AbstractIn this paper, we propose a hand-held mobile projection system that can freely project keystone free content on a general flat surface without any markings. Such a projection system can give the user great freedom of control of the display such as viewing angle and distance without suffering from distortion. We attach a camera to the projector to form a stereo pair. The correction of the display content is then achieved by rectifying the projection region of interest into a rectangular region and pre-warping the display content. Experimental results show that our system can continuously project distortion free content in real time with reasonable precision.
