【摘要】 在地震勘探过程中,同相轴的识别和追踪是一个很重要的环节。为了提高信噪比和分辨率,便于进行地震资料解释工作,利用图像边缘检测技术来识别、追踪地震反射波同相轴。分别利用Roberts、So-bel、Prewitt、Log以及Canny算子来检测地震剖面同相轴边缘,再经过提取包络线中轴、斑点去噪等处理得到了最终的同相轴追踪结果,并发现利用LOG算子和Canny算子追踪的同相轴比较完整、丢失现象比较少且连续性好。更多还原

【Abstract】 In the course of seismic exploration,auto identifying and tracking the syncphase axis is a very important part.In order to improve the signal-to-noise ratio and resolution and work for seismic data interpretation,use edge detection technology to identify and track the axis.We use Roberts,Sobel,Prewitt,Log and Canny operator to detect the edge of the axis,and then after that we use the median axis of the surround line of the higher gray as the seismic syncphase axis and then eliminating fleck yawp,we get the final result.After the work above finished we found the merits of the LOG and Canny operators’result are more integrated and consecutive.更多还原
