Abstract

See full text

A coordinate measuring device is provided having a light source that emits a beam of light. A distance meter measures a distance to a target. A first locator camera assembly includes a first camera and first lights. A second locator camera assembly includes a second camera and second lights. The processor matches retroreflectors in a first image of the first camera and a second image of the second camera based on a shape-and-context matching of retroreflector spots in the first and second image and on an area-context-matching of background objects in the first and second image. The retroreflector spots in the first image produced by illumination of the retroreflectors by the first lights, the retroreflector spots in the second image produced by illumination of the retroreflectors by the second lights. The processor provides a third image that includes both the background objects and markers indicating the matched retroreflectors.
