Abstract :
In this paper, we present a method for photometric self- calibration of a projector-camera system. In addition to the input transfer functions (commonly called gamma functions), we also reconstruct the spatial intensity fall-off from the center to fringe (commonly called the vignetting effect) for both the projector and camera. Projector-camera systems are becoming more popular in a large number of applications like scene capture, 3D reconstruction, and calibrating multi-projector displays. Our method enables the use of photometrically uncalibrated projectors and cameras in all such applications.
