Problems solved by technology

[0005] (1) Existing multi-spectral fundus imaging systems are bulky and cumbersome, and poor in portability
[0006] (2) The existing multi-spectral fundus imaging system has high equipment cost
Its expensive equipment costs lead to high diagnostic costs for patients, and is not conducive to the promotion of this equipment in small and medium hospitals
[0007] (3) The existing multi-spectral fundus imaging system equipment has low openness, which is not conducive to artificial intelligence diagnosis based on the Internet and big data

Embodiment 1

[0030] Optical path design of the present invention such as figure 1 As shown, mobile multispectral imaging can be realized. It is mainly composed of a set of lighting module and fundus image acquisition module. Among them, the lighting module uses the built-in flash LED of the smart terminal as the light source. The light is converted into parallel light through lens A, and then filtered by different filters on the filter wheel to generate light of selected wavelengths. Subsequently, the light of a specific wavelength passes through a diffuser, a linear polarizer A, a mirror and a beam splitter placed at an angle of 45°, and then is focused to the retina through a lens B. The light reflected by the retina passes through lens B, beam splitter, linear polarizer B and lens C to amplify the retinal image and image it on the smart terminal camera. Wherein, the combination of linear polarizer A and linear polarizer B is used to eliminate reflected light generated by specular refl...

Abstract

The invention relates to the field of medical health, and discloses a multispectral fundus imaging device and method based on an intelligent terminal. The device includes a lighting module, a fundus image acquisition module and a data processing module; the lighting module uses the flash LED that comes with the smart terminal to provide retinal illumination through different filters; the fundus image acquisition module uses the smart terminal camera to acquire images. The collected color images at specific wavelengths within a certain wavelength range are collected through spectral reconstruction from RGB values ​​to spectral values ​​to complete the collection of fundus multispectral images. The collected fundus multispectral images will be uploaded to the Internet cloud through the data processing module. After artificial intelligence diagnosis is performed in the cloud, the results will be fed back to the smart terminal. Improve the convenience of the multispectral fundus imaging system; reduce equipment costs; promote medical informatization and achieve diagnostic accuracy close to or exceeding that of doctors, which will help assist patients in self-diagnosis, improve work efficiency, and rationally allocate medical resources.

Description

technical field [0001] The invention relates to the field of medical care and health, in particular to an intelligent terminal-based multispectral fundus imaging device and method. Background technique [0002] With the improvement of people's living standards and the arrival of the country's aging population, mobile health, family-style, and personal portable monitoring medical care are becoming more and more popular. The human retina is one of the observation targets with important clinical significance. By observing changes in the retina, the diagnosis of fundus diseases and even cardiovascular and cerebrovascular diseases can be realized. [0003] Because different light passes through the fundus in different depths and is absorbed by different substances, it is possible to obtain images of different layers of the fundus and richer biomedical information by selecting light of appropriate wavelengths. However, most of the existing multi-spectral fundus imaging systems u...
