Method and system for preventing myopia by monitoring distance between eyes and screen

Abstract

The invention discloses a method and system for preventing myopia by monitoring the distance between eyes and a screen. The method and system for preventing myopia by monitoring the distance between the eyes and the screen is used for detecting the distance between the face of a person and the screen and capable of finding out and reminding automatically when the distance is too short, and therefore the eyesight of children can be effectively protected. According to the technical scheme, the method comprises the steps of collecting images in front of the screen; processing the collected images, identifying key characteristics on the face and calculating parameter values of the key characteristics on the face; comparing the calculated parameter values of the key characteristics on the face with corresponding preset parameter values of the key characteristics, confirming that the distance between the face and the screen is smaller than a preset distance if the parameter values of the key characteristics are larger than the preset values based on the perspective law that the object is big when near and small when far, and reminding people of the short distance.

Description

technical field [0001] The invention relates to a technology for protecting eyesight through facial feature recognition, in particular to a method and system for protecting children's eyesight when children watch a screen. Background technique [0002] The current society has entered an information society, and people use electronic devices to communicate, surf the Internet, and play games. People spend more time facing the screens of various devices than ever before. [0003] The development of science and technology has brought TVs and game consoles into thousands of households, and computers have become a common tool for intellectual development since they were learned from babies. The screens of TVs, computers, and game consoles all produce invisible electromagnetic radiation. Generally, the dose of these radiations is very small, and they are all below the safe range of not harming human organs. However, if you touch the screen for a long time every day, it will cause...

Problems solved by technology

However, if you touch the screen for a long time every day, it will cause certain damage to the human eye, such as conjunctivitis, punctate keratitis, and lens opacity.

If the quality of these electrical appliances is poor, the displayed image is not clear, the writing is blurred, the color contrast is not soft, the picture is distorted or flickering, etc., all of which will affect the quality of imaging on the retina, which will cause the normal physiological function of the eye to be out of balance. Staring at the screen for a long time can cause fatigue of the inner and outer muscles of the eyes, and it is easy to cause myopia

[0004] Especially when children watch TV, computers or portable electronic devices, they always like to sit in front. In this way, the children's eyes are stimulated by the strong light from the screen for a long time, which not only easily reduces the child's visual acuity and adaptability, but also Moreover, it is easy to cause the reduction of the adjustment function of the ciliary muscle, and the lens gradually becomes convex, resulting in a decrease in children's vision, and it is impossible for parents to always pay attention to the distance between the child and the screen when watching TV or playing on the computer.
