Abstract

The invention discloses a terahertz image reconstruction method and device, a storage medium and a terminal. The method comprises the steps of obtaining time domain spectrum data of a target sample; converting the time domain spectrum data of the target sample into frequency domain data; inputting the frequency domain data into a terahertz image reconstruction model to obtain a target matrix; andobtaining a target image through the target matrix. According to the technical scheme, the terahertz image reconstruction model is simple, and the whole terahertz image reconstruction process is lowerin calculated amount and higher in efficiency while the terahertz image restoration effect is ensured.

Description

technical field [0001] The present invention relates to the technical field of terahertz images, in particular to a terahertz image reconstruction method, device, storage medium and terminal. Background technique [0002] In the existing technology (such as "Research on Terahertz Image Restoration and Detection Technology" - Song Zheyu, Changchun University of Science and Technology, Master's Degree Thesis, 2018), the deconvolution image restoration algorithm is disclosed and quoted, that is, using the physical characteristics of the terahertz beam The constructed point spread function restores the terahertz image and improves the image resolution; at the same time, by constructing the point spread function of different penetration depths in the sample, the effect of tomography on the sample image can also be achieved. Then, using terahertz imaging technology and deconvolution image restoration algorithm, the internal failure defects of various electronic packages and the wa...
