In seismic data processing, the accurate first break time is the key parameter to solve static correction problems of complex surface.
在地震资料处理中,正确的初至时间,是解决复杂地表静校正问题所需的关键参数。
It is based on the least square of the difference between the real reflection first break time and corresponding modeled ray-tracing travel time.
此法以反射地震资料中的观测初至旅行时与模型射线追踪旅行时之差的最小平方法为基础。
The digital image processing such as edge detection and boundary tracing to pick up the first break time is discussed in this paper, which based on the specialty of first break time.
根据初至波特点,基于数字图像处理技术,提出了应用边缘检测和边缘追踪技术进行初至波自动拾取的方法。该方法的实现过程为:①对地震记录做单道归一化处理;
