有理函数模型实现影像点定位和纠正的方法

The Method of Imaging Point Positioning and Imaging Rectification by Rational Function Model

随着新型传感器的技术发展 ,特别是高分辨率商用卫星的运行 ,有理函数模型 (RationalFunctionModel,RFM)在解决影像点定位和影像几何纠正方面的优越性体现得越来越明显。文中首先介绍RFM模型的原理和应用特点 ,然后结合典型的实际数据进行试验。结果表明通过适当的模型设计完全可以满足影像点定位和影像图生成的要求。

With the development of the new sensor, especially the circulation of the high resolution commercial satellite, The advantage of the Rational Function Model(REM) becomes predominant in resolving imaging points positioning and imaging rectification. This paper respectively introduces the common theory and predominance of RFM applying, and combines the typical practice data with the test. As a result, the proper model designing can meet the demand of imaging points positioning and producing image maps.
