A method of using a portable device to select, fix and track a retroreflector with a laser tracker

摘要

A method for fixedly targeting and tracking a selected retroreflector target with a laser tracker (10) comprises the steps of: operating a portable device (410) by the operator and transmitting a wireless signal (420); Responding to the wireless message by repeatedly performing steps in the following loop and exiting the loop when an exit condition is met; Reflecting a portion of a light cone from at least one retroreflector target (26) and capturing an array image on a photosensitive array; Determining which retroreflector target (26) meets the retroreflector target criterion, the retroreflector target meeting the retroreflector target criterion being referred to as a "selected retroreflector target"; Determining whether a position detector of the laser tracker (10) receives a reflected portion of a light beam transmitted by the laser tracker (10); Determining that the exit condition is met when the position detector receives the reflected beam and the reflected beam comes from the selected retroreflector target; Directing the light beam toward the selected retroreflector target.
