中文摘要：

基于线阵传感器几何特性和误差模型的分析,提出一种不利用地面检校场的无地面控制点检校线阵传感器的方法。从对几何定标各种参数相关性的分析中,提出利用改善航线结构本身的几何条件可以消除或减少参数间的强相关性对解算精度的影响。特别对双航高结构消除主距、主点与高程之间的强相关性作了具体分析,从而实现了无地面控制点的相机自检校过程。然后研究整个工作流程并利用不同相机的实际数据进行检校实验,对生成的新相机参数进行精度验证与分析。结果证实本文提出的方法是可靠和可行的,可有效提高成像数据的几何定位精度。

英文摘要：

Based on the analysis of geometrical characteristic and error model of the linear array sensor, this paper puts forward a kind of linear array sensor calibration method without ground control points（GCPs）, which could not be required for testfield any more. From the analysis of the correlation of the various parameters of the geometric calibration, the geometrical conditions of the flight line structure are provided to eliminate or reduce the correlations among various parameters which affect the accuracy of the calibration result. The special structure of the two-flight levels is discussed to eliminate the strong correlation between principal distance, principal point and height, in order to achieve the camera self-calibration process without ground control points. Research on the whole working process and using different camera data for calibration experiments, the accuracy of the new camera parameters are validated and analyzed. The results confirmed that the method in this paper is completely reliable and feasible, and can effectively improve the geometric positioning accuracy of imaging data.
