Abstract
Disclosed herein are three-dimensional projection systems and related methods employing two electronically controlled projectors and a retro-reflective screen. The retro-reflective screen produces a known non-linear light reflection pattern when images are projected thereon. Image computational means are used to calculating flat image information for each projector based upon inputted stereopair images and information regarding the projectors and screen. In preferred embodiments of the present invention, the projection system uses an image computational device that employs a neural network feedback calculation to calculate the appropriate flat image information and appropriate images to be projected on the screen by the projectors at any given time. More than two projectors can be employed to produce multiple aspect views, to support multiple viewers, and the like. In another embodiment, the projection system includes a digital camera that provides feedback data to the image computational device.
