In recent years, volumetric capture technology has been actively developed and put to practical use for the purpose of content creation in xR and rich video expression. In order to achieve a high realism in the rendering of volumetric video and to composite it in a natural way consistent with real space during the AR experience, it is necessary to add material property information to the volumetric video that allows the lighting conditions to be changed. In this report, we propose a material properties measurement method that can be applied to volumetric capture. The proposed method is characterized by the use of polarized light, color three-phase photometric stereo, and a multi-dot DOE laser pattern projector to obtain reflection coefficients, normal information, and sub-surface scattering parameters from a few frames of captured video. This report shows experimental results of the proposed method and demonstrates the effectiveness of the principle. |
