Abstract

A method and system to capture geometry of a three dimensional target while disambiguating multiple projected target elements. The system projects at least three light pattern elements toward a target at a diverse spacing relative to each other. The system captures at least one image of the target while illuminated by at least one of the pattern elements. The pattern elements are moved relative to the target. The system disambiguates one pattern element from any other contained within an image of the target, at least in part based on the diverse spacing. The system measures triangulation locations of points on a three-dimensional surface of the target.
