摘要
地震剖面数据恢复 (或称图像矢量化 )的目的是利用图形识别等方法从旧地震剖面的扫描图像中拾取并复原地震道数据。波形搜索过程中 ,针对波形断点及地震道交叉等问题的处理策略进行了一些探讨 ,通过一种基于规则的控制模式 ,利用地震波形本身所具有的一些结构特点以及相邻地震道之间的纹理属性特征 ,引导波形搜索过程 ,使波形的拾取效果有了较大幅度的提高。
Restoration of seismic profile, or image vectorization, is a technique that tries to restore data of seismic traces from the scanned images of seismic profiles by using image recognition methods. After a discussion on how to deal with waveform interruption and intercrossing during searching, we presented a robust and efficient search control mechanism. The mechanism uses structure information and texture features between adjacent traces to guide the searching, which ensures the high quality of the restored data as shown by a comparison between original and restored data.
