Multi-View Azimuth Stereo via Tangent Space Consistency

Recovered normal maps Recovered shape Azimuth geometry normal 𝑧 (camera optical axis) Figure 1 . 3D reconstruction from calibrated multi-view azimuth maps (3 out of 31 are shown). An azimuth angle indicates the surface normal's orientation in the image plane, and an azimuth map records the azimuth angles across the entire surface. We show that azimuth maps can be effectively used for shape and normal recovery. Color images are for reference only and are not used in shape optimization.
