摘　　要：通过分析航空摄影测量规范和像点位移误差对航测成图精度的影响,认为造成这一问题的主要原因是我国航空摄影测量规范没有对像点位移误差做出相应的合理限制,而由像点位移误差导致的。It is a difficult problem to improve the image definition of aerial photograph for many years. This paper analyzed the effect of aerial photogrammetric specification and image point displacement error to the precision of aerial photogrammetric mapping. It presented that the main case is no reasonable limitation to image point displacement error in aerial photogrammetric specification of China, and image point displacement error causes the problem

关 键 词：航空摄影 像点位移 系统误差
