Integration of LiDAR and Photogrammetric Data
This chapter starts with a brief discussion on the principles of Light Detection and Ranging (LiDAR) and photogrammetry. The discussion on photogrammetric principles is focused on incorporating frame and line cameras in a single triangulation mechanism. Several mathematical models are then presented for incorporating straight lines and planar patches into the triangulation procedure of LiDAR and images. For the subsequent task of true orthophotogeneration, this chapter introduces two new methods as alternatives to the conventional ones. Finally, the feasibility and the performance of the developed multiprimitive and multisensor triangulation methodologies are demonstrated by experiments using overlapping LiDAR data, aerial images, and satellite images.
