Integrated georeferencing of airborne multisensor systems at the cm-level

Research funding project
The project ¿Combined sensor autonomous and ground supported georeferencing for airborne multisensorsystems for cm-accuracy level¿ deals with enhancements in georeferencing of airborne sensor data to get a more accurate, more efficient and more economical solution. In recent years airborne laserscanning has become a frequently used approach to receive geometrical information about the earth surface. The project partner Bewag Geoservice GmbH commercially provides such laserscanner point clouds. Georeferencing, thus the transformation of the laserscanner point cloud into a specified coordinate frame (e.g. national surveying system), is currently realized by means of direct determination of the parameters of the flight trajectory (position, orientation in space) by GNSS/IMU-Integration (GNSS = Global Navigation Satellite Systems, IMU = Inertial Measurement Unit). In order that the laserscanner accuracy level ( 2cm) can not be reached on the earth surface. Within this project an accuracy and reliability enhancement shall be gained on the one hand by improvements during the GNSS processing and IMU calibration. On the other hand in collaboration with the Institute of Photogrammetry and Remote Sensing of TU Vienna by using the integrated georeferencing approach, thus the combination of GNSS/IMU integration and strip adjustment.
