Title:
INFORMATION PROCESSING APPARATUS, METHOD OF DERIVING REFLECTION CHARACTERISTICS, PROGRAM, AND REFLECTION CHARACTERISTIC PROFILE
Document Type and Number:
WIPO Patent Application WO/2017/199691
Kind Code:
A1
Abstract:
To provide a technique of obtaining the reflection characteristics of an object, which can reproduce the appearance of the object more correctly, an information processing apparatus (101) obtains a plurality of measurement values by receiving, from each of a plurality of directions, reflected light from an object illuminated by light from a given direction, and derives, based on the plurality of measurement values, a characteristic of specular reflection light as a reflected light component in a specular reflection direction corresponding to the given direction with respect to a surface of the object, a characteristic of internal diffuse reflection light as a reflected light component after scattering and absorption in the object, and a characteristic of surface diffuse reflection light as a reflected light component which has been diffused on the surface of the object.
