Paper Abstract

In this paper, a novel radiometric compensation algorithm based on Lambertian reflection model is proposed to neutralize the visual perception of colors and textures which are intrinsic to the projection display surface. The algorithm uses a calibration method of advanced coded structure light to determine the geometric mapping between corresponding points in the projector-camera system. Concrete analysis of the dynamic range of projectors is applied to obtain the intensity limits of the input image. Consequently, the Lambertian reflection model is constructed for each point to compute the radiometric compensation function between displayed images and camera captured images. Experimental results show that this algorithm can effectively correct color inaccuracy of projection on arbitrary textured surfaces, and observers almost hard to notice visible artifacts of projected images.
