Summary

The monitoring of highwall slopes at open-pit mines is crucial for safe mining, and several techniques like total station, radar, and terrestrial Light Detection and Ranging (LIDAR) can be used for surface measurement. This study investigates mesh algorithms for interpolating 3D models of pit walls using terrestrial LIDAR data. Experiments were conducted at two mines, and three algorithms (Delaunay 2.5D XY Plane, Delaunay 2.5D Best Fitting Plane, and Mesh from Points) were used to generate mesh surfaces. The results showed an average distance between the surface and point cloud of 5.6-5.8 mm with a deviation of 6.2-6.8 mm. The accuracy of computed NURBS surfaces was 4-5 times lower than that of optimized mesh fitting, but still allowed for determining displacements on the level of centimeters.
