Study On Key Technologies For Visualization Of The Borehole Geophysical Prospecting And The Software Implementaion

Currently, the focus of metal ore exploration is deep prospecting and borehole geophysical prospecting is a powerful tool to find the concealed orebody. Data processing is an important part in borehole geophysical prospecting. At present, there are a lot of softwares used to process a single method of borehole geophysical prospecting. But their functions are so simple that they can not process the borehole geophysical data systematically. Therefore, it is necessary to establish a comprehensive and visual processing platform to improve the efficiency of data processing and achieve the integration of borehole geophysical prospecting. By using the technology of three-dimensional visualization, software engineering, visual modeling and plug-in development, this paper studies the basic issues and the key technologies of the visualized and integrated processing platform of borehole geophysical prospecting.Through the research on visual graphics libraries, this paper selects Sharp GL as the basis for graphics library of the visualization platform. And then, combined with the requirements of the data processing, the related two-dimensional and three-dimensional components are designed and developed. According to the different requirements of the document format, the paper studies the secondary development of Map GIS and Auto CAD and achieves the function of non-destructive export of the result maps.Considering the geological models for different geological conditions, the paper achieves the visual modeling of 2.5D and 3D orebody model by using a combination of the profile design and three-dimensional display. By setting the two-dimensional workspace associated with the three-dimensional scene, the interactive function between two-dimensional plane and three-dimensional space is realized.This paper studies the serialization and de-serialization technologies, and completes the storage and transmission of the objects on the platform by using C#. During the part of drawing, the serialization plays a key role in saving and rebuilding the graphics card, graphics templates and orebody modeling. In addition, the serialization can also help finish the transfer of information of the objects between different processes.According to the diversity of the borehole geophysical data, this paper achieves a visualized and integrated processing platform based on layered architecture and plug-in technology. The system is divided into data, support and application layers, which reduces the coupling degree of the platform. In the system, plug-in technology is used and the corresponding interfaces are set up for the extended modules and tools. The processing program only needs to implement the interfaces, then it can be added to the system, which increases the scalability of the platform.It is a strong support for borehole geophysical prospecting to introduce the thought of visualization and integration. The platform makes the data processing expand from two-dimensional plane to three-dimensional space, which allows the users to observe the data from multiple views and provides a strong basis for finding concealed orebody underground. The platform leaves plug-in interfaces for the new borehole geophysical methods. It is hoped that the study is only a valuable role and more borehole geophysical methods will be added to the platform.
