Abstract

The embodiment of the invention discloses a compressed sensing imaging method, apparatus, device and system and a storage medium. The method employs an image compression coding device configured to perform compression, coding and sampling of a target image, a sampling controller and an image reconstruction calculator. The image compression coding device comprises a one-dimensional coding aperturetemplate and a linear array image detector, and the one-dimensional coding aperture template corresponds to the linear array image detector; the sampling controller controls drive of the one-dimensional coding aperture template and the linear array image detector to perform coding sampling and sends the obtained sampling data to the image reconstruction calculator; and the image reconstruction calculator is configured to perform single iteration of the reconstructed integrated sparse coefficient matrix through adoption of each dimensions of data based on the sampling data to obtain a recoveredtarget image. The compressed sensing imaging method, apparatus, device and system and the storage medium simplify the coding process, reduce the cost, eliminate the blocking effect of the block compression sensing system, obviously improve the image quality and achieve higher imaging quality with a lower hardware cost.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computational imaging, and in particular, relate to a compressed sensing imaging method, device, device, system, and computer-readable storage medium. Background technique [0002] With the rapid development of signal processing technology, in order to break through the limitations of the traditional Nyquist sampling theorem, the application of compressive sensing theory was born. The theory points out that if a signal is sparse in a certain transform domain, the original signal can be accurately recovered with high probability through a small number of low-dimensional projection values ​​of the signal in other uncorrelated transform domains. The requirements for signal acquisition equipment and the amount of data are greatly reduced, subverting the traditional one-to-one imaging method, and widely used in space remote sensing, medical imaging, radar imaging, data compression and oth...
