N1 - Funding Information: This work was funded by Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) HE1822/37-1 for Institute of Photogrammetry and GeoInformation and NE1453/5-1 for Geodetic Institute Hannover. The platform was developed in cooperation with Prof. Dr. Stephan Schulz and his team at Dept. of Mechanical Engineering and Production Management, HAW Hamburg.

N2 - Multi-view camera systems are used more and more frequently for applications in close-range photogrammetry, engineering geodesy and autonomous navigation, since they can cover a large portion of the environment and are considerably cheaper than alternative sensors such as laser scanners. In many cases, the cameras do not have overlapping fields of view. In this paper, we report on the development of such a system mounted on a rigid aluminium platform, and focus on its geometric system calibration. We present an approach for estimating the exterior orientation of such a multi-camera system based on bundle adjustment. We use a static environment with ground control points, which are related to the platform via a laser tracker. In the experimental part, the precision and partly accuracy that can be achieved in different scenarios is investigated. While we show that the accuracy potential of the platform is very high, the mounting calibration parameters are not necessarily precise enough to be used as constant values after calibration. However, this disadvantage can be mitigated by using those parameters as observations and refining them on-the-job
