| 摘 要： | 充分利用无人机载GPS/INS组合导航系统提供的导航遥测数据,首先分析线阵CCD传感器摆扫成像的基础原理和成像特点,并建立严格的成像模型;然后提出线阵摆扫CCD影像严格几何校正的详细算法和流程;最后进行多组实验证实成像模型和几何校正算法的正确性和准确性。实验结果证实采用文中的成像模型和几何校正流程,可获得正确、高精度地理编码的线阵摆扫CCD正射影像。

| Abstract: | Based upon the navigation and location data provided by the GPS/INS integrated navigation system aboard on the pilotless aircraft,in the paper a strict imaging model is first set up for the linear whiskbroom CCD imagery after a comprehensive consideration on its imaging characters,and then a detailed flow is for its rectification,finally the correctness and precision of the proposed imaging model and rectification flow are testified through experiments.Tests prove the imaging model and the rectification flow proposed in the paper is correct for obtaining high accurate linear whiskbroom CCD orthoimagery. |
