The invention provides a GPS data based automatic construction method and system for open-pit mine road network . The method comprises: S1, constructing an initial triangulation network of GPS point data by using a scattered point Delaunay triangulation algorithm according to pre-collected GPS point data of the open-pit mine road network; S2, filtering the initial triangulation network to obtain a road triangulation network; S3, extracting an opening line of the road triangulation network to construct a road double-line network and form a road multi-communication region; S4, constructing a road multi-communication region triangulation network by using a multi-communication region triangulation algorithm; S5, traversing triangular shapes in the road multi-communication region triangulation network to extract feature points of each triangular shape; and S6, connecting the feature points according to the relation between each triangular shape and the adjacent triangular shape in the road multi-communication region triangulation network, so as to form an open-pit mine road topology network. With the adoption of the automatic construction method, the open-pit mine road network can be automatically constructed.
