And S2, serializing the seismic data to obtain a binary data file by referring to the first format definition file.
Specifically, the method for obtaining a binary data file by serializing seismic data with reference to a first format definition file comprises the following steps: and writing the array length and the array data of the seismic data into a binary data file in sequence by referring to the first format definition file.
