Embodiment Construction

[0013] The invention predetermines the safety threshold of the distance between the two eyes in the face image, monitors the user in real time with a camera when the user reads the screen, and collects the user's face image. Then, compare the actual distance between the two eyes in the collected face image with the set safety threshold, determine whether the user is too close to the screen according to the comparison result, and remind the user to adjust the viewing distance if too close.

[0014] figure 1 It is a flow chart of the monitoring method for realizing the visual distance from the human eye to the screen in the present invention, and the method includes:

[0015] Step 101: Preset the safety threshold of the distance between the two eyes in the face image, the safety threshold is determined according to the viewing distance from the human eye to the screen when the camera captures the face image.

[0016] Step 102: Perform image sampling on the user's face according...

Abstract

The invention provides a monitoring method for visibility range from eyes to a screen. The monitoring method includes presetting a safety threshold value of distance between two eyes of a human face image, performing image sampling according to a preset sampling period so as to determine actual distance between the two eyes of the human face image; determining M images during sampling, calculating average of the actual distance between two eyes of each of the M images, and prompting the users to regulate the visibility range from the eyes to the screen if the average is higher than the safety threshold valve; otherwise, returning to sampling. By the monitoring method, the visibility range of the user can be monitored in real time, the user can be prompted to keep moderated distance from the screen, health of the user is guaranteed, and intelligent and personalized service are provided for the users.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for monitoring the visual distance from human eyes to a screen. Background technique [0002] At present, there are more and more electronic products, such as computers, notebook computers, mobile terminals, e-books and so on. In the process of using these electronic products, users tend to read the content on the screen for a long time, which causes the fatigue of human eyes. In order to reduce the uncomfortable feeling of human eyes, users will unconsciously approach the screen, thereby reducing the burden on human eyes and achieving the purpose of easy reading. [0003] However, medical experts suggest that the visual distance from the human eye to the screen should be kept outside a certain range, otherwise it is not conducive to the protection of vision. In actual situations, users usually open the viewing distance appropriately after they are actively aware of the chang...
