Embodiment

[0029] Example: such as figure 1 As shown, the present invention provides a technical solution, a digital holographic image reconstruction method based on deep learning, comprising the following steps:

[0030] S1. Collecting the original image, and then sampling the original image;

[0031] S2. After the sampling is completed, part of the data is discarded and compressed;

[0032] S3. After the compression is completed, the data is transmitted, and transmitted to the lower computer to be played;

[0033] S4, the lower computer decompresses the compressed package to which the data is transmitted;

[0034] S5. After the compression is completed, the image is restored and displayed.

[0035] According to the above technical solution, in step S1, the photoelectric image sensor is used to record the hologram, and the motion record is performed for the instantaneous state;

[0036] Use u(x, y) and r(x, y) to denote the object light wave and reference wave distribution on the ho...

Abstract

The invention discloses a digital holographic image reconstruction method based on deep learning, and the method comprises the following steps: S1, collecting an original image, and carrying out the sampling of the original image; s2, discarding part of data after sampling is completed, and compressing the data; s3, data transmission is performed after compression is completed, and the data is transmitted to a lower computer needing to be played; s4, the lower computer decompresses the compressed packet to which the data is transmitted; s5, after compression is completed, image restoration iscarried out, and the image is displayed; the structure is scientific and reasonable, safe and convenient use, a data acquisition card is subjected to A / D conversion and quantization post-processing, acomputer technology is introduced, and numerical calculation of a computer is utilized to simulate an object wave model function and an optical interference function, so that image data conversion isfacilitated, the conversion efficiency is improved, the transmission speed is reduced after compression, data is transmitted to a cloud end, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of digital holographic images, in particular to a digital holographic image reconstruction method based on deep learning. Background technique [0002] Digital holography is to use photoelectric sensing devices (such as CCD or CMOS) instead of dry plates to record holograms, then store the holograms in the computer, and use the computer to simulate the optical diffraction process to realize the holographic reproduction and processing of the recorded object. Digital holography and traditional optics Compared with holography, it has the advantages of low production cost, fast imaging speed, flexible recording and reproduction, etc. It combines mathematical technology with traditional optical holographic technology, uses CCD devices as holographic recording media, and mainly conducts digital holographic theory, methods, technologies and Research on the application of digital holography in particle fields, etc.,...
