Abstract(in English) In this paper, we address the problem to recovering 3D shape of an unfolded book surface from the shading information in a scanner image by using eigen space method. In this method, some shading and shape profile data are acquired previously, and preserved in eigen space to reduce the data size. The book surface can be restored from a shading profile by assuming linear interpolation in the shape and shading eigen space locally. To reduce the freedom of profile data, they are normalized to the shift invariant profile by FFT. We demonstrate the shape recovering by model and real book surface, and the geometric and photometric distortion can be removed in the scanner image.
