Abstract

The invention provides a scattering medium imaging method and system based on semi-definite optimization, and a medium, and the method comprises the steps: a scattering characteristic extraction stepof a scattering medium: estimating a scattering characteristic corresponding to the scattering medium through collecting a group of output speckle patterns corresponding to a known object image in thepresence of the scattering medium; and an image reconstruction step: after the scattering characteristic matrix corresponding to the scattering medium is estimated, according to a semi-definite optimization theory, solving a semi-definite programming problem to obtain a product of the image of the object to be reconstructed and Hermitian transposition thereof, and then extracting a characteristicvector corresponding to a maximum characteristic value of the product, thereby realizing scattering medium imaging. The method is used for improving the imaging precision and efficiency in the presence of a scattering medium, and the imaging precision is ensured while the efficiency is improved.

Description

technical field

[0001] The present invention relates to the technical field of scattering medium imaging, in particular, to a scattering medium imaging method, system and medium based on semidefinite optimization, especially to the fusion of transmission matrix theory and semidefinite optimization theory in the presence of scattering medium, In this way, the efficiency and imaging quality of scattering medium imaging can be improved. Background technique

[0002] Due to the scattering effect of the scattering medium, it is difficult for the traditional optical imaging system to effectively detect its internal targets. Imaging through scattering media has important scientific and application value, especially in the fields of biomedical imaging and remote sensing mapping. Many methods have been proposed in recent years to realize imaging of scattering media, such as the transfer matrix method. The transmission matrix method realizes the imaging of scattering media, and the ...
