Boresight Calibration of Integrated Inertial/Camera Systems

Boresight Calibration of integrated imaging/inertial systems is a critical factor for map production, especially in the case of digital imaging sensors. The focus of this paper is therefore on boresight calibration using different approaches. Two boresight calibration approaches are presented, namely the airborne and the terrestrial approach. Traditional airborne boresight calibration has been successfully used for a few years, yet it does not satisfy some operational parameters of certain airborne digital systems. Alternatively, the terrestrial calibration approach presented here has never been used in typical digital map production. In this paper, the concepts of airborne and terrestrial boresight calibration are presented for digital multi-sensor systems. Data results and analysis are presented to emphasis the accuracy achieved using both approaches.
