Field geological three-dimensional comprehensive information platform and data integration and visualization method thereof

Abstract

The invention discloses a field geological three-dimensional comprehensive information platform and a data integration and visualization method thereof. The field geological three-dimensional comprehensive information platform comprises a browsing query and query result output module which realizes two-dimensional and three-dimensional comprehensive visualization browsing and model data query and display. A comprehensive geological information query and result output module comprises comprehensive superposition display of all stratum models, construction models, rock mass models, exploration lines and exploration line sections; a resource-environment information query, display and analysis module is used for realizing information query, display and analysis on fault wrinkles and the like in the practice area. And the field route selection module is used for providing coordinate information of each route and observation points. And the section cutting function and formation section display module is used for acquiring topographic data and assisting students to complete research of the disaster geology module. The method is simple to operate and high in interactivity, does not need network support, integrates practice data, and has a visualization function.

Description

technical field [0001] The invention relates to the field of virtual reality technology, computer technology, GIS remote sensing technology field and field practice teaching field. Specifically, it includes an integrated three-dimensional data acquisition and processing of sky, air and ground, three-dimensional geological modeling technology and virtual reality technology. Background technique [0002] In recent years, in order to adapt to the trend of integration, modernization and visualization of geological work, based on the vigorous development of virtual reality technology, computer technology, network technology and geographic information technology, how to effectively use computers to provide assistance for field geological teaching has become a major issue for the majority of geologists. Based on the development of these technologies, the computer virtual teaching system has emerged as the times require, and has become a powerful tool for field geological teaching. ...
