摘要
讨论了地震图中地震波形的自动提取方法,提出了一种适用性较强的水平校正和水平消除算法,以及一种利用峰值与零点进行波形校正的算法,归纳了波形提取中的各种波形模式并给出了智能化的波形搜索规则。
In this paper, discussing the method in auto\|extracting wave from seismic record, a robust horizontal correcting and a horizontal line deleting algorithms are presented. The authors also produced a variational Hough transform used for wave\|correcting, and concluded the wave model for wave extracting. After that,the rules in intellective wave\|searching method are presented.
