摘要
本文以航空摄影测量像片为分析对象．根据中心投影的特性，论述了像片在倾斜条件下所引起的像点位移和像片因地面起伏而引起的像点位移，在对其进行分析的基础上总结出倾斜误差和投影误差的规律，从而说明了不能把像片当作地形图使用．
In this paper, according to the characteristics of central projection, aerial photographs were analyzed to discuss displacement of images under tilt conditin or caused by ground undulation, based on which the principles of tilt error and projection error were summarized. Thus, it was indicated that photographs could not be used as topographic maps, which was essential for utilization of aerial photographs.
