Extraction of Step-Feature Lines in Open-Pit Mines Based on UAV Point-Cloud Data

Step-feature lines are one of the important geometrical elements for drawing the status quo maps of open-pit mines, and the efficient and accurate automatic extraction and updating of step-feature lines is of great significance for open-pit-mine stripping planning and analysis. In this study, an aut...
