Acquiring Range Images of Objects with Non-Uniform Reflectance Using High Dynamic Scale Radiance Maps

Abstract

We present a novel approach to acquisition of range images of objects with non-uniform reflectance using a structured light sensor. The main idea is to systematically vary the illumination intensity of the light projector and to form high dynamic scale radiance maps. The range images are then formed from these radiance maps. We tested the method on the objects which had surfaces of very different reflectance properties. We demonstrate that range images obtained from high dynamic scale radiance maps are of much better quality than those obtained directly from the original images of a limited dynamic scale.
