浅谈IMU/DGPS技术在1∶10000比例尺地形图测绘中的应用

Discussion on the Application of IMU/DGPS Technology in Surveying and Mapping of 1∶10000 Topographic Map

通过IMU/DGPS技术在实际测绘生产项目中的应用,研究该技术条件下1∶10 000比例尺地形图测绘外业像控布设方案,试验、分析内业空三加密精度,调整像控方案,最终为IMU/DGPS技术在1∶10 000比例尺地形图测绘中的应用提供相关的技术参考。

Through the application of IMU/DGPS technology in practical surveying and mapping production project,this paper studied the layout plan for field photograph control survey of 1∶10000 topographic map,tested and analyzed the accuracy of triangulation,and optimized the scheme of photograph control survey.Finally,it provided the technical reference for the application of IMU/DGPS technology in surveying and mapping of 1∶10000 topographic map.
