常用CAD与GIS平台影像自动配准方法及实现

Realization of the City Digital Orthophoto Maps for Registering Methods of CAD and GIS Platforms

根据我国大多数城市正射影像图的特点,建立了影像图中像素坐标和实际地理坐标的对应关系,在详细地分析常用CAD和GIS平台中影像图配准方法和影像配准文件结构内容的基础上,采用VB6.0,通过程序代码的编写,实现了常用CAD和GIS平台中正射影像图的自动化、批量化配准,大大提高了影像配准和入库效率。

According to the properties of most city digital orthophoto maps of China,the corresponding relationship of pixels and map coordinates was build.Based on the analysis of registering file＇s contents for CAD and GIS platforms,the automatic registering of the CAD and GIS platforms was realized by VB6.0 and coding.
