The 3D Data Acquisition research group led by Prof Alain De Wulf focuses on the acquisition techniques of three-dimensional spatial objects that, traditionally, make up the field of surveying and geomatics.

Research is carried out into improving the accuracy, quality and efficiency of measurement methodologies and combined or even integrated techniques using topographic, bathymetric and photogrammetric instruments: levelling devices, robotic total stations, digital cameras for terrestrial photogrammetry, differential GNSS receivers, laser scanners, singlebeam, multibeam, mobile mapping systems, satellite images, aerial photos, drone images, etc.

There are important ongoing projects on the one hand concerning the geomorphological monitoring of beaches and on the other concerning the modelling of a new equipotential surface at mean sea level for the for the Belgian Continental Shelf (BCP), including the development of a new hydrographic computer model for a more accurate tide height prediction for the BCP.

Prof. A. De Wulf's vision is that there are two major different needs within the 3D group: a scientific staff need on the one hand, and an instrument need on the other. An urgent need is an own full-time assistant who can help support the 3D department, both logistically (in terms of services to other departments) and purely scientifically. The basic financing will provide a useful impetus for this and will be supplemented either by collaboration with a colleague or by Prof. A. De Wulf's already available cash resources. 3D acquisition calls for constantly evolving measurement tools, mainly laser scanners, satellite positioning receivers and photomodelling software. This requires continuous investment for which core funding is extremely useful.
