【摘要】 随着我国深部探测计划的实施,近年来在中国大陆地区实施了多条深地震反射剖面,获得了大量揭示地壳上地幔精细结构的宝贵资料.为了更充分地挖掘这些资料中所包含的深部构造信息,本文在研究和总结前人工作的基础上,提出一种快速识别深地震反射剖面构造格架的方法.该方法通过数据预处理、强振幅提取、中值滤波、对象识别、连续性计算和连续性滤波实现对深地震反射剖面构造格架识别.同时,该方法还可通过对象倾角计算对复杂区域进行属性分析.更多还原

【Abstract】 With the execution of the SINOPROBE project,several deep seismic reflection profiles were recorded in the past five years.And plenty of valuable seismic data which reveal the fine structure of crust and uppermost mantle was collected.In order to obtain more deep structure information from those profiles,this paper developed a new method to recognize seismic events automatically.Based on the digital image processing technique and pattern recognition theory,the method is composed of the following modules: data pretreatment,amplitude analysis,median filtering,object recognition,continuity calculating and continuity filtering.Besides to recognize structure information from deep seismic profiles,this method is also used to analyze the seismic events angle distribution of structural complex areas.更多还原
