摘要
目前数字航空摄影主要有框幅式成像和线阵扫描两种基本成像方式,其中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,ADS80数字航空摄影其高程精度较传统框幅式航空摄影精度高。本文阐述了影响ADS80数字航空摄影测量高程精度的两个最主要因素,进而分析了该摄影方式能够获取高精度高程的原因。
At present, There are two basic imaging method of aerial photography, which are box picture tyre imaging and linear array scanning imaging. ADS80 aerial Photography is belong to linear array scanning imaging. In the actual production, through the precision inspection, ADS80 aerial photography has a better elevation precision than the box pic- ture type aerial photography. In the paper, Expounds two major factors, which affect the measurement precision of eleva- tion of ADS80 aerial photography. Analysis of the causes, that why ADS80 aerial photography can obtain high precision elevation.
