Description

technical field [0001] The invention relates to the field of three-dimensional geological modeling in geological survey and exploration, in particular to a multi-tool collaborative three-dimensional geological modeling method and system for multi-source data. Background technique [0002] Three-dimensional modeling of geological objects is required in geological survey and exploration. Due to the different ages and reasons for the formation of different geological bodies, different geological bodies have extremely complex topological relationships in space; especially the appearance of immersion bodies, folds and fault dislocations makes geological bodies more diverse in shape. transsexual. In order to make the different types of geological body models better reflect their actual shape, they must be classified and modeled using different methods. Geological bodies can be divided into layered entities, massive entities, faults and folds according to their shape. At present...

Problems solved by technology

[0005] However, due to the complexity and diversity of geological conditions, and the limitations of modeling software in terms of modeling methods and functions (for example, C Tech software has advantages in building fine stratigraphic models, but cannot build ore body models, for strata and In the area where the ore body exists at the same time, the complete geological model of the area cannot be constructed only by using C Tech software), and the user needs to select the corresponding software to complete the 3D modeling according to different geological conditions. The process of selecting software and modeling process are relatively complicated. low work efficiency

[0006] In addition, in the past ten years, scholars at home and abroad have proposed a variety of spatial data models and modeling methods around 3D geological spatial modeling, but most of the spatial data models and modeling methods are based on simple software and data sources. For layered geological body modeling, due to the limitation of functional characteristics of some software, the types of models built by the software or the data sources that can be used are limited, which makes the modeling accuracy and modeling efficiency of 3D modeling through a single software relatively low. Low, poor modeling effect
