摘要
结合某带状区域的1∶10000无控制点测图任务,在分析卫星遥感影像无控空三加密技术流程的基础上,探讨了基于Pleiades影像的带状区域无控空三加密的相关技术要点,包括数据分析与预处理、工程基本参数设置、连接点选取、平差调整、测区接边等,最后对加密成果进行了精度检测分析。结果表明成果满足无控制点条件下1∶10000比例尺测图任务技术设计的精度要求。
Combining the 1∶10000 uncontrolled point mapping task of a certain strip area,based on the analysis of the satellite remote sensing image uncontrolled aerial triangulation technology process,the relevant technology of the strip area uncontrolled aerial triangulation based on Pleiades image is discussed The main points include data analysis and preprocessing,basic engineering parameter setting,connection point selection,adjustment,edge connection of the measurement area,etc.Finally,the accuracy detection and analysis of the encryption results are carried out.The results show that the results meet the accuracy requirements of the technical design of 1∶10000 scale mapping task under the condition of no control points.
