Application of POS in correcting images of aero-digital camera with large format array CCD

In projection Aero-Digital Camera with Large Format Array CCD, High Resolution, Large Field of View and Multi-mode, three cameras with 4k×4k CCD sizes are integrated separately in three modes, including large field of view mode, multi-spectral mode and stereophotography mode. Such methodology make one camera system to meet different roles according to the different setting ways before flight missions. Correspondingly the different modes have different geometric characteristics, and the situation looks like more complicate with some additive factors' variations of aircraft, such as pose, speed, height, and so on.The POS/DG system was carried in flight to aid to the upper geometric correction of CCD images. Some flight pose parameters, such as precision location coordinate, flight pose, dynamic variations etc. were directly used in the geometric correction models. One processing example is also provided in this paper.
