Abstract

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.

Description

technical field

[0001] The invention relates to the field of road construction in open-pit mines, in particular to a method and system for automatically constructing road networks in open-pit mines based on GPS data. Background technique

[0002] The open-pit mine road network is a road network that truly reflects the geographical location information of the open-pit mine roads and the topological relationship between the roads. It is the basis for the open-pit mine truck dispatching system and mining equipment operation monitoring and management. With the application and development of informatization and intelligence in mines, the demand for automatic construction and rapid update of road networks in open-pit mines is increasingly urgent. Existing road network construction technologies for open-pit mines have problems such as low degree of automation, long cycle, high cost and precision. Inadequate problems, resulting in the dilemma that the construction of the open-air ro...
