A lens displacement optometry system based on simulated light field using cloud technology

Abstract

The invention relates to a lens displacement optometry system based on a simulated light field using cloud technology, including an optometry terminal, a pupil image database, and a central server; the first retrieval step includes screening the first acquisition parameters and the second A calibration parameter is the same and a second acquisition parameter is the same as the second calibration parameter to acquire reference information to obtain a first screening group, and the second retrieval step determines from the first screening group a difference between the calibration data and the calibration data within The collection reference information corresponding to the collection data within the preset range to obtain the second screening group, the third screening step determines a collection reference information from the second screening group and obtains the observation parameters corresponding to the collection reference information to the corresponding On the optometry side, first of all, the database can be established by continuously inputting samples, and when the user needs optometry, the best optometry parameters can be obtained according to the cloud server, so that the optometry can be completed without the intervention of an optometrist.

Description

technical field [0001] The invention relates to the field of optical optometry systems, and more specifically relates to a lens displacement optometry system based on a simulated light field using cloud technology. Background technique [0002] Optometry is to check the convergence of light after it enters the eyeball. It takes the emmetropic eye state as the standard to measure the degree of vergence difference between the tested eye and the emmetropic eye. Since many people will be associated with glasses almost all their lives, optometry is currently one of the most basic and most commonly used but important tasks for optometry workers. Therefore, as far as the term optometry is concerned, in social life, Both ophthalmologists and ordinary people are very familiar with it. [0003] However, there are certain problems at present. Due to the different levels of optometrists, there will be differences in optometry results, which will affect the configuration of the user's a...
