Embodiment 1

[0060] see figure 1 , figure 1 It is a schematic flow chart of the visual fatigue detection method disclosed in Embodiment 1 of the present invention; figure 1 As shown, the visual fatigue detection method may include:

[0061] 101. The electronic device acquires a facial image of a user.

[0062] In the embodiment of the present invention, when the electronic device is being used, the camera may periodically take images of the user's face.

[0063] 102. The electronic device recognizes the face image to obtain recognition parameters, and the recognition parameters include at least a first distance between the hand and the eyes when the hands are in front of the eyes, a first duration when the hands and the eyes are maintained at the first distance, and A second duration of the hand movement, where the second duration is obtained according to a time period after the first duration.

[0064] It can be understood that when the user has visual fatigue, the eyes will experienc...

Embodiment 2

[0080] see figure 2 , figure 2 It is a schematic flow chart of the visual fatigue detection method disclosed in Embodiment 2 of the present invention; figure 2 As shown, the visual fatigue detection method may include:

[0081] 201. The electronic device acquires a facial image of a user.

[0082] 202. The electronic device recognizes the face image to obtain recognition parameters, the recognition parameters at least include a first distance between the hand and the eyes when the hands are in front of the eyes, a first duration when the hands and the eyes are maintained at the first distance, and A second duration of the hand movement, where the second duration is obtained according to a time period after the first duration.

[0083] 203. If the first distance is less than or equal to the distance threshold included in the learning parameter, and the first duration is not less than the static duration included in the learning parameter, the electronic device determines ...

Embodiment 3

[0105] see image 3 , image 3 It is a schematic structural diagram of an electronic device disclosed in Embodiment 1 of the present invention; image 3 As shown, the electronic equipment may include:

[0106] An acquisition module 310, configured to acquire a user's facial image;

[0107] A parameter identification module 320, configured to identify the facial image to obtain identification parameters, the identification parameters at least include a first distance between the hand and the eyes when the hand is in front of the eyes, and a first duration when the hand and the eyes are maintained at the first distance Duration, and the second duration of hand movement, the second duration is obtained according to the time period after the first duration;

[0108] Determination module 330, for if the first distance is less than or equal to the distance threshold included in the learning parameter, the first duration matches the static duration included in the learning paramet...

Abstract

The embodiment of the invention discloses a visual fatigue detection method and electronic equipment. The method comprises the following steps: a face image of a user is acquired; the face image is recognized to obtain recognition parameters, the recognition parameters at least comprise a first distance between the hand and the eyes when the hand is located in front of the eyes, a first duration when the hand and the eyes are maintained at the first distance and a second duration when the hand moves, and the second duration is obtained according to a time period after the first duration; if the first distance is smaller than or equal to a distance threshold value contained in the learning parameters, the first duration is not smaller than a static duration contained in the learning parameters, and the second duration is not smaller than a motion duration contained in the learning parameters, it is determined that the user is in an asthenopia state; the user asthenopia state can be accurately detected, and the user eyes are protected.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a visual fatigue detection method and electronic equipment. Background technique [0002] With the improvement of people's living standards, more and more children can use some electronic devices for extracurricular learning and entertainment, such as tutoring machines and tablet computers. However, children's self-control ability is relatively poor, and prolonged use of electronic devices will cause children's visual fatigue and affect their visual development. Therefore, how to accurately detect whether the user is visually fatigued when children use electronic devices to reduce the risk of visual fatigue It is one of the directions that those skilled in the art have been constantly striving for. Contents of the invention [0003] The embodiment of the invention discloses a visual fatigue detection method and an electronic device, which are used for visual fatig...
