Abstract:
We present a novel acquisition device to capture high resolution 4D re- flectance fields of real scenes. The device consists of a concave hemispher- ical surface coated with a rough specular paint and a digital video projector with a fish-eye lens positioned near the center of the hemisphere. The scene is placed near the projector, also near the center, and photographed from a fixed vantage point. The projector projects a high-resolution image of incident illu- mination which is reflected by the rough hemispherical surface to become the illumination on the scene. We demonstrate the utility of this device by cap- turing a high resolution hemispherical reflectance field of a specular object which would be difficult to capture using previous acquisition techniques.
