    摘要： A method for locking onto and tracking a selected retroreflector target with a laser tracker includes steps of: actuating by the operator the handheld appliance and sending a wireless signal; responding to the wireless message by repetitively carrying out steps in the following loop and exiting the loop when an exit condition is met: reflecting part of the cone of light by the at least one retroreflector target and capturing an array image on the photosensitive array; determining which retroreflector target meets the retroreflector target criterion; determining whether the position detector is receiving the reflected beam; establishing that the exit condition is met when the position detector receives the reflected beam and the reflected beam comes from the selected retroreflector target; and steering the first light beam toward the selected retroreflector target.

Providing a contact element rigidly fixed with respect to the body. A device is provided having a frame of reference and a light source, the device configured to measure a distance and two angles from the device to the retroreflector reference point.

    摘要： 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.
