摘要
提出了一种基于改进的Harris角点检测的航空遥感影像镶嵌方法。该方法增加了水平、垂直方向的梯度检验,用于提高整个算法的运算速度;增加了自适应阈值的确定算法,提高了整个算法的鲁棒性,实现了航空影像间的自动配准,最终使用加权平滑算法完成了图像的无缝镶嵌。整个处理过程完全自动地实现了对两幅航空遥感影像的无缝镶嵌,克服了传统航空遥感影像镶嵌在属性条件变化下的局限性,实验结果验证了方法的有效性。
An automatic aerial remote sensing image mosaic method based on improved Harris corner detection is proposed. The horizontal and vertical gradient test is added to improve the speed; the auto-adapted threshold is added to improve the robustness. The automatic registration between images is realized. And finally image mosaic is completed with smoothing algorithm. The method implements automatically and avoids the disadvantages of traditional aerial remote sensing image mosaic method under different attribution conditions. Experimental results show that the method is stable and effective.
