摘　　要：基于Leica公司提供的ORIMA软件,利用武汉大学自行建设的登封航空定标场,对三线阵机载传感器ADS40在不同航线结构、不同控制点数量以及不同平差模型下的几何精度进行了对比分析和评估。实验结果证明,控制点数量和构架航线对ADS40几何精度影响有限,但自检校平差模型可以显著提高其几何精度。Based on the ORIMA programs produced by Leica, by using the Henan Song mountain calibration test field built by Wuhan University, the attainable geometric accuracy of the three-line-sensor ADS40 imagery was evaluated. In this experiment, three main scenarios were considered in detail, namely different control strips, different control points configurations and different bundle adjustment models. And its results prove that, in basic camera model the number of control points and control strips have limited effect on data accuracy of ADS40, while in self-calibration model, it can significantly improve its geometric data accuracy.
