Research on The Application of Laser SLAM and Visual SLAM Technology in The Exploration and Management of Underground Environment in Mines
With the development of"digital intelligence"mine construction,green low-carbon development and diversified technological innovation,the traditional measurement method relying on GNSS signal is widely used in open-pit mine geological environment exploration.In view of the problems of poor signal,low operation efficiency and low measurement accuracy in underground environment,the research on the application method of mine underground environment exploration and management is relatively insufficient.In this paper,high-precision 3D point cloud data and high-resolution image data of underground mine tunnels are obtained by combining laser SLAM and visual SLAM technology,and then the point cloud data and image data are matched and fused to construct a refined three-dimensional model of underground mine tunnels.Based on this model,the accurate geological structure,three-dimensional numerical value and other characteristic information of mine underground environment can be obtained qualitatively and quantitatively,which can provide scientific and effective technical and data support in many links such as mining optimization,residual ore recovery,goaf filling,safety monitoring and management of mine underground environment exploration and construction.
