WebPhotometric stereo itself only provides surface normals so one needs to integrate those to get a height field / depth map, which means you won't be getting absolute depth information, just a bumpy surface which has the same surface normals as your scene. It makes the most sense for uniform textureless surfaces with no self-occlusions. 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.
