摘　　要：将基于附加参数的自检校光束法区域网平差技术应用于机载三线阵CCD传感器ADS40影像的几何定位处理,分析了机载三线阵CCD传感器成像的误差特性,建立了相适有效的自检校附加参数模型,以及3种形式的外方位元素变化模型和自检校光束法区域网平差模型。实验结果表明,自检校光束法区域网平差能够有效补偿ADS40影像存在的系统误差,显著提高定位精度。The self-calibration block adjustment based on the additional parameters is applied to ADS40 imagery geometric positioning.Upon the detailed investigation on the imaging error properties of the three-line-scanner CCD sensor,the suitable self-calibration parameter model is built up.Then three types of exterior orientation parameter models and the self-calibration block adjustment model are set up.Finally the normal block adjustment test and the self-calibration block adjustment are carried out using the ADS40 data.Experimental results prove that the self-calibration block adjustment technique can efficiently compensate the system errors of ADS40 image and significantly enhance the positioning accuracy.
