Abstract
Existing radiometric compensation methods are based on the assumption that the projection surface (screen) is Lambertian, i.e. there exists no specular reflection. Thus the methods cannot be applied to non-Lambertian surfaces which are ubiquitous in our everyday environment. In this paper, we try to faithfully display an image onto non-Lambertian surfaces using multiple overlapping projectors and cameras. The projectors which are separated at a distance would hardly produce specular reflection at the same time at the same point of the projection surface. Therefore, we can reasonably assume that there is at least one diffuse projector which does not generate specular reflection in a region of projection surface at a camera viewpoint. From the perspective of the diffuse projector-camera pair, the region of projection surface looks like Lambertian and the existing radiometric compensation methods could be employed for compensating the radiometric distortion of the region. Experimental results are given to show the validity of our method.
