AN INTEGRATED SPATIAL INDEXING OF HUGE POINT IMAGE MODEL
In order to manage point image model easier and build the point cloud model on the basis of the need and improve the query efficiency, a 2D&3D integrated spatial index of large point image model is proposed in this paper. Point image is managed by 2D quad tree and 3D MBB. Point image model const...
