摘　　要：本文针对线阵CCD推扫式传感器影像的摄影测量定位处理，介绍了传感器模型的定义、分类以及研究现状，分析了有理函数模型的数学基础、解算以及控制方案，总结了有理函数模型的理论特性。并且通过实验利用模拟数据探讨了各种因素对有理函数模型精度的影响，进一步明确了不同成像条件下有理函数模型的精度潜力和应用可行性。Aiming at the linear array CCD push -broom imagery, the definition, classification and research status of sensor model, as well as the mathematic model, algorithm and control scheme of the rational function model are described. The feature of the rational function model is analyzed and the influence of imaging condition on the RFM accuracy is discussed using simulation data. A conclusion about feasibility and potential accuracy of the. rational function model under different imaging conditions are determined.
