Software used to extract discontinuity sets from point clouds

Abstract

Slope failure has always been a problem for geotechnical engineers. Rockfall is a widely seen natural disaster in mountainous terrain. Rock slope stability is mainly controlled by fractures. Accurate modelling the rockfall event is crucial to lessen the damage came from the rocks. Traditional compass method is time-consuming and dangerous at steep slopes. Remote sensing techniques such as photogrammetry and laser scanner are new techniques to obtain geotechnical data. Geospatial information of the object can be obtained easily. This data contains 3D coordinates with color and intensity information. In this study, we have revealed the software that can automatically detect and extract geotechnical data from point clouds. Discontinuities in the rock mass can be easily obtained with high accuracy and precision with these software packages.
