|Abstract:||We present a geometry-based method for long term positioning and mapping, with ability to correct positioning errors and recognize geometry of previously visited regions. The method is implemented in a prototype system for simultaneous localization and mapping (SLAM) based on a time-of-flight (TOF) camera and an inertial measurement unit (IMU). In the system, landmark-based navigation is combined with the presented method for geometry-based loop closure. In this paper we show early results from the system in indoor environments. These results shows considerable improvements compared to not using loop closure, when areas are revisited within a short time.|
