Embodiment 1

[0027] This embodiment provides an intelligent vision detection system based on VR technology and gesture recognition, including:

[0028] VR equipment: used to virtualize the vision chart detection scene, in which there are virtual vision charts and virtual vision inspectors, and the visual size and visual distance of the vision chart meet the requirements for vision chart detection; The virtual vision tester instructs the subject to identify each row of visual marks on the eye chart from top to bottom, and voice prompts the subject to make corresponding gestures in front of the camera module according to the direction of the recognized visual mark; According to the comparison result of the comparison module, it is judged whether the visual mark detection of the current row has passed. If it passes, the virtual vision tester in the vision chart detection scene will start the detection of the next line of visual mark. If it fails, it will be obtained according to the set rules....

Embodiment 2

[0034] This embodiment provides a method for using the system described in Embodiment 1, and the specific process is as follows:

[0035] The subject first uses a blindfold or one hand to cover the other eye except the tested eye (if both eyes need to be tested, the right eye should be tested first, then the left eye), and then put on the VR device ;

[0036] The VR device virtualizes an eye chart detection scene, in which there are virtual vision charts and virtual vision inspectors, and the visual size and visual distance of the vision chart meet the requirements of the vision chart detection; in the vision chart detection scene, the virtual vision test The staff instructs each row of visual marks on the eye chart from top to bottom for the subject to identify, and voice prompts the subject to make corresponding gestures in front of the camera module according to the direction of the identified visual mark;

[0037] The camera module transmits the acquired gesture image of ...

Abstract

The invention provides an intelligent vision detection system and method based on a VR technology and gesture recognition. The system comprises VR equipment, a camera module, a gesture recognition module and a comparison module. By combining the VR technology and the gesture recognition technology, a visual chart detection scene can be virtualized, the actual space does not need to be occupied, and the method and system can be implemented at any place at any time, and are high in efficiency and timely. In addition, when the method and system are used for vision detection, the detection environment is stable, the method and system are not influenced by surrounding changes, privacy is achieved, manpower is saved, operation and scoring by a specially-assigned person are not needed, a detection result is automatically obtained, and the method and system are more scientific and objective.

Description

technical field [0001] The invention relates to the technical field of vision detection, in particular to an intelligent vision detection system and method based on VR technology and gesture recognition. Background technique [0002] With the development of society and the advancement of science and technology, people have more and more ways to obtain information, and the amount of information they read every day has also doubled. Excessive eye use leads to a general decline in vision. The proportion of people wearing glasses is getting higher and higher, and the age is getting younger. At present, vision testing is generally performed by professional optometrists in hospitals or other vision testing institutions. For people who want to pay attention to their vision, it is time-consuming and not timely. [0003] At present, the most common method of visual acuity testing is through the traditional eye chart. This testing method has the following disadvantages: [0004] 1. ...
