Face recognition temperature measurement: just look at you in the crowd

At present, the domestic epidemic has been basically controlled. In order to prevent another large-scale outbreak of the epidemic, the prevention and control measures such as temperature testing, wearing masks, and disinfection in most public places and corporate office buildings have begun to become normalized management. The non-contact, unattended, and fast-sensing face recognition temperature measurement equipment has been widely used during the epidemic.

Since the introduction of the face recognition temperature measurement series products this year, they have been supported by the epidemic prevention agencies, covering public health management, access control and attendance, security monitoring, smart retail and other scenarios.

1. Flexible and expandable
The system functions are flexible and expandable, with column type, wall type, desktop type and other forms, and can be linked with metal security gates, gate access control, disinfection modules, etc. The upgrade can also support functions such as visitor registration and ID identification. Through the ID card module, read the second-generation ID card information, compare the ID card, and control the access prohibition of gates.
Second, face recognition
Cope with a variety of light:
Using light preprocessing technology, the image is normalized to a picture with no light, so that the algorithm can cope with various lighting conditions.
Cope with a variety of makeup:
Using data enhancement strategies, relying on GAN technology to automatically generate and expand training data sets to deal with scenarios such as makeup, wearing glasses / taking off glasses, wearing masks, and aging / youth.
Anti-misunderstanding technology:
After the model selects the most similar face, an additional post-processing algorithm is introduced to effectively solve the occurrence of misrecognition under the large-capacity face database.
Three, temperature measurement
Using medical-grade infrared thermal imaging sensor, the temperature measurement accuracy can reach ±0.2℃; the small-angle FOV temperature sensor can accurately measure the forehead temperature, which can avoid the influence of hair, clothes, air, and heat sources; the calibration fitting can adapt to different environmental temperatures.
