Description

technical field [0001] The invention belongs to the technical field of collaborative visualization and modeling based on multi-source multi-parameter gravity and magnetic data of geophysics, and in particular relates to a collaborative visualization and modeling system and method for multi-source multi-parameter gravity and magnetic data. Background technique [0002] For a long time, gravity and magnetic method interpreters are more inclined to the interpretation process of human-computer interaction. Interpreters often use simple and regular shapes to simulate complex geological bodies. Among them, the human-computer interaction modeling and interpretation method and system of gravity and magnetic anomalies in section (2D) are more suitable. Sophisticated and common. In the process of 3D gravity and magnetic interpretation, it is necessary to continuously edit and modify the geological body model, so the interactive modeling method becomes the key issue of the system. In ...

AI Technical Summary

Problems solved by technology

[0005] 1. In terms of 3D visualization expression, there is a lack of perfect 3D modeling and scene control, rich model information extraction and model integration capabilities;

[0006] 2. The geophysical influence factors are not considered in the process of establishing the geological model. Most of them are two-dimensional profile data human-computer interaction modeling schemes, which integrate three-dimensional geological elements such as faults, layers, geological bodies and geophysical elements. Borehole data, seismic data, and physical property data , Collaborative modeling and visualization methods for geophysical interpretation data are rare;

[0007] 3. Existing open source systems lack unified management of multi-source and multi-type data and method and technology support, lack of relatively complete 3D scene control and interpretation data interaction; most do not support collaborative visualization of 2D and 3D observation and interpretation data, and the response speed is slow Slow, making it inconvenient for interpreters to use
