Where Is the Ground? Quality Measures for the Planar Digital Terrain Model in Terrestrial Laser Scanning
In the analysis of terrestrial laser scanning (TLS) data the digital terrain model (DTM) is one of important elements. To evaluate the DTM or to find the DTM by way of optimization it is necessary to formulate the measure of DTM quality. Three parameterized measures are proposed and tested against a comparative model for a series of TLS data. The measure equal to the number of points inside a l...
متن کاملOblique Helicopter-based Laser Scanning for Digital Terrain Modelling and Visualisation of Geological Outcrops
Terrestrial laser scanning is becoming increasingly popular for modelling geological outcrops, because of the high resolution, accuracy and ease of dataset integration. Despite these significant advantages, limitations with the technique remain when the spatial extent of the study area is large, as most current systems have a maximum range of less than one kilometre. This becomes a major proble...
متن کاملUsing Terrestrial Laser Scanning and Digital Images for 3D Modelling of the Erechtheion, Acropolis of Athens
This work is part of the project “Development of Geographic Information Systems at the Acropolis of Athens“. Within this project one of the aims was the generation of a textured, high-resolution, accurate 3D model of the Erechtheion and a realistic computer animation. For most parts, we used a medium-range time-of-flight (TOF) phase-based laser scanner with minimum lateral data spacing of 1 mm ...

متن کاملFusion of Terrestrial Laser Scanning and Digital Photogrammetry
Terrestrial laser scanners are introduced in the market in various construction forms, dispose of various measuring principles and are used in the most different areas of application. Combining the information of the gray-scaled point cloud with the geometry informations of rgb-colored images results in improved possibilities of object interpretation and measurement. The coalescence of both dat...
