控制点样本快速制作思路及实现方法

The idea and implementation method for rapid production of control point sample

外业控制点是检测正射影像成果质量的重要手段。依靠人工作业生产外业控制点样本存在信息重复、标记绘制困难、无法计算裁切范围和无法保证格式统一等缺点,严重制约项目的推进和数据质量的提升。本文使用ArcPy脚本、ArcEngine接口和地图模板技术,设计实现控制点样本文件的快速制作的方法。经某项目的生产验证,结果表明,该方法能够有效减少工作强度和出错概率,提升控制点样本的制作效率。

Field control point is an important means to detect the quality of orthophoto results.The production of field control point sample relying on manual operation has some shortcomings,such as information duplication,difficulty in marking,inability to calculate the cutting range,and inability to guarantee the uniform format,which seriously restricts the progress of the project and the improvement of data quality.This paper uses ArcPy script,ArcEngine interface and map template technology to design and implement a rapid production method of control point sample file.The production verification of a project shows that the design method can effectively reduce the work intensity and error probability,and improve the production efficiency of control point sample.
