摘要

In this research, the authors have developed a compact and fast measurement system for three-dimensional (3D) shape, normal vector, and bidirectional reflectance distribution function (BRDF) of a 3D object, e.g., a human face. Since the proposed system uses linear light sources and a luminous intensity distribution of these light sources, the BRDF can be measured for a short time and without large measurement space. The proposed system is evaluated by two methods whereby the authors confirmed its accuracy: by measuring sample known objects and by comparing actual and reproduced images.
