Abstract

A calculation method for interval transit time. The method comprises: determining time domain boundaries of different types of wave signals in original signals of a pre-acquired target depth point (101); extracting target wave signals of the target depth point from the original signals of the target depth point according to the time domain boundaries of the different types of wave signals in the original signals of the target depth point (102); calculating frequency domain information and time domain information of the target wave signals (103); and calculating the interval transit time of the target wave signals at the target depth point by using the frequency domain information and the time domain information (104).
