2. 1. Self-calibration and direct georeferencing in terrestrial laser scanning

   Author : Yuriy Reshetyuk; Lars E. Sjöberg; Milan Horemuz; Hansjörg Kutterer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terrestrial laser scanning; self-calibration; direct georeferencing; error sources; Surveying; Lantmäteri;

   Abstract : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. READ MORE

4. 2. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

   Author : Yuriy Reshetyuk; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
   Keywords : terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

   Abstract : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. READ MORE

5. 3. Tree stem diameter estimation from terrestrial point clouds

   Author : Mona Forsman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Forest owners, governments, and environmental organizations demand forest information for planning of forest operations, estimation of value, and for environmental monitoring. This information is collected using airborne and satellite remote sensing combined with field inventory of sample plots. READ MORE
