Webb25 feb. 2012 · Shape-from-shading (also known as photoclinometry) is a method for determining the shape of a surface from its image. For a surface of constant albedo, the brightness at a point (x,y) in the image is related to the gradients (p,q) by the following expression i (x,y) = a R [p (x,y),q (x,y)] WebbIdeal shading images, as used for shape from shading (SFS), are assumed to have been captured under the general reflectance-map conditions, including orthographic projec-tion, and so they carry no depth-related blur. Shape from defocus can not therefore be based on them. On the other hand, since shading is due to surface orientation, and thus
Webb1 juli 2012 · In this paper, a simple and efficient approach is presented for the reconstruction of 3-D surfaces using the integration of shape from shading (SfS) and stereo. First, a new SfS algorithm is derived to obtain the depth-map of a 3-D surface using linear and generalized Lambertian reflectance model. WebbIn other words, one must choose boundary conditions according to the depth-complexity of the depicted surface, see e.g. Kimmel and Bruckstein (1995) for a discussion of the global SFS problem. If one instead uses a perspective camera model, the corresponding derivation from (1) yields a nonlinear partial differential equation of a more complex …
