Geometry of a General Three-Camera Headmounted System.

摘要

A three-dimensional scene, such as a proposed building, an imaginary landscape, or an organic molecule, is selected, described in abstract terms, and stored in a computer's memory. A person wears a special helmet, in a laboratory whose inner wall is dotted with 'landmark' LEDs. The helmet is equipped with a location system and a projection system. As the wearer moves in the laboratory, changing the helmet's position (and orientation) in a natural manner, the location system allows the computer to keep track of the helmet's position, and the computer sends appropriate information to the projection system, to display the view of the selected scene (suitably scaled) that would be seen by the wearer during this motion.
