Abstract:Based on 3D laser scanning technology and geological analysis, an experiment was conducted to study the information extracted from structural plane in underground mining engineering. Z+Flasercontrol and Geomagic Studio were used to preprocess the cloud information of surround rock point. A point cloud data processing system was developed by Java language, and the Dips software is used to analyze the information of structural planes. The accuracy and feasibility of this system were validated against the manual measurements. It is shown that this method provides advantages in terms of fast, automatic and distant measurement, compared with the traditional method.
Keywords:3D laser scanning  point cloud data  information extraction  structural plane  manual measurement  underground mine
