Projector Defocus Correction

Abstract

In this chapter, we propose a method that displays an in-focus image onto off-axis surface based on a single projector-camera image pair matching algorithm. Making a pair of projector and camera, the proposed method first estimates defocus parameters on the off-axis surface. Then, generate a sharpened image that contains enhanced edge according to the estimated defocus parameters. Finally, the sharpened image is projected to the surface to cancel the defocus effect. The proposed method assumes that display surface is planar and Lambertian.
