Evaluation of close range photogrammetric support for Pavescan

Pavescan is a low cost mobile system for road modelling survey. Because of the absence of navigation sensors it has several practical drawbacks compared to most of the other mobile mapping systems, but those sensors are very expensive and do not fulfil most of the accuracy requirements. Pavescan will be more attractive if some of the practical...

Vibration Measurement of a Model Wind Turbine using High Speed Photogrammetry

To meet the growing demand for sustainable energy, existing wind turbines have to be made more powerful and efficient. One of the research topics to achieve this, is the aero-elastic stability limit of the blades. This can be analyzed by the vibrations that occur on the blades during normal operational conditions. In this study high speed...

Evaluation of a laser Land-based Mobile Mapping System for measuring sandy coast morphology

The coastal area is an important territory for many reasons, e.g. as a recreational area, natural parks and reservoirs, protection against sea flood and storms. The last usage is especially crucial in the Netherlands, because the most densely populated areas are located just behind the coastal defense and are partly below the mean sea level....

Automating quantity surveying in road construction using UAV Videogrammetry

Due to changing contract forms in road construction, contractors feel the need for accurate and fast quantity measurement methods. UAV Photogrammetry is a potential answer for contractors. Photogrammetric measurement processing should be automated in order to reach its full potential in speed and obtainability. Automatic extraction of reliable...

Aerostat Photogrammetry for Large Scale Hydrological Modeling with Special Focus on Energy Balance Terms

Knowledge of temperature distributions on streams and lakes is considered to be a valuable source of information for a wide range of disciplines such as ecologists, hydrologists and geochemists, as it can provide insights into the dynamics of these water bodies (Westhoff, 2006). Modeling of surface water temperature on the other hand is a...
