Title:

Semi-Calibrated Photometric Stereo

Abstract:

3D shape acquisition from images is of broad interest in computer vision and relevant industry applications. This talk introduces a „photometric“ approach to high-fidelity 3D reconstruction, which enables shape recovery at the pixel-level detail. Specifically, this talk covers photometric stereo that takes as input images taken under different illumination conditions and estimates surface normal per-pixel. We introduce a new „semi-calibrated“ photometric stereo, which is in-between calibrated and uncalibrated ones, and show that requirement about the light calibration for the conventional calibrated photometric stereo can be relaxed.
