Abstract
Shape From Darkness refers to using the shadows cast by a scene to reconstruct the structure of the scene. A collection of images associated with different light source positions is used. Previously published solutions to this problem have performed the reconstruction only for cross sections of the scene.
We propose a variant of Shape From Darkness which is capable of reconstructing the entire 3-D scene. In addition, this algorithm can be applied to a broader class of light source trajectories, including trajectories which mimic the motion of the sun during the day.
We present a formal statement of the 3-D problem and some of its characteristics, and an algorithm for recovering a surface from shadows. Experimental results are presented and discussed for both real data and synthetic data with associated ground truth.
