摘要：Digital aerial photogrammetry has the virtue of high precision and efficiency, but the plane array of single digital camera is not wide enough, so the land coverage and base-height ratio of single digital camera is smaller than the traditional film camera. So people always array several single digital cameras (usually two or four) together as one camera, and it's called multiple plane array digital photographic camera or mosaic camera, the angle of single digital camera is not level as usual, it circumgyrates around it's own axis of lens to get large land coverage, and it has become the focus in recent research. The tilting angle of single camera is the most important parameter in multiple plane array digital photographic camera system; it determines the image quality and the useful land coverage (effective virtual picture format). 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 GSD change ratio of any pixel caused by camera incline in two-mosaic, four-mosaic(DMC) and film camera were deduced and calculated. It has important significance in the design of multiple plane array digital photographic camera
