Outline of Final Research Achievements |
We aim to simultaneously estimate object's shape and BRDF by reconstructing light field of incident and reflected rays from scattered light in participating media. As well as X-ray computed tomography, we observed the scattered light by moving a camera around the subject. However, different from X-ray CT, it is required to care about the anisotropy of the scattering in tomography. Thus, we have developed methods to measure a phase function of the scattering media, appropriate optical density where single scattering is dominant, and reconstruct the light field from the observation where the scattering is anisotropy to simultaneously estimate the shape and BRDF of the subject.
