AI Technical Summary

Technical Problem

The mirror adjustment method of the existing eye chart requires manual operation, resulting in slow adjustment speed, low precision and lack of intelligence, which affects the user experience.

Method used

By acquiring an image of the human eye being measured and utilizing the reflective element to rotate around the axis, the reflector angle is automatically adjusted according to the position of the human eye in the image, so that the outgoing light accurately enters the human eye, achieving alignment without manual adjustment.

Benefits of technology

It realizes intelligent automatic alignment of the eye chart, improves the adjustment speed and accuracy, and enhances the user experience.

Abstract

The application discloses an alignment adjustment method and system, which is applied to a device including a reflecting element, the reflecting element reflects incident light to form outgoing light which is incident to a measured human eye, and the reflecting element can rotate around a rotation shaft. The method comprises the following steps: acquiring an image of the measured human eye when the reflecting element is in an initial state to obtain a first image, the vertical direction of the image is perpendicular to the rotation shaft when the image is acquired; obtaining a vertical distance from the measured human eye to a reference vertical position in the first image, obtaining a first angle of a current actual position of the measured human eye relative to a preset actual position according to the vertical distance, and rotating the reflecting element from the initial state around the rotation shaft according to the first angle to make the outgoing light formed by the reflecting element incident to the measured human eye. The application can make the outgoing light formed by the reflecting element incident to the measured human eye by acquiring the image of the measured human eye and rotating the reflecting element according to the position of the measured human eye in the obtained image, so that the outgoing light is aligned with the measured human eye, and the application is more convenient and intelligent without manual adjustment.
