Photometric stereo - Wikipedia

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.
