In seismic data processing, the accurate firstbreaktime 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 firstbreaktime 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 firstbreaktime is discussed in this paper, which based on the specialty of firstbreaktime.
