SVBRDF-Invariant Shape and Reflectance Estimation from a Light-Field Camera.
IEEE Transactions on Pattern Analysis and Machine Intelligence(2018)
摘要
Light-field cameras have recently emerged as a powerful tool for one-shot passive 3D shape capture. However, obtaining the shape of glossy objects like metals or plastics remains challenging, since standard Lambertian cues like photo-consistency cannot be easily applied. In this paper, we derive a spatially-varying (SV)BRDF-invariant theory for recovering 3D shape and reflectance from light-field ...
