Abstract

An anti-epidemic access control device includes an image capture device, a low-resolution infrared sensor, a judging device, a warning device, and a gate device. The image capturing device captures facial images. The low-resolution infrared sensor generates an infrared light image corresponding to the facial image. The judging device judges whether the face image is wearing a mask. If the face image is already wearing a mask, it captures the area of the face image corresponding to the infrared light image where the mask is not worn, and judges whether the body temperature exceeds the body temperature bottleneck value. If it is judged that the mask is not worn or the body temperature exceeds the body temperature bottleneck value, a warning signal is generated. When it is judged that the face image is wearing a mask and the body temperature is lower than the body temperature bottleneck value, an activation signal is generated. The warning device is activated when the warning signal is received. The gate device receives the start signal and opens for a certain period of time and then closes.

Description

Epidemic prevention access control equipment

This creation is related to the field of access control, especially a kind of anti-epidemic access control equipment.

Nowadays, the technology of face recognition is quite mature, mainly based on skin color and facial features. Under the influence of the current Wuhan pneumonia epidemic, it is known that wearing a mask is an effective way to avoid infection. However, for human face judgment, the color and shape of the mask may cause the face shape to be unable to be effectively judged, and there are loopholes in the control of entry and exit.

In addition, current infrared sensors, such as FLIR’s E95, cost approximately NT$300,000 to 500,000, which is a heavy burden for general office buildings, factories, and other environments that need to control the entry and exit of personnel. In addition, although the infrared sensor can track the human body for measurement, it is very susceptible to the influence of the environment, such as wind direction, hot food, and coffee, and is still not accurate enough. In addition, most of the infrared sensors on the market are closed software, which makes it difficult to cooperate with existing gate controls.

In order to solve the aforementioned problems, an anti-epidemic access control device is provided here. The anti-epidemic access control equipment includes an image capture device, a low-resolution infrared sensor, a judging device, a warning device, and a gate device.

The image capture device captures facial images at a specific distance. The low-resolution infrared sensor generates an infrared light image corresponding to the facial image at a certain distance. The judging device is electrically connected to the image capture device and the low-resolution infrared sensor, receiving the facial image and infrared light image and judging whether the facial image is wearing a mask, if it is judging that the facial image is wearing a mask, the corresponding infrared is captured The light image corresponds to the area of the face image where the mask is not worn, and it is determined whether the body temperature exceeds the body temperature bottleneck value. If it is judged that the face image is not wearing a mask, or the body temperature exceeds the body temperature bottleneck value, a warning signal is generated. When it is judged that the face image is wearing a mask and the body temperature is lower than the body temperature bottleneck value, an activation signal is generated. The warning device is electrically connected to the judging device, and is activated when the warning signal is received. The gate device is electrically connected to the judging device, receives the start signal and is turned on for a specific time, and then turned off.

In some embodiments, the image capturing device and the low-resolution infrared sensor are jointly disposed in the housing.

In some embodiments, the resolution of the low-resolution infrared sensor is 80×60 pixels.

In some embodiments, the sensitivity of the low-resolution infrared sensor is 0.01 to 0.1 degreeC.

In some embodiments, the anti-epidemic access control device further includes a screen, which is connected to a determination device, and presents a facial image, an infrared light image, and a body temperature determined by the determination device. In more detail, the screen is a touch screen, and the touch screen includes control buttons for controlling the gate device.

In some embodiments, the body temperature bottleneck value is 36.4 to 37.5 degrees Celsius.

In some embodiments, the warning device is an alarm or a warning light.

In some embodiments, the anti-epidemic access control equipment further includes an activation device, which is electrically connected to the image capture device and the low-resolution infrared sensor, and when the activation device is triggered, the image capture device and the low-resolution infrared sensor are activated For shooting, the activation device is set in the shooting area, and the shooting area is a certain distance away from the image capturing device and the low-resolution infrared sensor.

In more detail, the specific distance is 0.8 to 2 meters.

In more detail, the activation device is a piezoelectric switch.

It can be understood from the foregoing embodiments that, by combining an image capturing device and a low-resolution infrared sensor to perform a body temperature test on the subject's face, the interference of the ambient temperature can be greatly reduced. Through the judging device, it is possible to accurately judge the subject's face without being affected by the mask, and then combined with the gate device to achieve the effect of effective control and reducing the route of virus transmission.

In the following description, when an element is referred to as being "connected" or "disposed" to another element, it can mean that the element is directly located on the other element, or there may also be intermediate elements.

To activate the warning device 30 electrically connected to the judging device 20. Here, the warning device 30 can be an alarm or a warning light, or a combination thereof.

In the body temperature determination step S40, the determining device 20 determines whether the body temperature of the region where the mask is not worn on the face image corresponding to the infrared light image exceeds the body temperature bottleneck value. For example, the body temperature bottleneck value is 36.4 to 37.2 degrees C, preferably 36.6 to 36.6. 37 degrees C. This is just an example. The regulator can set it based on actual environmental conditions or the recommendations of the Epidemic Prevention Center.
