Abstract

The utility model discloses anti-drowsiness glasses, which are provided with a battery unit, an image recognition sensor unit and a reminder unit in the mirror frame; the battery unit provides power supply for the sensor unit and the reminder unit; the image recognition sensor unit By monitoring the opening and closing state of the glasses wearer's eyes, it is judged whether the wearer is in a drowsy state; when it is judged that the wearer is in a drowsy state, the sensor unit sends a control signal to make the reminder unit work to remind the wearer of glasses. Because the utility model adopts the image recognition sensor unit to dynamically monitor the state of the wearer's eyes, when the human body begins to doze off, the time of closing and opening the eyes will produce obvious changes, and the state of the eyes can be monitored in the first time. Accurately detect that the human body has entered a drowsy state, and remind the wearer through vibration or sound prompts.

Description

Anti-drowsiness glasses

technical field

The utility model relates to a pair of glasses, in particular to a pair of glasses with the function of preventing drowsiness.

Background technique

Wearing glasses is prone to visual fatigue, especially in the process of work and study, people who wear glasses tend to doze off. In some cases, if the person who wears glasses dozes off, it may bring great potential safety hazards to the personal safety of himself or others. For example, a driver wearing glasses must not doze off when driving. Therefore, there is a need for glasses that remind the wearer in time when the human body is about to doze off.

Existing glasses with reminding function mainly adopt two ways of realization: one adopts the mode of infrared induction, by dynamically monitoring the distance between the glasses and a certain fixed point, when the distance is too close, it is assumed that the wearer has started to doze off. This way can't be reminded in time for dozing off in some situations, for example: if the driver falls asleep on the bolster at the back, because the head hardly moves, so it can't give an alarm prompt. The other is to judge whether the wearer is dozing off by monitoring the horizontal position of the glasses. When the inclination angle between the glasses and the horizontal position reaches a certain level, the wearer is considered to be dozing off. In addition to the fact that there is no reminder in the case of this reminder, the wearer may be mistaken for dozing off due to the unconscious tilt of the head, resulting in a false alarm for situations that should not be reminded.

Contents of the invention

The utility model provides a pair of glasses which can be found and reminded in time when the wearer just starts to doze off.

The anti-drowsiness glasses proposed by the utility model are provided with a battery unit, an image recognition sensor unit and a reminder unit in the frame; the battery unit provides power supply for the sensor unit and the reminder unit; The state of the eyes of the wearer of glasses judges whether the wearer of glasses is in a drowsy state; when it is judged that the wearer of glasses is in a drowsy state, the sensor unit sends a control signal to make the reminder unit work to remind the wearer of glasses.

Preferably, lenses are arranged in the frame of the spectacle frame.

Preferably, the mirror frame also includes a functional switch, which is connected in series to the power supply circuit for the battery unit to supply power to other units.

Preferably, the image recognition sensor unit includes: a microprocessor, an image recognition sensor and a lens assembly, the lens assembly is arranged on the inner side of the mirror frame of the spectacle frame or the inner side of the front part of the mirror leg, so that the lens assembly captures the wearer from the front or side The image information of one of the eyeballs, the image recognition sensor recognizes and processes the image information, and transmits the processing result to the microprocessor, and the microprocessor judges whether the wearer is in a drowsy state.

Preferably, the reminder unit is one or both of a sound alarm and a vibration alarm.

Preferably, the sound alarm is located on the temple of the mirror frame.

Preferably, there are two vibration alarms, which are respectively located on the left and right temples of the mirror frame.

Preferably, the vibration alarm is located in the middle of the frame of the frame.

Since the utility model adopts the image recognition sensor unit to dynamically monitor the wearer's eye state, when the human body begins to doze off, the frequency and duration of eye closing and eye opening will change significantly, and the eye state can be monitored by monitoring the eye state. It can accurately detect that the human body has entered a drowsy state at the first time, and remind the wearer through vibration or sound prompts.

Description of drawings

Fig. 1 is a structural principle diagram of a preferred embodiment of the anti-drowsiness glasses of the present invention;

Fig. 2 is the eye-opening image information photographed in the preferred embodiment of the anti-drowsiness glasses of the present invention;

Fig. 3 is a closed-eye image captured in a preferred embodiment of the anti-drowsiness glasses of the present invention.

Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

The preferred embodiment of anti-drowsiness glasses as shown in Figure 1 is provided with battery unit 2, image recognition sensor unit 1 and reminder unit 3 in the mirror frame; Battery unit provides power supply for sensor unit and reminder unit; Image recognition sensor The unit judges whether the wearer is dozing off by monitoring the eye state of the wearer of glasses; when it is judged that the wearer is dozing off, the sensor unit sends a control signal to make the reminder unit work to remind the wearer of glasses. The battery unit can be a button battery, and the lens assembly in the image recognition sensor unit is arranged on the inner side of the frame or the inner side of the front part of the mirror leg, so that the lens assembly can collect image information of one of the eyeballs of the wearer from the front or side. Lens can also be arranged in the picture frame of the picture frame. The battery unit, the image recognition sensor unit and the reminder unit are all arranged on the mirror legs among Fig. 1 . The reminder unit can adopt one or both of sound alarm and vibration alarm. Two shock alarms can be set, which are respectively located on the left and right mirror legs of the mirror frame. The vibration alarm can also be arranged in the middle part of the picture frame of the picture frame. In addition, a functional switch is included in the mirror frame, and the functional switch is connected in series to the power supply circuit for the battery unit to supply power to other units. When the reminder is not needed, just turn off the function switch.

The image recognition sensor unit includes: a microprocessor, an image recognition sensor and a lens assembly. As shown in Figures 2 and 3, the lens in the lens assembly of the image recognition sensor unit is aimed at an eyeball from the side to obtain the image of the eyeball. Figure 2 is an eye-opening image, and Figure 3 is an eye-closing image. The image recognition sensor can find out whether the eyes are currently closed, open, blinking, etc. through pattern recognition, and through the pre-determined physiological data in the microprocessor, such as the frequency and duration of eye closure and eye opening. , to judge whether the wearer has entered a drowsy or sleeping state, and if it has entered a drowsy or sleeping state, send instructions to the sound and vibration alarm to remind the wearer.
