ALOS PRISM自检校光束法区域网平差

摘要

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 researched and improved. Experimental results proved that the appropriate orientation parameter model could get a good calibration result.%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；同时利用多项武模型,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.
