摘要
结合某区域的1∶10 000测图任务,在分析利用POS辅助空三数据建立立体模型流程的基础上,探讨了立体模型建立过程中的相关技术要点,包括相机文件的创建、航线列表的建立、控制点的引入、高程异常模型的引入及相对定向的人工编辑等。最后对建立的立体模型进行精度检测,结果表明:立体模型的精度可满足1∶10 000测图要求。
Combined with the task of 1:10 000 digital mapping, this paper analyzed the process of three -dimensional model building with data of POS supported aerial triangulation, discussed the main technical points in the process, including the camera file creation, the air line building, the control points importing, the height anomalies model importing and manually editing in the process of relative orientation. Finally precisions of the three - dimensional model built are tested, results showed that precisions meet the requirement of 1:10 000 digital mapping.
