摘要
目前航空摄影主要有框幅式和线阵扫描两种基本成像方式,ADS航空摄影是线阵扫描航空摄影的一种。通过实际生产精度检查发现,ADS 80数字航空摄影的高程精度较传统框幅式航空摄影精度高。本文阐述了影响ADS 80数字航空摄影测量高程精度的两个主要因素,分析该摄影方式能够获取高精度高程的原因。
Frame image and line array scanning image are the two basic mode of imaging in current aerial photogrammetry.ADS aerial photogrammetry is a kind of line array aerial photogrammetry.Through practical production accuracy checking,it is proved that the elevation accuracy of ADS 80 digital aerial photogrammetry is higher than that of conventional frame imaging aerial photogrammetry.This paper elaborates on the two main factors that influence the elevation accuracy of ADS 80 aerial photogrammetry,and analyzes the reason of its high accuracy.
