Paper Abstract

One method for measuring the shape of a three-dimensional (3-D) object is to project light rays onto its surface, image the resulting scene with a camera, and triangulate the illuminated object points. The locations of the projected rays, and their correspondences with the camera image of their incidences with the object surface, must be known for the triangulation procedure. This paper describes how the pattern illumination technique can be refined for range mapping without the usual correspondence information, and in fact without knowledge of the projected ray locations themselves. This is done by displacing the camera and/or projector between image captures.
