  1. 1. Data assimilation of forest variables predicted from remote sensing data

    Author : Nils Lindgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Forest information for management planning is today gathered through a combination of field inventories and remote sensing, but the available flow of remote sensing data over time is not yet utilized for continuously improving predictions of forest variables. In the thesis, the utility of data assimilation, in particular the Extended Kalman filter, for forest variable prediction is investigated. READ MORE

  2. 2. Segmentation of forest patches and estimation of canopy cover using 3D information from stereo photogrammetry

    Author : Ann-Helen Granholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an affordable alternative to airborne laser scanner (ALS) data. READ MORE

  3. 3. Prediction as a Knowledge Representation Problem : A Case Study in Model Design

    Author : Patrik Haslum; Patrick Doherty; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WITAS; Unmanned irial Vehicle UAV ; helicopter; traffic surveillance; remote photogrammetry; Computer science; Datavetenskap;

    Abstract : The WITAS project aims to develop technologies to enable an Unmanned Airial Vehicle (UAV) to operate autonomously and intelligently, in applications such as traffic surveillance and remote photogrammetry. Many of the necessary control and reasoning tasks, e.g. READ MORE

  4. 4. Autonomous bridge inspection based on a generated digital model

    Author : Ali Mirzazade; Björn Täljsten; Luleå tekniska universitet; []
