Consistent Illumination within Optical See-Through Augmented Environments

Abstract: We present techniques which create a consistent illumination between real and virtual objects inside an application specific optical see-through display: the virtual showcase. We use projectors and cameras to capture reflectance information from diffuse real objects and to illuminate them under new synthetic lighting conditions. Matching direct and indirect lighting effects, such as shading, shadows, reflections and color bleeding can be approximated at interactive rates in such a controlled mixed environment.
