Summary:The invention discloses a seismic data reconstruction method based on VD-Seislet transformation and an acceleration Bregman method, and particularly relates to the technical field of geophysical exploration. According to a preset seismic data sampling mode, an original seismic signal collected in the field is obtained, an original seismic data matrix is obtained, the original seismic data matrix is preprocessed based on a VD-Seislet transformation method, and through denoising processing, local slope conversion and sparse transformation, the seismic data is obtained. After the seismic data matrix and the sparse transformation matrix after denoising processing are obtained, the seismic data matrix is reconstructed by using the sparse transformation matrix based on an accelerated Bregman algorithm, reconstructed seismic data are obtained, and the reconstructed seismic data matrix is compared with the original seismic data matrix; and evaluating the construction quality of the reconstructed seismic data matrix b
