Abstract :
An optimal 3D viewing method with tilted camera configurations is presented for advanced telemanipulations. As compared to the parallel camera configurations, which are special cases of tilted camera configurations, tilted camera configurations have more horizontal accuracy but with less vertical accuracy. However, this poor vertical accuracy of tilted camera configurations can be compensated by using different horizontal and vertical scaling factors. Besides, better depth resolution and near stereoscopic viewing can be achieved with tilted camera configurations. The method determines in real-time the optimal parameter values associated with stereo imaging and image projection on a video screen. These values implement the optimal stereo viewing adaptive to the focus of attention of the viewer. The simulation results of a tilted camera configuration are given, and they are compared to the results obtained from a parallel camera configuration
