Abstract

For more than three decades, measurement of distance has been carried out during routine and normal surveying tasks. Today, thanks to advancements in computer technology, automatic collection and processing of large volumes of field data and laser fields have become possible. Short-distance laser 3D mapping systems that are derived from these advancements, have the ability to provide accurate computer models with great details from a wide range of objects including construction works, industrial complexes, works of art and architecture within very short periods of time. The authors of this paper discuss the operation and possibilities of systems for preparation of short-distance laser 3D mapping. They also compare the supporters and critics of this technique with the supporters and critics of photogrammetric system.
