Abstract :
Radiometric compensation has made it possible for a projector to display on ordinary surface with colors and textures. For previous methods, itpsilas necessary to calibrate both the projector and camera at first. The calibration can be time-consuming and needs to be redone once the system settings change. We present a method that simplifies the calibration process. As a result, the system is more practicable for ad-hoc setups.
