【摘要】：随着计算机技术的不断发展,可视化技术在各个领域的地位日益突出,现在已经成为一种趋势。将枯燥的数据转化更为直观的图形,使得人们更容易发现数据内部之间隐藏的规律,从而促进了生产,形成巨大的经济效益。尤其在地质勘探领域,地震数据的可视化更是一种前沿技术,是研究油藏构造和隐蔽性油气藏储层的重要手段。目前,地质专家迫切需要一套能充分利用地震信息、以直观图形对各种复杂数据场进行描述,并且拥有高精度的地震数据可视化软件。我们将基于上述设计一个基于地震数据三维图像系统。该系统以可视化的基本原理和基本过程为基础,使用Qt和Open GL技术,根据地震数据可视化系统的需求,实现了地震数据管理模块、数据解析模块、可视化模块、交互模块等四大模块。本文首先简单的对地震数据可视化系统的国内外发展现状、课题的研究意义进行阐述。其次,分析了可视化的基本原理和基本过程,并介绍了相关技术。然后,根据地震数据可视化系统的需求,对系统进行模块划分。接着,从地震数据入手,详细分析了地震数据SEGY的格式,给出了读取方法,并提出了砖块的存储方法来解决读取效率;详细介绍了波形绘制和颜色绘制的方法,以及纹理贴图技术的使用,并对涉及的算法进行了实现和分析。
[Abstract]:With the development of computer technology, visualization technology is becoming more and more important in various fields. Turning boring data into more intuitive graphics makes it easier for people to find hidden laws between data, thus promoting production and forming huge economic benefits. Especially in the field of geological exploration, the visualization of seismic data is a frontier technology, which is an important means to study reservoir structure and hidden reservoir. At present, geological experts urgently need a set of visualization software which can make full use of seismic information, describe all kinds of complex data fields with intuitionistic graph, and have high accuracy. Based on the above, we will design a three-dimensional image system based on seismic data. The system is based on the basic principle and process of visualization, using QT and Open GL technology, according to the requirements of seismic data visualization system, the seismic data management module, data analysis module, visualization module are realized. Interactive module and other four modules. In this paper, the development of seismic data visualization system at home and abroad and the significance of the research are briefly described. Secondly, the basic principle and process of visualization are analyzed, and the related technologies are introduced. Then, according to the requirements of seismic data visualization system, the system is divided into modules. Then, starting with seismic data, the format of seismic data SEGY is analyzed in detail, the method of reading is given, and the storage method of brick is put forward to solve the problem of reading efficiency, and the methods of waveform drawing and color drawing are introduced in detail. And the use of texture mapping technology, and the implementation and analysis of the algorithm involved.
