Title: Camera theodolite system

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