Astigmatism diopter measurement system and method

Abstract

The invention relates to an astigmatism diopter measurement system. An image processing module calls compound myopic astigmatism face image obtaining process, compound hyperopic astigmatism face imageobtaining process or simple astigmatism face image obtaining process according to states of one naked eye of a consumer respectively, obtains a starting point face image and a destination face imagethrough a camera and calculates starting point diopter and destination diopter according to the two face images, wherein the difference of the two diopters is astigmatism diopter. In the astigmatism diopter analysis measurement system, the astigmatism diopter result can be measured by a user himself / herself and can be also measured in an optical store, the influence of subjective factors of consumers during eyeglass insertion for the consumers to try on in traditional spectacle prescribing process is avoided, the spectacle prescribing process is simplified, and each consumer can clearly masterthe change of myopia degree and perform eye health care according to the diet and life suggestions and the like provided by software.

Problems solved by technology

[0006] The simplest and most practical way to correct astigmatism is to wear glasses, and the most important thing in the preparation process is optometry. The commonly used equipment is optometry, which occupies a very important position in clinical work. And other technical means to check the focus of light after it enters the eyeball has the advantages of fast measurement speed and convenient use. However, in actual use, it is found that there are still some problems with the refractor: 1. The refractor is a special hardware, and it is necessary to hire a professional optometrist. , by operating step by step during the measurement to complete the measurement of diopter, it is difficult for ordinary users to purchase expensive refractometers, and they cannot obtain professional training on refraction operations; 2. The accuracy of refractors is affected by many factors , For example: poor coordination of the head and eyes of consumers, lack of concentration of gaze, and excessive nervousness of consumers will cause large errors, so it is inappropriate to use the optometry as the only basis for glasses preparation; 3. The optometry can only measure The general situation of the diopter provides a reference for understanding the degree of refraction of the consumer. The optometrist still needs to try on the insert according to the subjective feeling of the consumer to determine the appropriate degree.
