Three-dimensional surface modeling method and system for section reconstruction based on polygonal deformation technology

Abstract

The invention discloses a profile reconstruction three-dimensional surface modeling method based on the polygon deformation technology and a profile reconstruction three-dimensional surface modeling system thereof. The method comprises the steps that a single engineering ore body boundary automatic delineation method meeting two types of lithology of uranium ore sandstone and hard rock is designed and realized by using the special rules (requiring consideration of the characteristics of the independent square meter quantity of uranium and meter percentage parameter of the uranium ore and ore body lithology penetration in the geological stratification) of uranium ore body delineation. A complex uranium ore body boundary is delineated on the profile map accordingly with combination of the ore area geological data. Then the delineated ore body boundary acts as the complex ore body contour to be projected to a three-dimensional visual platform, and three-dimensional surface reconstruction of the uranium ore complex ore deposit structure based on the contour line is realized through combination of polygon deformation and the interpolation algorithm and applied to three-dimensional geological modeling based on the profile. The similarity between the contours in contour three-dimensional surface modeling based on the profile can be enhanced, the contour space between the profiles can be reduced and fine modeling of the complex three-dimensional geological body can be realized.

Description

technical field [0001] The invention relates to the field of three-dimensional geological modeling in geological information technology, in particular to a three-dimensional surface modeling method and system for section reconstruction based on polygon deformation technology. Background technique [0002] In the process of geological and mineral exploration and its informatization, 3D geological modeling is an important research direction, and has important application significance in exploration and development and resource management. Uranium ore is a special mineral resource. Due to its own strategic significance and resource protection significance, compared with other solid minerals, the degree of informatization and digitization of uranium ore exploration work is not high on the whole. Through the long-term hard work and hard work of several generations of geologists in geological brigades and scientific research institutes related to the geological, mining and nuclear...
