Abstract
A generation system and method for a high-precision three-dimensional navigation map of a fully mechanized mining surface, applicable to use in the technical field of unmanned mining. The generation system comprises a channel wave seismometer, a laser radar, a combined navigation device, a ground penetrating radar, and a data processing unit; the data processing unit acquires data collected by sensors; perform coordinate conversion, feature fusion and consistency processing on the collected data to generate a Delaunay triangle network of a coal seam, a fault/fold, and a roadway; draw a high-precision profile map of the triangle map, calculate a topological relation of the profile map, generate a topological data structure of the profile map, establish a navigation information automatic query database platform based on the high-precision profile map, and construct the high-precision three-dimensional navigation map of the fully mechanized mining surface. The high-precision three-dimensional navigation map generated by the present invention can provide accurate thickness information of the coal seam, a varied dip angle of the coal seam and a position of a dangerous geological structu…
