AutoCAD数据的坐标系统转换方案研究

A Study of the Plan of Coordinate System Conversion of AutoCAD Data

提出了进行AutoCAD数据坐标系统转换的新方案。该方案利用AutoCAD数据区域内的、在两个不同坐标系统中的公共点坐标值,求得该区域的七参数,然后在Visual Studio环境中,加载AutoCAD提供的类库,利用七参数解求图形在新坐标系统中的坐标串,形成一个新的AutoCAD数据文件。本方案操作简便,转换效率高,精度好。

This paper puts forward a new AutoCAD Data coordinate system conversion scheme which obtains the seven parameters of AutoCAD data area,loads AutoCAD class libraries in Visual Studio environment,obtains the image coordinate chain in new coordinate system,and forms a new AutoCAD data file using coordinate value of common points in two different coordinate system in AutoCAD data area.This scheme is simple in operation,high in conversion efficiency and accuracy.
