The method comprises the following steps: firstly, researching the advantages and disadvantages of a Slicer Dicer three-dimensional visual formation graph; analyzing data structure characteristics of the readable file of the software, determining a three-dimensional mapping mode of the software, and converting the three-dimensional inversion data into readable data of the software through programming, thereby realizing a three-dimensional visual mapping technology of the mine geophysical inversion data, and making slice maps of different layers so as to meet requirements of engineering personnel; the method is simple, is convenient to operate, can directly read data in various formats, realizes three-dimensional visualization of inversion data of a mine direct current method, and has a very good practical application value.

Description

technical field [0001] The invention belongs to the technical field of mine geophysical exploration, and relates to a three-dimensional visualization method of mine direct current method, in particular to a three-dimensional visualization method of mine direct current method data volume. Background technique [0002] After the mine geophysical data collection is completed, after data processing and data inversion, the 3D inversion data body is generally displayed with the help of 3D visualization software. Among them, the commonly used mapping software for direct current method inversion data includes Surfer software, Voxler software, Matlab's own 3D visualization Slice function and other software, but Surfer software is generally 2D and is rarely used for 3D visualization. Both Voxler software and Surfer software are products of American Golden Software Company. In 2006, the company launched Voxler software. This software can make three-dimensional visualization maps with k...

Problems solved by technology

[0006] (1) Study the advantages and disadvantages of Slicer Dicer 3D visualization mapping: use the Slicer Dicer software to make the inversion data in a fixed format into a 3D electrical data volume, and make slices in different directions according to the distribution of the 3D electrical data volume. Slices include horizontal slices (slices in the X direction), vertical slices (slices in the Y direction or Z direction) and layered slices along a certain angle. Using slice technology, the distribution of geological bodies can be visually and intuitively observed to meet the needs of engineers , but the determination of the software can only read a fixed format (for example, the reading format of RES3D is a GM format file), and it cannot be directly applied to most inversion data, especially for some MATLAB software data structures that cannot be directly read
