TERRESTRIAL LASER SCANNING – POINT CLOUD IN BUILDING CONSTRUCTION

3D laser scanner refers to terrestrial (stationary), mobile (vehicle-mounted), or aerial (aircraftmounted) scanning devices. Terrestrial Laser Scanning (TLS) is increasingly used in the Architectural, Engineering, Construction and Facilities Management industry (AEC&FM) due to the significant performance improvements that it can support. TLS is a modern technology that is revolutionizing surveying works. One of the key advantages of laser scanning is the ability to quickly obtain large amounts of data in a short time. The result of laser scanning is a point cloud. Point cloud is essentially a three-dimensional (3D) imaging system which is used for the digital representation of the existing respectively of the real state of building objects. Point cloud has in building construction a very wide application. The aim of this article is explain what is TLS, what is a point cloud and describe how to use him in different areas of building construction.
