由阴影计算物体表面形状的迭代算法,最后完成立体显示。 |

| Abstract: | Method tor obtaining 3-D information from a single image is discussed in this paper uhich can recover the object's surfacl shape. By introducing the concept of stereographic projection, an iterative method for computing shape from shading using the suitable smoothness conslraints and the boundary condition is proposed. Finauy, the reconstruction surface is given out on television monitor on 3-D view image. |
