Abstract

3D reconstruction of terrain model based on digital line graphics (DLG) is discussed. An auto-coupling triangles algorithm based on triangle topological relationship is put forward, and the topological data model of complicated terrain is developed. Based on this data model, automatic 3D topological reconstruction of terrain is realized.
