Abstract

Abstract:

To address the parameter optimization challenge of airborne LiDAR technology in 3D modeling of complex mine terrains and enhance modeling accuracy and efficiency, a systematic study was conducted. Firstly, the principles of airborne LiDAR data acquisition, the composition of the measurement system, and the data processing process were analyzed to clarify the basic logic of the technical application. Then, combined with the characteristics of the complex terrain of mine slopes, the parameter requirements for flight routes, flight altitude, and overlap in airborne LiDAR data acquisition were proposed, and the optimal data acquisition scheme was formed to obtain high-precision mine slope data. Finally, the feasibility and effectiveness of the proposed scheme were verified through a 3D modeling test on the slope of an open-pit mine. The results show that the optimized data acquisition scheme can improve the accuracy and efficiency of data acquisition and 3D modeling; the built model can provide data support for slope stability analysis and deformation monitoring.

Key words: airborne light detection and ranging (LiDAR), 3D modeling, point cloud data, data acquisition, stability analysis
