摘　　要：针对ALOS PRISM三线阵传感器,综合镜头光学畸变、像元尺寸和主距变化等影响,构建内定向参数模型;同时利用多项式模型,描述影像的外方位元素变化特征,建立自检校光束法区域网平差模型。利用ALOSPRISM实际数据对内定向参数模型进行研究和优化。结果表明,合适的内定向参数模型能起到良好的定标效果。For the three liner-array sensor of ALOS PRISM, an orientation parameter model was constructed on the base of the factors of sensor distortion, pixel size zooming, focal length zooming and so on. A polynomial model was used to analyse the variational character of exterior parameters. Then a self-calibration bundle block adjustment model was constructed. Using ALOS PRISM reality data, the orientation parameter model, was re- searched and improved. Experimental results proved that the appropriate orientation parameter model could get a good calibration result.
