This invention discloses a fiber optic seismic record reconstruction method based on CVAE and detector constraints, belonging to the field of geophysical exploration and signal processing technology. It utilizes discretely distributed high-precision seismometers as anchor points to segment distributed acoustic wave sensing fiber optic acquisition data. A pre-trained reconstruction model, centered on a conditional variational autoencoder (CVAE), is constructed to obtain general mapping characteristics for converting fiber optic acquisition data to high-fidelity seismic detector acquisition data. The fiber optic acquisition data is preprocessed to align its modes with those of the seismic detector acquisition data. Each data segment and the seismic detector acquisition data at its two end anchor points are used as input constraints. Leveraging the continuous evolution characteristics of the CVAE latent space and combining real-time double-ended strong boundary constraints, a high-fidelity seismic record with high sampling density is output. This effectively solves the technical challenge of integrating high-density observation with high-quality processing systems, thereby improving exploration accuracy.
