摘要

We present a novel image-based BRDF (Bidirectional Reflectance Distribution Function) measurement system formaterials that have isotropic reflectance properties. Our proposed system is fast due to simple set up and automatedoperations. It also provides a wide angular coverage and noise reduction capability so that it achieves accuracy that isneeded for computer graphics applications. We test the uniformity and constancy of the light source and the reciprocityof the measurement system. We perform a photometric calibration of HDR (High Dynamic Range) camera to recover anaccurate radiance map from each HDR image. We verify our proposed system by comparing it with a previous image-based BRDF measurement system. We demonstrate the efficiency and accuracy of our proposed system by generatingphotorealistic images of the measured BRDF data that include glossy blue, green plastics, gold coated metal and goldmetallic paints.
