Abstract

The present invention relates to a lens displacement optometry system based on pupil image acquisition using cloud technology, including an optometry terminal, a pupil image database and a central server; the first retrieval step includes screening and calibration parameters from the pupil image database The same collection parameters are used to obtain a first screening group composed of corresponding collection reference information, and the second retrieval step determines from the first screening group a collection data whose difference with the calibration data is within a preset range to obtain A second screening group is generated from the collection reference information, and the third screening step determines collection reference information from the second screening group and obtains observation parameters corresponding to the collection reference information to the corresponding optometry terminal. With this setting, firstly, 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 present invention relates to the field of optical optometry system, and more specifically, relates to a lens displacement optometry system based on pupil image acquisition 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 ...
