The research introduces LUCES, the first real-world dataset specifically designed for near-field point light source photometric stereo, featuring 14 diverse objects with 52 images each, calibrated light parameters, and high-accuracy ground truth 3D models. This dataset enables standardized evaluation and development of algorithms capable of handling complex close-range illumination effects.

Key insights

  • Far-field photometric stereo methods consistently failed under near-field conditions, empirically validating the necessity of algorithms specifically designed for close-range illumination.
  • Deep learning-based photometric stereo methods generally surpassed classical optimization approaches on the LUCES dataset, indicating their effectiveness in learning complex non-linear shading relationships.
  • Material specularity proved less detrimental to the performance of CNN-based methods on convex object regions, suggesting an implicit learning of complex BRDFs without explicit modeling.
