The Method of Mass LIDAR Point Cloud Visualization Based on Point Cloud Pyramid

摘要：

Build a Point Cloud Pyramid data model similar to the image pyramid by analyzing the mass LIDAR point cloud data and image data in common and learning image pyramid data model and its construction method; Create the data model by rarefy and blocking the mass point cloud. Then construct a quadtree spatial index and figure out a quadtree searching method to achieve the purpose of mass point cloud visualization by dynamic reading and displaying base on, the spatial location and scale. Finally, realized this method and proved its feasibility.
