摘　　要：三线阵机载传感器ADS40为瑞士Leica公司于2000年推出的世界上首款商用三线阵航测数码相机。机载三线阵航测数码相机ADS40独特的硬件设计方式和数据处理方式对传统检校理论方法带来了挑战。基于对ADS40相机文件系统误差的分析,该文给出了一种基于验后补偿法的ADS40几何检校方法。采用一组低阶的二元多项式来拟合每个CCD线阵的相机文件系统误差,推导了解算方法,并通过验证实验证明该文给出的算法稳健可靠。ADS40（the LH Systems ADS40 airborne digital sensor） ,which was brought out by Leica in 2000,is the world＇s first commercial three-line array aerial digital camera. The unique hardware design and dataset processing workflow of ADS40 brings challenges to traditional calibration theory and method. Based on the analysis of the ADS40 camera file systematical errors, the test field calibration combined with posteriori compensation method of ADS40 is proposed. With a group of low-level binary polynomial used to fit the systematical errors of every CCD linear array, the solving method is derived, then the verification of experiment it proves that the proposed method is robust and reliable. through
