Unmanned aerial vehicle-based surface mine floor elevation measurement method and system

Abstract

The invention belongs to the technical field of bottom plate elevation measurement, and discloses a surface mine bottom plate elevation measurement method and system based on an unmanned aerial vehicle. The method comprises the following steps: setting a plurality of measuring points for measuring the elevation of the bottom plate; measuring the elevation of the bottom plate by using an unmanned aerial vehicle; acquiring a drill hole center coordinate data set formed by the central drill hole and the plurality of adjacent drill holes; orderly arranging the drilling hole center coordinate data set; the two adjacent drill holes and the center drill hole are divided into corresponding triangular areas; obtaining triangular centroid coordinate data of each triangular area, and adding the arranged drill hole centroid coordinate data set to obtain a target point coordinate data set; obtaining a target point bottom plate elevation measurement data set; traversing all drill holes of the surface mine; and obtaining cloud picture data according to the base plate elevation measurement data set of all the target points, and performing visual display. According to the invention, the problems of high cost investment and low data value in the prior art are solved.
