摄影测量外业控制点的布设与测量

摘要

Photogrammetry field work is directly related to the match accuracy and the level of orthographic projection. It is an important task to layout the control points reasonably and determinate the position accurately in field surveying. Beginning with analysis of importance of control survey, the paper summarizes the method and principle of control point in field sur-veying. Then it puts forward reasonable selection method of control points from accuracy requirements and some suggestions for the future development of control survey.%摄影测量外业工作直接关系到影像最终匹配精度和正射投影水平，合理布设外业控制点，精确测定控制点位置，是一项重要任务。文章从摄影测量外业控制测量的重要性入手，总结了外业控制点的布设方法和原则，并从规范和影像应用精度要求合理选择控制点的施测方法，并对未来外业控制测量发展方向提出了建议。
