In waterproof plugging construction, waterproofers often use "infrared thermal imaging cameras" for leak detection. So, in a special period, can the infrared thermal imager replace the body temperature infrared thermal imager? The answer is yes! sure! Let's take a look at how a thermal imaging camera works.
Infrared thermal imagers work on the principle that "any object above absolute zero emits infrared radiation". Therefore, the detector of the infrared thermal imaging camera can passively receive the infrared radiation of the measured object, convert it into a temperature value, and finally visually display the temperature distribution of the measured object. It has the characteristics of non-contact measurement, temperature visualization, large-area measurement, and it is not harmful to the human body. This also means that the use of thermal imaging cameras for body temperature screening can actually be safer and more efficient and avoid missed inspections.
In the process of body temperature screening, the human body infrared thermal imaging camera occasionally has false detections. This is because the normal body temperature of the human body is indeed fluctuating. The body temperature is stimulated by the internal and external environment temperature, and the body temperature is automatically adjusted to achieve a new body heat balance. to adapt to the environment. The key to how to reduce false detections and missed detections caused by normal body temperature regulation is not the measured temperature, but the judgment of abnormal alarm temperature. The alarm temperature should be a floating value. Some thermal imaging cameras with relatively complete functions have the function of epidemic prevention detection. Through special algorithms, they can automatically adjust the temperature alarm value, find "potential patients" with abnormal body temperature exceeding the crowd, and immediately call the police.
Generally speaking, the temperature at the eye socket is close to the core temperature of the human body, which is especially suitable for representing the real body temperature of the human body. Therefore, in addition to the above-mentioned special algorithm for automatically adjusting the alarm temperature value, different from other thermal imaging cameras, the body temperature infrared thermal imaging camera with epidemic prevention detection function has a face recognition algorithm, which automatically measures the temperature at the eye socket of the human body. And each subject in the crowd is tested one by one, which can guide users to quickly complete accurate temperature screening.
The thermal imager screen projection function of the thermal imager can output the images generated on the screen to other display devices. Using the characteristics of the screen projection and the non-contact measurement of the thermal imager, it can ensure that the inspector and the tested person keep a safe distance, to prevent cross-interference.
Functionally speaking, thermal imaging cameras can replace body temperature thermal imaging cameras. At present, many large-scale transportation hubs such as railway stations and airports have gradually used higher-performance thermal imaging cameras for body temperature verification. For us, there are ready-made leak detectors, and we can make the best use of them in the current epidemic situation.
