Problems solved by technology

Marcus (2001) designed a visual spatial analysis tool, but it can only analyze and query the simple space-time and structural relationships between geological objects in the 3D model, and there are still many researches to be carried out and continued
[0006] 2) The design of interactive analysis and prediction operation methods in the virtual scene is complicated, and it is difficult for geologists to master
At present, geoscience simulation systems developed at home and abroad, such as GOCAD (2007) by the Mallet development team and geological modeling system by Qu Honggang of Peking University (2008), generally provide a complex interactive operating environment, and only those who have undergone a considerable period of professional training Specialized personnel can master it, and general users (especially end users who are actually operating at the grassroots level in the geological and mining department) are basically unable to use these geological simulation visualization systems proficiently
[0008] 3) The response speed of visual analysis of large-scale geological spatial data is slow, which cannot meet the needs of real-time rendering
However, due to the limitations of the software and hardware technology of the PC, the response speed to the visualization and visual analysis of large-scale geological spatial data is still very slow, which cannot meet the needs of real-time rendering

Abstract

A visual analyzing and predicting method based on a virtual geological model is finished by depending on an interactive visual tool. The method mainly comprises steps of searching a multi-dimensional geological data model from a database and a file system; arranging or resetting a virtual geological scene by setting or regulating corresponding parameters and models; regulating coordinate, scale, data format and the like, of the geological model; sending results of visual calculating, analyzing, predicting and searching into a dual-display cache region; and integrally displaying geological data in a visual platform at real time. The method meets requirements of earth science application, enhances representability of geological data, improves comprehension and application environment of geological data, converts logical thinking of geologists into a trial ground having an imagery thinking of time and space in a virtual environment, helps strengthen deep recognition to complex geological phenomena, uncovers deep information and internal relation in geological data, digs out and extract knowledge unable to be obtained in a traditional mode, improves utilization rate and geospatial analytics of information, and provides a brand-new method for geologists to observe, explain, analyze and imitate geological phenomena in a three-dimensional space, predict and know geospatial distribution of geological structure in a studied area through known data, and obtain mine position, mine reserves and other important information. Furthermore, the human-computer interactive tool is simple and easy to learn to operate, saves cost, reduces blindness in application, reduces risk, conducts and makes decision for production and environment analysis and has significant economic and social benefits.

Description

technical field [0001] The invention relates to the fields of computer technology and exploration geology technology, in particular to a visual analysis and prediction method in a three-dimensional geological simulation system. Background technique [0002] Scientific visualization is a new research field proposed and developed by developed countries in the late 1980s. It is a key research topic in the application of engineering science today. Its technical level is developing from background processing to real-time tracking and interactive control. The theory, method and technology that the data and its changes and final results involved in the process of calculation, analysis, prediction, etc. are directly displayed in the form of graphics and images and processed interactively. Various concrete or abstract geological models can be displayed in real time, visually and intuitively through visualization technology. In the early 1990s, the theory and technology of three-dime...
