METHOD AND APPARATUS FOR DETERMINING REFLECTANCE DATA OF A SUBJECT
摘要
An apparatus for obtaining reflectance data of an object includes a diffuser having a surface. The apparatus includes a mapping portion that effects a mapping between a light field at the object's surface and a light field at the diffuser surface for BRDF capture of the object. A method for obtaining reflectance data usable to determine a plurality of values of the BRDF of an object. The method includes the steps of illuminating the object. There is the step of effecting a mapping between a light field at the object's surface and a light field at a diffuser surface for BRDF capture of the object with a mapping portion. An apparatus and a method for measuring an 8D reflectance field of an object or a 3D object.
