摘　　要：通过对矿区航摄相片中投影差的大小与焦距、航高、地形的起伏大小,及地物的高低等要素的关系进行了分析,从而对矿区正射影像图变形产生的原因进行了总结,并且对如何减少投影差对矿区正射影像图变形的影响加以研究,以及快速修改变形的方法。Based on the mining area the size of the projection in the aerial photo and the focal length, flying height, and the size of the terrain ups and downs, and the features of the relationship between the elements such as are analyzed, and the mining area are the causes of projective like figure deformation are summarized, and on how to reduce the difference of projection is the mining area to study the influence of projective like figure deformation, and the method of deformation of rapid change.
