Self-Calibration of Non-metric Medium Format Digital Camera in Aerial Photogrammetry with LiDAR

Abstract

Current development of CCD sensor or GPS/IMU system has offered a great contribution to progress digital aerial photogrammetry. Moreover, LiDAR system has made it possible to acquire real-time point cloud data. In these circumstances, combination of non-metric medium format digital camera and LiDAR system has been receiving more attention as make it possible to realize an efficient aerial digital photogrammetry.
However, photogrammetric data and point cloud data contain some errors. In order to reduce these errors, it is reasonable to use distance data instead of 3D data since distance data is direct value in LiDAR system. Furthermore, utilization of triplet images makes it possible to use geometric data based on trifocal tensor besides photogrammetric data and distance data.
This paper describes simultaneous adjustment for an efficient self-calibration in aerial digital photogrammetry using geometric data based on trifocal tensor besides photogrammetric data and distance data from LiDAR.
