摘要
DOM的数字微分纠正通常要用到DEM来实现地形的纠正,DEM的精度会在多大程度上影响DOM的纠正精度,是很多技术人员所关心的问题之一。本文通过详实的论证得出了一些结论,为航空摄影各项技术指标的确定、合理有效地选取DEM数据源等问题作了科学的回答。
DEM is usually used to realize the topographic in the differential correction in DOM. To what extent is the accuracy of DEM affecting the correction accuracy of DOM is a primary concern for many technicians. By detailed argumentation, the article gives a scientific answer to the question of how to confirm all technical indexes of the aerial photograph and how to choose the data sources of DEM rationally and effectively.
