WebPhotometric stereo is a form of structured lighting that increases the information available from surface reflectance variations. Basically, instead of taking a single monocular image of a scene illuminated from a single source, several images are taken, from the same vantage point, with the scene illuminated in turn by separate light sources. WebPhotometric stereo description. Photometric stereo is a method of estimating surface geometry by using a ﬁxed-position camera and multiple light sources. It was proposed by Robert J Woodham in 1980 as an alternative to other stereo techniques, that needed two images of the same object, viewed from different directions, to determine its ...

Photometric 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 … See more The classical photometric stereo problem concerns itself only with Lambertian surfaces, with perfectly diffuse reflection.
