Vehicle localization based on geometric configurations of landmarks

11/09/2009

Jan-Henrik Haunert, since 1/09/09 research associate at the chair of Computer Science I, presents a new method for vehicle positioning at the conference ACM SIGSPATIAL 2009.

Autonomous vehicles need accurate and reliable positioning. The positioning system GPS cannot satisfy these requirements alone since it often fails due to shadowing effects at trees or houses. Therefore, other sensors such as laser scanners and cameras are needed in addition to GPS receivers. Objects like traffic signs or trees can be extracted from the measurements of such sensors. Matching these objects - so-called landmarks - with objects on a map can solve the positioning problem.

Jan-Henrik Haunert developed methods for this matching problem at the Institute of Cartography and Geoinformatics of the Universität Hannover. His approach is to analyze the geometric configuration of the landmarks. At the University of Würzburg he's continuing this line of research. At the ACM SIGSPATIAL GIS 2009, he presents results that he achieved with Claus Brenner. The slides of his talk are available here.
