    Abstract:

    We propose an auto-calibration method for photometric stereo. Our method exploits constraints placed on light sources to recover their positions and the surface normals of an object up to a scaling and planar rotation ambiguity. The ambiguity is resolved with multi-view consistency constraints leading to a Euclidean reconstruction of the ...More
