摘　　要：三线阵相机是机载数字传感器的一个重要分类，ADS40是机载线阵相机中的代表性产品，其空中三角测量的数据处理与精度分析方法与传统的框幅式影像有所不同。本文在论述线阵影像空中三角测量原理的基础上，对ADS40相机空三测量的诸多问题例如自动连接点匹配、粗差剔除、方差分量估计、GPS／IMU观测值权值设置、坐标转换等进行了深入研究，并对其试验结果进行了综合分析。The three line camera is a kind of important airborne digital cameras. ADS40 is a typical product of airborne linear array camera, whose data processing procedure and accuracy analysis method is different from those of traditional frame images. Based on an introduction of basic principle of aerial triangulation for three line scanner ima- ges, this paper explores deep into several problems of ADS40 camera aerial triangulation, such as the automatic tie point matching, blunder detection, variance component estimation, datum transformation, the weight of GPS/IMU observations in the combined adjustment, coordination conversion an so on, and makes a comprehensive analysis of test results.
