Optical registration analysis of multi-spectral airborne camera with multi-lens

摘要

Optical registration requires the same spatial coordinate of all the corresponding pixels in the multi-spectrum images. The imaging equation of the multi-lens camera is established in the same ground coordinate. Some factors are analyzed and simulated with the actual parameters of a multi-spectral camera. The ground coordinate differences are compared among these factors, and the results are shown in paper. The shutter delay between the camera shutter and POS should be considered firstly, and the influence by focal length is more marked than the influence by angle of optical axis. The multi-spectral cameras should be selected to keep higher shutter synchronism.
