Optimization of LiDAR System Ortho-image Mosaic Seam-Line

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.
