Automated Processing of Laser Scanning Data for Three‑dimensional Modeling of Open‑pit Mining Workings in Nanocad Reclouds

The paper considers an automated workflow for processing mine-surveying and geodetic information obtained by laser scanning of open-pit mine workings and bulk material stockpiles. The study aims to develop a consistent method for converting an initial point cloud into a digital three-dimensional model suitable for terrain analysis and material volume calculation. Data processing is performed in the nanoCAD environment using the ReClouds configuration. The proposed workflow includes importing a PTS point cloud, adjusting visualization parameters, removing noise and foreign objects, generating a 2.5D triangulated irregular network, contouring, simplifying and merging mesh fragments, calculating volumes, and applying raster textures.
