  • Classifying the Degree of Bark Beetle-Induced Damage on Fir (Abies mariesii) Forests, from UAV-Acquired RGB Images 
    Leidemer, Tobias; Gonroudobou, Orou Berme Herve; Nguyen, Ha Trang; Ferracini, Chiara; Burkhard, Benjamin; Diez, Yago; Lopez Caceres, Maximo Larry (Basel : MDPI, 2022)
    Bark beetle outbreaks are responsible for the loss of large areas of forests and in recent years they appear to be increasing in frequency and magnitude as a result of climate change. The aim of this study is to develop a ...
  • Integrated estimation of UAV image orientation with a generalised building model 
    Unger, Jakob (Hannover : Leibniz Universität Hannover, 2020)
    The estimation of position and attitude of a camera, addressed as image orientation in photogrammetry, is an important task to obtain information on where a platform is located in the world or relative to objects. Unmanned ...
  • Mounting calibration of a multi-view camera system on a uav platform 
    Mohammadi, M.; Khami, A.; Rottensteiner, F.; Neumann, I.; Heipke, C. (Katlenburg-Lindau : Copernicus, 2021)
    Multi-view camera systems are used more and more frequently for applications in close-range photogrammetry, engineering geodesy and autonomous navigation, since they can cover a large portion of the environment and are ...
  • A new approach for an incremental orientation of micro-UAV image sequences 
    Reich, Martin; Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2014)
    Civil applications for small size unmanned aerial vehicles (UAV) have become quite important in recent years and so have accurate orientation and navigation of these devices in unknown terrain. In this work we focus on ...
  • On-line compatible orientation of a micro-uav based on image triplets 
    Reich, Martin; Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2013)
    In this paper we present a robust orientation approach for an imaging sensor flown on a micro-UAV based on image triplets. Our aim is to have the orientation available online, i.e. during image acquisition. The resulting ...
  • Proceedings of the 11th European Workshop on Aircraft Design Education 
    European Workshop on Aircraft Design Education (EWADE) (Linköping : EWADE, 2013)
    These are the Proceedings of the 11th European Workshop on Aircraft Design Education (in short: EWADE 2013). The workshop took place from 17. to 19.09.2013 in Linköping, Sweden. EWADE 2013 was for the first time integrated ...
  • Remote Sensing for Property Valuation: A Data Source Comparison in Support of Fair Land Taxation in Rwanda 
    Koeva, Mila; Gasuku, Oscar; Lengoiboni, Monica; Asiama, Kwabena; Bennett, Rohan Mark; Potel, Jossam; Zevenbergen, Jaap (Basel : MDPI, 2021)
    Remotely sensed data is increasingly applied across many domains, including fit-for-purpose land administration (FFPLA), where the focus is on fast, affordable, and accurate property information collection. Property ...
  • Review of remote sensing for land administration: Origins, debates, and selected cases 
    Bennett, Rohan Marc; Koeva, Mila; Asiama, Kwebana (Basel : MDPI AG, 2021)
    Conventionally, land administration—incorporating cadastres and land registration—uses ground-based survey methods. This approach can be traced over millennia. The application of photogrammetry and remote sensing is ...
  • Störfestigkeitsuntersuchung eines Unmanned Aerial Vehicles mit Hilfe der stochastischen Beschreibung der Subsysteme 
    Brech, Henrik; Garbe, Heyno (Aachen : Apprimus, 2020)
    In den letzten Jahren hat die Anzahl an Unmanned Aerial Vehicles (UAV) aufgrund der starken Kommerzialisierung zugenommen. Neben der Nutzung zu Freizeitzwecken können diese Flugobjekte jedoch auch zur Gefährdung für kritische ...
  • Thermal IR imaging: Image quality and orthophoto generation 
    Sledz, A.; Unger, J.; Heipke, C. (Göttingen : Copernicus GmbH, 2018)
    This paper deals with two aspects of photogrammetric processing of thermal images: image quality and 3D reconstruction quality. The first aspect of the paper relates to the influence of day light on Thermal InfraRed (TIR) ...
  • UAV-based photogrammetry: Monitoring of a building zone 
    Unger, Jakob; Reich, Martin; Heipke, Christian (Göttingen : Copernicus GmbH, 2014)
    The use of small-size unmanned aerial vehicles (UAV) for civil applications in many different fields such as archaeology, disaster monitoring, aerial surveying or mapping has significantly increased in recent years. The ...
