Due to the epidemic, the current temperature measurement technology of the Face Recognition and temperature measurement integrated machine is already a human technology in the field of access control and attendance. It is not only used in enterprises, stations, airports, office buildings, communities and other places, but even in some families. Face recognition temperature measurement machine, because it has an access control function, it can be used to open the door.

The face recognition and temperature measurement all-in-one machine recognizes the human face through the binocular camera. After the face is recognized, the upper black Body Temperature Measurement Module starts to work. After the temperature is measured, the current human body temperature will be displayed on the screen. It combines the attendance machine, temperature measuring gun, access control, etc., and mainly has the following highlights:
1. Powerful functions. In addition to face recognition and temperature measurement, it can also provide access control, attendance, personal identification comparison, automatic report generation, etc.
2. High degree of intelligence. Through the Android system and Windows system, you can set the switch time to avoid unnecessary waste, and take pictures automatically during attendance.

The thermal imaging principle of ZECHENG Temperature Measurement Module is the same as that of thermal imaging cameras on the market. The difference lies in the sensor range and temperature measurement algorithm.
1. Sensor range: The face temperature measuring function of many manufacturers on the market can demonstrate the measurement of hot water temperature of 50℃ or even 60℃. This is because industrial sensors are used. The range of industrial sensors is generally from -20°C to 150°C. The larger the range of the same sensor, the higher the error. ZECHENG face temperature measuring machine adopts a custom sensor, the range is customized from 26.6 to 48.7, and the algorithm is optimized to an ambient temperature of 20~30°C, a distance of 30~50cm, a measurement time of 2 seconds (no black body required), and an accuracy of ±0.3°C.
2. Temperature measurement algorithm: ZECHENG temperature measurement module comes from Taiwan, using sensors from top-tier manufacturers such as Seiko and Omron. The temperature measurement algorithm has been precipitated for more than 10 years, and the related products have been used in the baby temperature measurement system for 5 years, and related patents have been obtained. The abnormal temperature above 37.3℃ can be accurately tested in the ambient temperature of 15℃~35℃. The temperature measurement method of most manufacturers on the market is to manually correct the relative temperature value of the sensor according to the value obtained by the forehead gun (the temperature of each person is different). The ambient temperature needs to be calibrated once, and the individual temperature is different. There are also uncertainties in human body temperature. It is equivalent to a laboratory product, a non-commercial product, which will miss people with low-grade fever and lose the original intention of temperature screening.
ZECHENG's face recognition and temperature measurement all-in-one machine has undergone high-precision black body correction at the factory, and does not need to be manually corrected by forehead thermometers, ear thermometers, etc., to ensure accurate and effective body temperature data.
