    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    Författare :Yuriy Reshetyuk; KTH.; [2006]
    Nyckelord :terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

    Sammanfattning : 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. LÄS MER

  3. 3. Estimation of canopy structure and individual trees from laser scanning data

    Detta är en avhandling från ; Institutionen för skoglig resurshushållning, Sveriges lantbruksuniversitet

    Författare :Eva Lindberg; Sveriges lantbruksuniversitet.; [2012]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the last fifteen years, laser scanning has emerged as a data source for forest inventory. Airborne laser scanning (ALS) provides 3D data, which may be used in an automated analysis chain to estimate vegetation properties for large areas. LÄS MER
