| 摘 要： | ADS40是一种集成POS的新型高分辨率机载三线阵扫描数字传感器,飞行过程同步记录影像数据和POS数据。POS的精度不能满足高精度的制图应用,要获取更高精度、更高可靠性的定向数据,必须进行空中三角测量。从共线条件方程出发,结合线阵影像的成像特点,用两种方法推导并建立光束法平差的数学模型并给出试验结果。

| Abstract: | ADS40 is a new style airborne high resolution multi-line~() push broom imaging sensor integrated with GPS/IMU and developed by L.H Corporation.To obtain the highest possible accuracy and reliability a triangulation is required.Because of push broom principle mathematical modelling is more complex than the collinearity equation used in classical bundle triangulation.The paper provides adjustment math models of piecewise polynomial fit and Lagrange polynomial interpolation for aerial ADS40 Sensor based on collinearity equation.Experiment results show its right. |
