Summary:The invention relates to a three-component three-dimensional seismic data reconstruction method and device, and the method comprises the steps: carrying out the vector joint representation of three-component data in a time domain through employing a quaternion, and obtaining a time domain quaternion signal; performing quaternion Fourier transform on the time variable, and transforming the time domain quaternion signal into a frequency domain to obtain a frequency domain quaternion signal; on the basis of the frequency domain quaternion signal, performing iterative reconstruction on the positive frequency slice data and the negative frequency slice data by using a quaternion matrix decomposition rank reduction algorithm to obtain a reconstructed frequency domain quaternion signal; and performing quaternion inverse Fourier transform about a frequency variable on the reconstructed frequency domain quaternion data to finally obtain quaternion reconstruction data of a time domain, extracting time domain reconstruc
