註釋For over thirty years researchers have been trying to solve the Shape from Shading problem of determining 3D shape from a single image with a single light source. This paper shows that this problem can never be solved perfectly due to challenges of light orientation, camera type, ambiguity, multiple materials, and specular highlights. However, we can get accurate results on small, simple shapes where we can make assumptions to remove these challenges. This paper shows each of these challenges can be overcome through the use of other techniques such as pattern matching and stereopsis. The paper will then present a new hybrid method of Shape from Shading that can be used to autonomously capture 3D information from 2D images of single objects with multiple peaks and multiple materials with specular components.
