Design And Implementation Of Eye Image Acquisition Device Based On Android Platform

At present,the application research in the field of active health ophthalmology is relatively blank,and the products have not formed their characteristics and clear main development directions.This paper designs and implements on the basis of referring to ophthalmological image medical devices and active health innovation products and patents in this field.An Android-based acquisition device for eye cracks and eye images around the eyes,including hardware and software for the host computer terminal,which can be used as an active health product for self-monitoring and management of eye health,as well as for eye Provide data support for early disease screening and early warning of the Ministry of Diseases.For the realization of this device,the following work is mainly completed:(1)Determine the hardware performance index and software function requirements of the eye image acquisition device: The device needs to meet the hardware performance index and software function requirements based on the standards of relevant medical devices in the field of eye image inspection and the use scenario requirements of this device.(2)The design and implementation of the hardware and structure of the eye image acquisition device: According to the hardware performance requirements of the eye image acquisition device,the high-definition camera module based on the CMOS image sensor is selected,and the liquid lens technology is used as the basis for hardware focusing.Using Zmax optical simulation software to design the front combination lens;using Altium Designer circuit design software as an auxiliary design and realizing the liquid lens driving circuit and lighting circuit;based on the relevant size requirements proposed by ergonomics,using Proe 3D model design software design And realized a portable hardware mechanical structure.(3)Design and implementation of the terminal software function of the eye image acquisition device: According to the software function requirements of the eye image acquisition device,the software and hardware interaction of the eye image acquisition device is completed under the development environment of the Android studio platform,and realized on this basis It includes the basic functions of image acquisition and auxiliary functions such as image contrast,brightness adjustment,automatic white balance,and focal length adjustment.(4)Hardware performance and software function test of the eye image acquisition device: select a representative Android smart device as the upper computer terminal,test the hardware performance and related software functions,and verify whether it meets the design standards.The eye image acquisition device based on the Android platform developed by this subject can be effectively applied to most Android smart devices.The software operation interface is concise and clear.The hardware adopts a portable structure and is simple to use,making up for the cumbersome operation of general eye image detection medical devices.3.The disadvantages of solidified usage scenarios and high prices are more conducive to popularization to grassroots users,and can be applied to the field of active health,and have practical reference significance for the development and iteration of products in the subsequent fields.
