Résumé

We introduce a 3D reconstruction technique based on nearlight photometric stereo, where lighting calibration is achieved on-the fly from a rough geometric knowledge obtained, e.g., by structure-from-motion. From this coarse geometry, the proposed graduated optimisation setup estimates all light source parameters (position, intensity, orientation, and anisotropy factor of each source), which can then be used within a calibrated photometric stereo algorithm. A series of real-world experiments is conducted, which validates the interest of the proposed approach.
