Infrared thermal camera for Human Temperature Detection
In view of the outbreak of the epidemic, one of its characteristics is the typical symptom of fever and cough, non-contact personnel temperature screening has become a key prevention tool in the surveillance and prevention of the epidemic in public areas today. Compared with traditional contact temperature screening equipment, non-contact equipment can rely on infrared intensity for online temperature monitoring of the target body, achieving effective and rapid screening of the population and significantly improving the screening efficiency. In this epidemic prevention and control, infrared thermography-based temperature screening equipment infrared thermal camera equipment is in high demand. The following are the details of the infrared thermal camera to detect the human body temperature information.

Infrared thermal camera how to achieve the human body temperature measurement?
Normal human body temperature distribution has certain stability and characteristics, the body temperature of various parts of the body is different, forming a different thermal field, when a disease or functional changes in the human body, the blood flow will change accordingly, resulting in local temperature changes in the human body, expressed as a high or low temperature, usually, the human body surface of the higher temperature is generally in the root of the nose around and eye sockets, the inside of the mouth and other parts, the part of the More blood vessels and thin epidermis, can well reflect the temperature state of the measured human body, so the infrared thermal camera to detect the location of the human face is appropriate.
According to this principle, the infrared radiation of the human body is collected by a thermal imaging system and converted into a digital signal to form a pseudo-color thermogram. Using special analysis software, the thermogram is analyzed by professional physicians to determine the location of human lesions, the nature of the disease, and the degree of lesions, which provides a reliable basis for clinical diagnosis.
Why use an infrared thermal camera to do the initial screening of body temperature?
1. Suggest inflammation: rhinitis, paranasal sinusitis, oral inflammation, laryngitis, thyroiditis, pneumonia, cholecystitis, appendicitis, gastroenteritis, prostatitis, adnexitis, and other inflammation in various parts of the body.
2. Early warning of tumors: nasopharyngeal cancer, thyroid cancer, lung cancer, breast cancer, liver cancer, stomach cancer, intestinal cancer, skin cancer, and other cancers
3. Prompting of peripheral nerve diseases: prompting of facial paralysis, facial spasm, migraine, trigeminal neuralgia. Prompts and studies of skin diseases, measurement of area and depth of burns and frostbite, observation of the efficacy of skin implants.
4. Suggestions of vascular diseases: The temperature of human limbs is mainly determined by the state of blood circulation, and when there are vascular lesions, blood circulation is impaired and skin temperature decreases. Such as occlusive vasculitis, arterial embolism, aneurysm, etc., usually manifest as the abnormal temperature at the lesion site, and the infrared thermography can clearly show the lesion site and scope. With an infrared thermal camera, not only the existence of lesions can be shown, but also the degree and extent of lesions in each toe. Through early diagnosis and timely treatment, serious damage to the limbs, such as ulcers and necrosis, can be avoided.
Infrared thermal camera, which fits the requirements of epidemic prevention and control for efficient and safe temperature measurement, has recently attracted much attention from various parties. Infrared thermal imaging camera can achieve a longer distance, the non-contact situation of multiple targets at the same time for temperature detection, can be less personnel contact, relatively safe and convenient, but its accuracy is affected by the external environment, it is recommended that all places according to the actual situation to choose to use.
