Abstract

The invention provides an automatic construction method and system for a road network of open mine. The method comprises: obtaining pre-acquired GPS point data of the road network of the open mine; according to a transverse span Xspan and a longitudinal span Yspan of the GPS data distributed in space and the precision Tol of the road network, constructing M*N grids; initializing a binary image with a pixel of M*N, and according to the number of GPS points located in each of the M*N grids, assigning a pixel point corresponding to the grid in the binary image with a value of 0 or 1; by using a Hilditch thinning algorithm, extracting a framework of the assigned binary image subjected to value assignment, and obtaining the grid road network of the open mine; and by using a grid image vectorization method, vectorizing the grid road network of the open mine to obtain a topological relationship network of an open mine road. The automatic construction method for the road network of the open mine can realize automatic construction of the road network of the open mine.

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. 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 road network cannot ...
