Because early infrared imaging devices are very expensive, thermal infrared human detection technology is mainly used in the military field. For example, in the case of poor visual conditions, reconnaissance determines the size and distribution of enemy forces, assists in formulating battle plans; helps to quickly find and Aim at enemies in the dark or under general cover, etc.

 

With the technological development and price reduction of infrared imaging devices, the application of thermal infrared human target detection technology has gradually expanded to many civilian fields. For example, in the traffic field, it is used for traffic monitoring of pedestrians and vehicles under conditions such as heavy fog, rain and snow, and at night; in the security field, it is used for nighttime security monitoring in residential quarters, banks, ports, factories, etc.; in law enforcement In the field of night patrols, chasing and searching for criminal suspects, anti-terrorist operations and hostage rescue, etc.; in the field of emergency rescue, it is used for searching for trapped persons in fire scenes, underground caves, mine accidents, and earthquakes; in the field of computer vision, it supports auxiliary Human-computer interaction requirements in driving, robot vision, AR/VR systems, by capturing human gestures, gait, facial features, etc. in the scene, to achieve user authentication, visual navigation, action command response, etc.; in the medical field, used for judgment Pathological state, because when a person is sick, his whole body or local thermal balance is destroyed, by comparing the thermal image of the human body with the thermal image of the human body in the normal physiological state, the pathological state can be judged, especially for metabolic diseases ( Diabetes), early breast tumors, the diagnosis of nervous system diseases, and the diagnosis of traditional Chinese medicine.
