摘　　要：研究多面阵数字航摄仪的影像拼接技术,对于航空影像采集实现高效快速的数字化生产具有重要意义。本文详细研究了多面阵数字航摄仪相机外视场拼接过程中,相机倾斜角度对拍摄图像变形的影响。推导并计算出了双拼、四拼相机、常规相机中相机倾角导致的任意CCD单元的GSD变化倍率。The study on multiple plane array digital aerial photographic camera mosaic technology has important significance, which can help aerial imagery acquisition achieving 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 mosaic in this paper. The formulas on the GSD change ratio of any CCD pixel caused by camera incline in two-mosaic, four-mosaic （DMC） and film camera were deduced and calculated.

关 键 词：相机拼接 倾斜角度 图像变形 GSD变化率
