WebPhotometric stereo: 3D machine vision: Special tools e.g. fast image segmentation, fast line segment detection: Deep Learning Add-on feature detection, anomaly detection, object … 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.
