摘要: Abstract This paper describes a new method for constructing depth map from surface normals. In this recovery method, an arbitrary must be first preset point somewhere in the image, then path-independent line integrals are computed to get relative depths at every pont image. The validity of proposed is discussed and its efficiency was tested using normals obtained by shape shading algorithm. comparison previous ones given. Theoretical analysis experimental results show that our both powerful easy implement.
