ADS80影像数据制作DOM的精度控制

Accuracy Control of DOM Production Based on ADS80 Image Data

通过两个实验区,应用X-pro、Orima软件,在空三加密、坐标转换、DEM编辑、DOM生成等工序环节,利用CQG2000似大地水准面成果,采取设置检查点、自由网平差和特殊区域区别对待的DEM编辑方法等措施,实现ADS80航摄影像数据制作DOM的精度控制。

By taking two experimental areas as the examples, the paper uses X -pro and Orima software as well as CGCS 2000 quasi - geoid data to achieve the accuracy control of DOM production ADS80 image data through the way of check point setting, free net- work adjustment and DEM editing methods particularly for different areas in the aerial triangulation, DEM editing and DOM produc- tion.
