摘要：To improve the effect of Lidar data, and utilize the intensity information of Lidar data, according to the character of Lidar data, a new fusion mean filtering algorithm based on the flatness degree of terrain is proposed. The algorithm uses a new fusion mean filter which is fused the elevation information of each pixel's neighborhood, to deal with the intensity image. The algorithm and mean filtering algorithm are applied in Lidar data, and their results are compared in different evaluation indexes. The result shows the proposed algorithm has some improvement in keeping the advantage of mean filtering algorithm under the condition of preserving unclear edges of the image
