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 is a technique to estimate depth and surface orientation from images of the same view taken from different directions. Theoretically, only three directions are … WebIn this project, you will be implementing a Photometric Stereo algorithm.
