| Abstract;If a pattern is projected to a non-planer screen, the desired view cannot be correctly observed due to the influence of inter-reflections. This paper proposes a simple but effective technique for photometric compensation in consideration of inter-reflections on a concave surface. The compensation is accomplished by canceling inter-reflections estimated by the radiosity method. The significant advantage of the proposed method is that any iterative calculations are not necessary for the photometric compensation because it analytically solves the inverse problem of inter-reflections. Experimental results show that the influence of inter-reflections is effectively reduced. (author abst.) |
