Terrestrial Laser Scanning – Civil Engineering Applications

Three dimensional terrestrial laser scanning has already proved its potential in several application fields, such as topography, archaeology, mining and cultural heritage protection. Beside these areas a new demand emerged: accurate point cloud acquisition and post-processed results in engineering survey. This technology could broaden the field of engineering survey, although the limited accuracy has to be carefully considered. In order to confirm the accuracy claimed by the manufacturer, the Department of Photogrammetry and Geoinformatics carried out two complex laboratory measurements, where not only the main accuracy values were examined but the effect of different materials, colours and the incident angle.
