Abstract

This paper presents a fast continuous geometric calibration method for projector-camera system under ambient light. Our method estimates an appropriate exposure time to prevent features in captured image from degradation and adopts ORB descriptor to match features pairs in real-time. The adaptive exposure method has been verified with different exposure values and proved to be effective. We also implement our real-time continuous calibration method on Dual-projection display. The calibration process can be accomplished smoothly within 5 frames.
