Intelligent vision testing method, device and system

Abstract

The invention relates to the field of intelligent vision testing, in particular to an intelligent vision testing method, device and system, and the method comprises the steps: obtaining the position information and height data of a testee; adjusting a sighting mark image displayed on the vision testing device according to the position information and the height data; identifying a test indication mode of the testee; and controlling the vision testing device according to the identification result to complete the vision testing process. By means of the intelligent vision testing method, device and system, the whole vision testing process can be completed more intelligently.

Description

technical field [0001] The invention relates to the field of intelligent vision testing, in particular to a method, device and system for intelligent vision testing. Background technique [0002] At present, the existing intelligent vision test method requires that the distance between the examiner and the device is fixed and cannot be adjusted at will; the uncertainty of ambient light has an impact on the test results; due to the fixed position and direction of the detection target, the detection mode is single and there is detection memory Defects of cheating; the detection work needs to be completed by the cooperation of the inspector and the inspected, the degree of intelligence is low, the output of the inspection results is still the traditional paper record output, and there is no defect in the digital output of the results; the installation height of the eye chart is fixed, but The heights of the testers are different, and it is impossible to ensure that the height o...

[0002] At present, the existing intelligent vision test method requires that the distance between the examiner and the device is fixed and cannot be adjusted at will; the uncertainty of ambient light has an impact on the test results; due to the fixed position and direction of the detection target, the detection mode is single and there is detection memory Defects of cheating; the detection work needs to be completed by the cooperation of the inspector and the inspected, the degree of intelligence is low, the output of the inspection results is still the traditional paper record output, and there is no defect in the digital output of the results; the installation height of the eye chart is fixed, but The heights of the testers are different, and it is impossible to ensure that the height of the eyes of the testee is parallel to the height of line 1.0 of the visual acuity chart, which cannot meet the test requirements; the test efficiency is low, because the testers cannot predict the visual ability of the testee, they need to follow from high to low or from high to low The order of low to high is tested sequentially, and the test efficiency is low; the data of intelligent vision detection objects needs to be processed manually, and background processing and tracking cannot be performed
