Abstract

The utility model discloses an eyesight protecting system for a computer display. The eyesight protecting system comprises an image acquisition module, a mechanical face recognition module and an alarm reminding module. The image acquisition module acquires image information of faces of computer users continuously, and then transmits data to the mechanical face recognition module mounted on a computer by the aid of a computer external interface. The mechanical face recognition module analyzes face data of the users, determines whether the users sit before the computer display for a long time or not and whether the users blink or not, and then sends the analyzed data to the alarm reminding module. The alarm reminding module can remind the users not to stare at the computer for a long time but to blink frequently to relieve symptoms such as dryness periodically. Eyesight of computer users can be protected after the image acquisition module, the face recognition module and an alarm reminding software are installed on a general personal computer. The eyesight protecting system has the advantages of low cost, convenience in use and the like.

Description

computer monitor eye protection system

technical field

The utility model relates to a vision protection device, in particular to a computer display vision protection system capable of identifying the state of human eyes and prompting users to take a break.

Background technique

Normal eyes blink about 15 times per minute. Blinking is good for the eyes: firstly, it can clean and moisten the eyeballs, and secondly, blinking can protect the eyes. When the wind and sand or flying insects approach the eyes, the eyelids will blink naturally. It blocks sand and bugs. When the eyes feel tired, blinking a few times will make you feel more comfortable, because the light is interrupted at the moment of blinking, giving the eyes a short rest. When you blink, the tears can evenly moisten the cornea and conjunctiva, keep the eyeballs from drying out, keep the cornea shiny, and remove dust and bacteria in the conjunctival sac. If you don't blink, the tear film on the eyeball will evaporate quickly, and we will feel dry, uncomfortable, stinging, and tearful.

When using a computer, the exposed eye surface area between two blinks increases and the number of blinks decreases, which will accelerate the evaporation of tears, which is the main cause of dry eyes. In addition, facing the computer screen for a long time will aggravate eye fatigue. With the development of computer technology, ordinary computers can complete the analysis of face images, and regularly remind users to pay attention to eye hygiene.

Utility model content

The utility model provides a convenient, flexible and low-cost vision protection system for computer users, which can remind users to pay attention to eye hygiene in real time.

In order to achieve the above object, the technical solution adopted by the utility model is:

The computer display vision protection system includes an image acquisition module, an image analysis module and an alarm reminder module. The image acquisition module is connected to the image analysis module installed on the computer through an external data communication interface of the computer, and the image analysis module and the alarm reminder module realize data communication.

The image analysis module is composed of an image preprocessing module, a face analysis module and a blink analysis module.

The alarm reminder module is composed of a timer module, a text alarm module and a sound alarm module.

The image acquisition module is connected to the image preprocessing module installed on the computer through the computer USB interface, the image preprocessing module is connected to the face analysis module and the blink analysis module, and the face analysis module and the blink analysis module are connected to the timer module, The timer module is connected to the text alarm module and the sound alarm module.

The image acquisition module uses an ordinary USB interface camera, and the output signal of the camera is transmitted to the image preprocessing module installed on the computer through the computer USB interface. Face analysis and blink analysis modules; face analysis and blink analysis modules respectively analyze whether the current user is staring at the computer screen and whether the current user blinks, and the analysis results are transmitted to the back-end timer module through system messages; the timer module calculates The blinking frequency of the user and the duration of the user's operation of the computer remind the user to pay attention to rest, and the reminder action is generated by the text alarm module or the sound alarm module.

The vision protection system for computer monitors provided by the utility model adopts a simple, practical, flexible and cost-effective solution. A low-cost USB camera is installed on the computer, and special face recognition software and alarm software are installed, that is, The purpose of protecting the eyesight of computer users can be realized, and the use cost is greatly reduced.

Description of drawings

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a schematic diagram of the utility model.

Fig. 2 is a structural schematic diagram of the utility model.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

The utility model adopts the system shown in Figure 1, which is mainly composed of an image acquisition module, an image analysis module and an alarm reminder module. The image acquisition module is a hardware device, and the image analysis module and the alarm reminder module are application software installed on the computer.

The specific implementation of the system shown in FIG. 1 is realized through the structure shown in FIG. 2 .

As shown in Figure 2, the whole system consists of image acquisition module, image preprocessing module, face analysis module, eye blink analysis module, timer module, text alarm module and sound alarm module. Wherein the output end of the image acquisition module is connected to the computer through the USB interface, and the image data collected is output to the input end of the image preprocessing module; the output end of the image preprocessing module is connected to the input of the face analysis module and the blink analysis module terminal; the output terminal of the face analysis module and the blink analysis module is connected to the input terminal of the timer module, and the output terminal of the timer module is connected to the input terminal of the text alarm module and the sound alarm module.

In this embodiment, a camera with a USB interface is used as an image acquisition device, and a computer is used as an information processing unit. The final alarm module shows the alarm information on the display, and can choose whether to sound the warning.

The USB camera continuously collects the facial image information of the computer user, and transmits the data to the image analysis software module installed on the computer through the external USB interface of the computer. The image analysis software analyzes the user's facial data to determine whether the user has been sitting in front of the computer monitor for a long time and Whether to blink, and send the analyzed data to the alarm reminder module. The timer module calculates the user's blinking frequency and the duration of the user's operation of the computer. If the user's blinking frequency is less than 1/6 Hz or the user continues to operate the computer for more than 2 hours, the user is reminded to take a break, and the alarm reminder module will regularly remind the user not to stare at it for a long time The computer should also blink more appropriately to relieve symptoms such as dry eyes and astringent eyes.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments.
