Problems solved by technology
[0002] In the field of ore body modeling, compared with the geological interpretation line obtained through drilling in geological exploration, the geological interpretation line obtained through geological cataloging in production exploration is more complicated. If the traditional contour line splicing method is used for modeling , it will take a long time, the efficiency is very low, and the quality of the constructed model is not high
In addition, production exploration is carried out every day, which makes traditional modeling methods unable to keep up with the progress of production

The present application discloses an ore body modeling method, device and storage medium based on the normal direction of the intersecting contour lines. The method includes: constructing a virtual network with topological adjacency relationship based on the three-dimensional intersecting contour lines of the ore body; obtaining the normal vector of the intersection point of the contour line based on the PCA method; obtaining the first segment of the polyline in the contour line based on the normal vector of each intersection point Normal vector and / or tail segment normal vector; obtain the normal vector of the middle segment of each polyline in the contour line based on the linear interpolation method; based on the normal propagation, the direction of the normal direction of the polyline is consistent; based on the implicit function Modeling is performed on the polyline after the direction uniformity treatment, and the target ore body model is obtained. Based on the above processing, the normal direction of each polyline of the intersecting contour line that meets the modeling requirements can be obtained, so that implicit modeling can be performed, and the ore body model that changes with production can be efficiently constructed. Promote application prospects.
Description
technical field [0001] The present application relates to the field of modeling, and in particular, to a method, device and storage medium for ore body modeling based on the normal direction of intersecting contour lines. Background technique [0002] In the field of ore body modeling, compared with the geological interpretation line obtained through drilling in geological exploration, the geological interpretation line obtained through geological cataloging in production exploration is more complex. If the traditional contour line splicing method is used for modeling , it will take a long time, the efficiency is low, and the quality of the constructed model is not high. In addition, production exploration is ongoing every day, which can cause traditional modeling approaches to fail to keep pace with production. Modeling is the foundation and premise of digital mine production, and efficient real-time modeling is of great significance for mine production and the advancement...
