Problems solved by technology

[0003] The test process relies on doctors or inspectors. In the scene where the tested population is relatively concentrated (such as physical examination), the labor intensity of the doctor is too high, and it is easy to make mistakes in judgment and the efficiency is not high.

Embodiment 1

[0040] see figure 1 , the present embodiment discloses a vision detection method, comprising the following steps:

[0041] S1. Obtain the pre-stored electronic vision chart, and display the electronic vision chart on the display screen.

[0042] Specifically, the system can pre-store a plurality of different electronic eye charts, and randomly select one to display on the display screen for testing during testing.

[0043] S2. Select an optotype in the display screen, and mark the optotype in the display screen.

[0044] Specifically, the system randomly selects an optotype in the display screen as the target of the first test, and displays a detection mark under the optotype to be detected.

[0045] Marking is done by displaying a dot below the selected mark. The dot-shaped mark is more prominent, and it is also similar to the end of the pointer during manual inspection. It is easier to identify, and the tester can easily see the target to be inspected.

[0046] In additi...

Embodiment 2

[0069] This embodiment provides a visual inspection system, including:

[0070] The storage module is used for storing the electronic eye chart and detection data;

[0071] The processing module is used to select the electronic eye chart, select the visual mark to be detected, judge the obtained distance information and the size of the distance threshold, and execute the detection mechanism;

[0072] The display screen is used to display the electronic eye chart, and mark and display the selected optotype;

[0073] The distance sensor is used to obtain the distance information between the display screen and the quality inspection of the tester.

[0074] Preferably, it also includes a controller for inputting the answer result of the optotype.

[0075] In one example, the units in any of the above devices may be one or more integrated circuits configured to implement the above method, for example: one or more application specific integrated circuits (ASIC), or one or more A ...

Abstract

The invention relates to a vision detection system and detection method. The method comprises the following steps: obtaining a pre-stored electronic visual chart, and displaying the electronic visual chart in a display screen; selecting one sighting mark in the display screen, and marking the sighting mark in the display screen; obtaining a reply result of the tester to the marked sighting mark in the display screen; judging whether the reply result of the tester is the same as the selected sighting mark or not; and performing the next round of detection according to a detection mechanism until the detection is finished, and outputting a detection result. The vision testing efficiency can be improved, and the labor intensity of an operator is reduced. The system automatically judges the test result, improves the accuracy, and avoids manual judgment errors.

Description

technical field [0001] The present application relates to the technical field of vision detection, in particular to a vision detection system and a detection method thereof. Background technique [0002] During the vision testing process, the doctor or tester needs to stand on one side of the vision chart, use pointers such as a pointer to indicate the visual mark in the vision chart, and then turn his head to observe the tester's reply gesture or reply language. During the test, the doctor needs to keep looking back to observe the direction of the visual target on the current eye chart and the recognition of the visual target by the testee, and compare the two with each other before proceeding to the next test. [0003] The testing process relies on doctors or testing personnel. In scenarios where the tested population is relatively concentrated (such as physical examination), the labor intensity of doctors is too high, and it is easy to make mistakes in judgment and the ef...
