Linear perspective shape-from-shading method with two images
Journal of Systems Engineering and Electronics(2015)
摘要
Shape-from-shading (SFS) is one of the important approaches of 3-D surface reconstruction in computer vision. Since reflectance map equation in SFS is a nonlinear partial differential equation (PDE) with two unknown variables, SFS with one image is ill-posed in mathematical sense. A linear perspective SFS method with two images is proposed to deal with the problem. We assume that two images with d...
