The ability of thermal imaging cameras to translate temperature into visual images enables them to do body temperature screening. Temperature points are represented by the pixels in each thermal image, and the quantity of temperature points is dependent on the infrared pixels of the device itself, such as FOTRIC692 The efficiency will be much increased because a thermal image's infrared pixels are 384*288 and include 110,000 temperature points, which is the same as using 110,000 temperature measuring guns at once to measure temperature.
At the entry and departure of the traffic station, the fixed infrared thermal imaging body temperature detection equipment is often installed. It is possible to find about 10 things. The constant temperature "black body" (in the red box in the above figure) that is consistent with the thermal radiation energy of the average human body is typically included in the fixed infrared thermal imaging body temperature detection system in order to ensure the detection accuracy. This "black body" serves as a reference standard for real-time calibration. Fixed infrared thermal imaging body temperature monitoring technology is currently quite expensive, typically costing over 100,000 yuan.
The detection accuracy (some errors are larger than 0.5°C), field of vision, and detection distance (some only 0.5m) of handheld infrared thermal imaging temperature measurement equipment are often lower than those of the fixed type. as well as portable infrared temperature measuring apparatus. The low precision one costs between 4,000 and 5,000 yuan, and it may only have an accuracy of 2°C. In contrast, the high precision one costs tens of thousands of yuan.
The fixed infrared thermal imaging body temperature detection system is comparable to the infrared thermal imaging temperature measurement security gate, but the precision and range of the detection are less. As an illustration, consider the Hikvision infrared thermal imaging temperature measurement security gate in the above video. The test distance is 0.3-3 meters, and the precision is 0.5°C. These gadgets cost around $20,000.
