The invention discloses a compressed sensing-based frequency domain multi-resolution imaging method. The method comprises the following steps: S01, generating an image sensing matrix and transmittingthe image sensing matrix to an image sampling module for performing image sampling by adopting a compressed sensing matrix module; S02, generating a spectrum sensing matrix and transmitting the spectrum sensing matrix to a spectrum sampling module for performing spectrum sampling to obtain the spectrum sampling data Sp of each sampling pixel point by adopting the compressed sensing matrix module;S03, performing spectrum data reconstructing based on the spectrum sampling data Sp of each sampling pixel point to obtain a spectrum curve Sp.r of the corresponding sampling pixel point; S04, determining the spectrum resolution bm for reconstructing an image, determining the spectrum data Sp.r(bm) under the spectrum resolution bm in the spectrum curve of each sampling pixel point, and reconstructing to obtain a spectrum i
