First arrival wave automatic pickup method and device

The embodiment of the invention provides a first arrival wave automatic pickup method and device. The method comprises the following steps: cutting first arrival attribute data in a first arrival timewindow in to-be-picked shot gather data according to a preset proportion to obtain a first arrival attribute data set matrix; detecting the first arrival attribute data set matrix according to a preset semantic network model to obtain a corresponding first arrival detection result data set matrix; and obtaining a first arrival result data set matrix consistent with the original shot set first arrival time window data according to the number information and the position information of the first arrival detection result data set matrix, and determining first arrival wave position information according to a prediction probability value in the first arrival result data set matrix and a preset threshold. The method and the device can accurately and efficiently pick up the first arrival waves of the mass seismic data w
