摘要
控制点在遥感影像纠正等应用中有着非常重要的作用。本文针对人工选取控制点效率低、精度差的问题,提出了Google Earth高分辨率遥感影像控制点自动提取方法,说明了基于线特征确定稳定控制点的方法,并通过遥感图像纠正以及航拍图像定位实验验证了方法的有效性。
Control points play an important role in remote sensing image correction and other applications. In view of the low efficiencyand poor precision of the artificial control points, the automatic extraction technology of Google Earth high resolution remote sensingimage control point is proposed, and the method of determining the stable control point based on the line features is explained. The validity of the method is verified by remote sensing image correction and aerial image location experiments.
