Real-time appearance modification of textured object using superimposed projection

As commercial projectors become cheaper and smaller, appearance modification technique which employs projection display technologies now impact more areas including culture heritage, product design and architectural relighting. In this paper, we introduced a new method that use superimposed projection to modify the appearance of a non-planar textured object in real-time. Both the geometric and the radiometric models of the system are recovered during the calibration. After the recovery of system parameters, desired images are pre-warped in real-time. The target textured object presents new appearances dynamically when lighted with the custom designed illumination. Experimental results show that our system performs well in both rendering speed and keeping the contrast.
