A Research Of Visualization Techniques In SYT Natural Electromagnetic Waves Exploration

Geological bodies are large and complex three-dimensional space, which contain thecoal bed in them. How to find out the coal bed position accurately, it will become a keywhich can protect the coal production safety and highly efficient. Three-dimensionalgeological model can describe the information of coal bed position accurately which inthe two-dimensional chart. They also can show the position of coal bed in theThree-dimensional space accurately. Now, three-dimensional geological model moreand more use in the Design and implementation of engineering project, because theycan provide more intuitive geological body to geological and mining experts. Geologyand mining experts can tell the results of this platform to someone who not haveKnowledge of geological field easily, they also can communicate with other expertswho can make decisions and reduce construction risk.The main of this paper is to develop a three-dimensional visualization system of SYTnatural electromagnetic exploration equipment with VTK. First, analyze the data ofSYT natural electromagnetic exploration equipment to make sure can use it build thegeological model by Delaunay triangulation.Next, discuss the spatial interpolationalgorithm, and proposed a kriging algorithm which can contain the information of nocoal zone, the fall of columns, and other special geological conditions caused byabnormal data. Finally, develop the three-dimensional visualization system of SYTnatural electromagnetic exploration equipment by VC6.0platform, and show how touse system by the data of dingxin Coal Co. By example, showing the application of3D visualization system in the data analysis, data processing, three-dimensional modelsshow field...
