Lens displacement optometry system based on pupil image acquisition by adopting cloud technology

Abstract

The invention relates to a lens displacement optometry system based on pupil image acquisition by adopting cloud technology, which comprises an optometry end, a pupil image database and a central server; a first retrieval step comprises: filtering acquisition parameters which are the same as calibration parameters from the pupil image database to obtain a first screening group composed of corresponding acquisition reference information; a second retrieval step comprises: determining an acquisition data within a preset range of a difference value of a calibration data from the first screening group so as to obtain a second screening group generated by the acquisition reference information; a third screening step comprises: determining the acquisition reference information from the second screening group and acquiring observation parameters corresponding to the acquisition reference information to the corresponding optometry end. According to the arrangement, firstly, a database can be established by continuously inputting samples; when a user needs to perform optometry, the optimal optometry parameters can be obtained according to the cloud server, so that optometry can be completedwithout 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 ...
