Myopic diopter measuring system and method

Abstract

The invention relates to a myopia diopter measuring system. The system is characterized by comprising an image acquisition module, an image processing module and a calculation module. The image acquisition module is used for acquiring a face image of a consumer at the far point; the image processing module is used for acquiring the diameter of the iris on the far point face image; the calculationmodule is used for obtaining the myopic diopter. According to the system, the myopic diopter can be measured by a user or measured by an optical shop, the influence of subjective factors of the consumer during trial wearing of lenses in the traditional glasses preparation process can be avoided, and the glasses preparation process is simplified. Each consumer can clearly grasp changes in myopia and carry out eye care under the advice of diet and life provided by software.

Description

[0001] Statement of priority [0002] The technical solution of claim 1 of the present invention requires the content in the specific implementation plan of the description of the invention patent application with the application number 2017102931321 submitted to the Patent Office of the State Intellectual Property Office of China on April 28, 2017; [0003] The technical solution of claim 2 of the present invention claims the priority of the technical solution of claim 1 of the invention patent application with application number 2017102931321 submitted to the Patent Office of the State Intellectual Property Office of China on April 28, 2017; technical field [0004] The invention belongs to the technical field of myopia diopter detection, in particular to a measurement system and method for myopia diopter. Background technique [0005] When the eyeball is adjusted to be still, the focus of the parallel light from 5 meters away is just on the retina after the refraction of ...

Problems solved by technology

[0006] The most important thing in the spectacle preparation process is optometry, which uses the state of emmetropic eye as the standard to measure the degree of vergence difference between the subject eye and emmetropic eye. The commonly used equipment is optometry, which occupies a large part of clinical work. Compared with the low efficiency and complicated operation of the traditional retinoscopy method, the refractometer uses infrared, electronic, computer and other technical means to check the focus of the light after it enters the eyeball, and has the advantages of fast measurement speed and convenient use. In actual use, it is found that there are still some problems with the optometrist: 1. The optometrist is a special hardware, and it is necessary to hire a professional optometrist, who will operate step by step during the measurement and complete the measurement of the diopter of myopia. It is difficult for ordinary users to purchase it specially. The refractometer is expensive, and professional training on refraction operation cannot be obtained; 2. The accuracy of the refractor is affected by many factors, such as: poor coordination of the head and eyes of consumers, lack of concentration of gaze, and excessive nervousness of consumers, etc. 3. The refractometer can only measure the approximate diopter of myopia, and provide a reference for understanding the degree of refraction of consumers. In the end, the optometrist still has to base Consumers' subjective feelings to try on inserts to determine the appropriate degree
