摘要
传统航空摄影测量是在立体环境下采集地形、地貌数据,生产成本高,效率低。本文探讨使用ADS100数据源,利用XPRO完成空三加密,再用Inpho软件进行内业处理,通过控制好作业流程的每一步骤的质量,生产高精度的DTM,反演等高线数据。该技术能为基础测绘提供高质量的地形数据,为实现自动生成等高线数据奠定基础,大大提高了基础测绘内业的工作效率,降低了生产成本。
The traditional aerial photogrammetry collects topographic and geomorphic data in three-dimensional environment,which has high production cost and low efficiency.Using the ADS100 data source,this paper applies the Xpro software to completing the aerial triangulation measurement,and then uses Inpho software for internal work processing,by controlling the quality of each step of the operation process to produce the high-accuracy DTM,which is used for contour generation.This technology can provide high quality topographic data for basic surveying and mapping,and lay a foundation for automatically generating contour data.It can greatly improve the working efficiency of basic surveying and mapping internal work and reduce the production cost.
