Optimization of LiDAR System Ortho-image Mosaic Seam-Line

    摘要
  • 摘要: 在机载LiDAR系统中,将点云数据进行滤波以去除高地物,确定出房屋树木等高出地面的地物的位置记为障碍区域。在配准后的正射影像上,利用改进A*算法自动避开障碍区域选择一条最优化镶嵌线。实验证明,该方法可以准确、智能地对镶嵌线进行优化,改善镶嵌后的影像质量。

     

    Abstract: A detailed study of choosing the best seam-line in image mosaic was carried out in LiDAR system.The tall ground object marked as obstacle can be identified by filtering laser points.And an improved A algorithm was proposed to make the seam-line keep away from the obstacle in the registered image automatically.We found that this method can optimize the seam-line exactly and intelligently to improve the quality of Ortho-image.
