Abstract :
The study on multi-format aerial digital camera mosaic technology has important significance. Which can cause aerial imagery acquisition achieve digital production with high efficiency and speediness. The image distortion caused by camera incline was studied particularly in the process of multi-lens aerial digital camera exterior marriage in this paper. The formulas on the Ground Sampled Distance(GSD) change ratio of any pixel caused by camera incline in two-mosaic, four-mosaic and aerial camera were deduced and calculated. Finally the conclusion how to design the obliquity of single camera in multi-lens aerial digital camera was gotten.
