Embodiment Construction
[0073] The technical solutions in the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0074] The traditional information collection of structural planes of rock mass requires operators to measure and collect structural plane information one by one in the field, which has the disadvantages of heavy workload, high risk, low precision and poor data integrity. Although there are also relevant studies on the application of 3D laser scanning technology to geological information acquisition, it still requires operators to spend a lot of time searching for structural p...

The invention discloses a rock mass structural plane and occurrence information rapid extraction method, equipment and a medium, which are used for carrying out sub-node segmentation on the spatial range of all point cloud data, solving the problem that the point cloud data cannot be processed or the processing speed is slow due to large data volume, and improving the extraction speed of the rock mass structural plane. Potential structural plane polygons in slope point cloud data are automatically extracted through a peak value clustering algorithm and a DBSCAN algorithm, it is not needed to manually spend a large amount of time to search structural plane information from massive point clouds, the problems of missed classification, wrong classification, inconsistent interpretation standards and the like are avoided, and the structural plane extraction speed and extraction precision are greatly improved.
Description
technical field [0001] The invention belongs to the technical field of rock mass structural plane recognition, and in particular relates to a method, equipment and medium for quickly extracting rock mass structural plane and occurrence information based on three-dimensional laser point cloud data, which breaks through the time-consuming and labor-consuming manual interpretation in the past. And the technical problem of low precision is mainly applicable to the field of engineering geology in hydropower, water conservancy, highway, railway and other industries. Background technique [0002] Rock mass structural plane is a planar geological interface with different scales, complex shapes and intricate distribution formed inside the rock mass. Its occurrence characteristics affect the strength, deformation, seepage and stability of the rock mass to a certain extent. Statistical information on the occurrence of rock mass discontinuities is an important part of geological survey ...
