Photometric stereo教學
WebJan 3, 1992 · Photometric stereo is used in computer-based image understanding. It can be applied in two ways. First, it is a general technique for determining surface orientation at each image point. WebPhotometric stereo is a technique in computer vision for estimating the surface normals of objects by observing that object under different lighting conditions. It is based on the fact that the amount of light reflected by a surface is dependent on the orientation of the surface in relation to the light source and the observer. By measuring the amount of light reflected …
