Abstract
A three-dimensional coordinate measuring system which includes first and second towers, first and second viewing devices mounted on the first and second towers, respectively, and a pair of targets mounted on each of the first and second towers a known distance apart. A tilt sensor is mounted on each of the first and second towers to measure the angle of each of the first and second towers with vertical and a host computer is coupled to each of the viewing devices and is programmed to perform photogrammetric algorithms so as to compute the coordinates of unknown points.
