摘要
有理函数模型是各种传感器几何模型更广义和更完善的一种表达形式 ,它适用于各种不同的传感器。许多卫星影像供应商考虑使用这种模型作为影像数据的传递标准。文中在分析RFM的基础上 ,结合航空影像和SPOT影像数据对RFM进行了研究。试验结果表明有理函数模型可以达到严格成像模型的精度 ,并且有能力替代严格成像模型完成摄影测量处理 。
The Rational Function Model has recently gained interests in remote sensing community. It is a kind of generic and expressive model, and it is applicable to all types of sensors. Due to these attractive characteristic, many satellite imagery vendors have considered this model as an image data transfer standard. The RFM was presented ten years ago, however publications regarding the theoretical properties and empirical experiment about the use of RFM have hardly been found. For better understanding of RFM, we discuss their properties. The experiment with aerial images and SPOT images has been carried out and summarized, which shows that the accuracy of RFM is as the rigorous model, and that RFM can take place of the rigorous model to complete the Photogrammetrc processing,at the same time the meaningless ration coefficients can hide the sensor's imaging information effectively
