Abstract

The invention discloses a vision detection device based on a VR scene, and the device comprises an obtaining module which is used for obtaining the vision information of a detection object after receiving a detection instruction, and determining the current detection degree based on the vision information; the labeling module is used for generating a vision detection table in the VR scene and randomly labeling a target detection symbol in the vision detection table based on the current detection degree; the recording module is used for receiving feedback information sent by the detection object and recording a matching result of the feedback information and the target detection symbol; and the repeating module is used for marking the next target detection symbol based on the matching result, and repeating the step of receiving the feedback information sent by the detection object until the number of times of repeating is greater than a preset number of times, and generating a vision detection result based on each matching result. According to the method and the device, vision detection is performed by displaying the vision detection table in the VR scene, so that the vision detection meeting the standard can be performed in any environment and place, and the accuracy of a vision detection result is ensured.

Description

technical field [0001] The present application relates to the field of VR technology, and in particular, to a vision detection device based on a VR scene. Background technique [0002] Eyesight detection is generally to hang an eye chart indoors, and maintain a sufficient distance between the test object and the eye chart by means of mirror reflection, etc., and the doctor randomly points to a certain character in the eye chart for detection. Such a detection method has high requirements on indoor space, and requires sufficient space or a reasonable layout to ensure the distance between the detection object and the eye chart. However, in addition to vision testing in hospitals, some companies or schools also regularly conduct health testing on employees or students, including vision testing. Since the location for health testing is not fixed, it cannot be guaranteed that each test has suitable conditions for vision testing, so that the final vision testing environment does ...
