基于Qt的共聚焦点技术地震资料处理系统研发
|
摘要
从软件编程的角度分析了共聚焦点(CFP)技术,重点总结了成像技术和成像算法步骤,给出了基于CFP技术的地震资料处理流程。在充分利用Linux操作系统环境的稳定、高效特性的基础上,结合跨平台的C++图形用户界面库Qt,使用C/C++和Fortran语言混合编程、多线程和面向对象等技术,开发了基于CFP技术的地震资料处理系统。该处理系统的研发为其它地震资料处理软件的研发提供了一套解决方案。
CFP(common focus point)technology is analyzed from software program aspect,especially imaging technology and processing algorithm is summarized,and a seismic data processing flow is given based on CFP technology.The processing system is developed by utilizing the stable and high efficient features of Linux operating system,combined with a cross-platform Qt graphical user interface software library,written by mixed programming languages including C/C++and FORTRAN,and designed by the multi-tread and object-oriented programming,etc.The processing system provides a solution for the development of other seismic data processing software.
