GEOMETRIC ACCURACY ASSESSMENT OF ADS40 IMAGERY UNDER VARIOUS NETWORK CONFIGURATIONS

The ADS40 camera is a commercial example of the airborne Three-Line-Scanner (TLS). Its particular sensor geometry requires new approaches and a specialization of methods and algorithms to solve the triangulation problem. The goal of the paper is to investigate the geometric accuracy performance of an ADS40 camera under various network configurations and using different trajectory models and different sets of additional parameters for self-calibration. Investigations are performed by two independent research Groups, the Institute of Geodesy and Photogrammetry (IGP), ETH Zurich, and the Geomatics Laboratory of the University of Pavia. Identical image and point datasets are used by both parties to test different trajectory models and additional parameters for self-calibration. Th
