Large structures are measured many ways. Meters providing high accuracy require jigs such as special targets. Targetless measurement usually provides low accuracy. Measurement using targets requires time at the work site for setting targets, which may require elevated spot work that is not always safe. We developed measurement incorporating laser theodolite and a CCD camera.
