Best Practices When Using Multi-Rotor Consumer UAVs for Photogrammetric Mapping: Limitations and Possible Solutions
Photogrammetry has seen great technological advancements since its inception almost 150 years ago. Today digital cameras are being mounted to unmanned aerial vehicles (UAVs) and used for aerial surveying and photogrammetry. ... -
A Combined Method for Vegetation Classification Based on Visible Bands from UAV Images: A Case Study for Invasive Wild Parsnip Plants
Wild parsnip is an invasive plant that has serious health risks to humans due to the toxin in its sap. Monitoring its presence and spread has been challenging for conservation authorities due to its small size and irregular ... -
Development and Evaluation of Unmanned Aerial Vehicle (UAV) Magnetometry Systems
(2016-11-02)In this thesis, the procedure of conducting magnetic surveys from a UAV platform is investigated. In the process of evaluating UAVs for such surveys, magnetic sensors capable of operating on a UAV platform were tested using ... -
Impact of 3-D Attitude Variations of a UAV Magnetometry System on Magnetic Data Quality
(Wiley, 2018-12-04)Optically pumped vapour magnetometers have an orientation dependency in measuring the scalar component of the ambient magnetic field which leads to challenges for integration with mobile platforms. Quantifying the 3-D ... -
Surveillance Gone Too Far? Individual Reactions to the Use of Drones in Urban Areas.
Unmanned Aerial Vehicles (UAVs), popularly referred to as ‘drones’, have increased in popularity over the past two decades. Various concerns have been raised about their implementation, primarily focusing on their surveillance ... -
Towards Mapping of Rock Walls Using a UAV-Mounted 2D Laser Scanner in GPS Denied Environments
(2016-10-06)In geotechnical engineering, the stability of rock excavations and walls is estimated by using tools that include a map of the orientations of exposed rock faces. However, measuring these orientations by using conventional ...
