Efficiently Measuring with Prescribed Quality in Huge LMMS Point Cloud Data
Metric applications of Laser Mobile Mapping typically require results of a prescribed quality. For example, the height of a road viaduct or the position of railroad furniture should be reported within certain error bounds. Relatively loose error bounds can be met by only processing a fraction of the points that would be needed to meet very strict error bounds, but a systematic analysis of i) which fraction of a point cloud is needed to meet a given bound, and ii) how to efficiently identify this fraction, is still largely lacking. The presentation will illustrate this problem on several LMMS examples, and will give first insight in theory that could solve this issue.
Roderik Lindenbergh studied Mathematics at the University of Amsterdam, the Netherlands. He obtained a Ph.D. in pure Mathematics from the University of Utrecht, the Netherlands, for his work on limits of Voronoi diagrams. After his Ph.D., he joined the current Department of Geoscience and Remote Sensing of Delft University of Technology where he is currently employed as an assistant professor. His research interests are focused on those applications of notably laser range data where the signal to noise ratio is critical. Roderik is Co-Chair of the ISPRS working group V/3 on terrestrial 3D imaging and sensors and is the TU Delft project leader of the IQmulus FP7 project developing a high-volume fusion and analysis platform for geospatial point clouds, coverages and volumetric data sets.
