输电线路测量软件中坐标系统的转换与处理

Conversion and Processing of Coordinate System in Transmission Line Survey and Design Software

输电线路测量软件的开发必然需要考虑坐标系统,其核心内容是计算机坐标系与线路坐标系的转换。通过坐标系的转换实现屏幕图元的平移、缩放,以及图形界面视图的开窗、全图显示等。本文详细论述了输电线路测量软件涉及的计算机坐标系统与线路坐标系统的关系与相互转换方法,并在开发的线路测量软件中进行应用。

The coordinate system must be considered in the development of transmission line survey software.The core content is the transformation between computer coordinate system and transmission line coordinate system.Specifically related to the coordinate system translation,zooming,rotation,as well as the window view,the full view and so on.In this paper,the relationship between computer coordinate system and line coordinate system involved in transmission line survey software and the method of mutual transformation are discussed in detail,and applied in the developed transmission line survey software.
