Body temperature screening and alarming system and working method thereof

Abstract

The invention discloses a body temperature screening alarm system and a working method thereof, and the system comprises face detection equipment which is used for detecting the face position information of a face, wherein the face position information comprises the contour of a face and the position information of face key points; temperature measuring equipment which is used for measuring temperature information in the temperature measuring area; information processing equipment used for determining the surface temperature of the face key point according to the face position information detected by the face detection equipment and the temperature information measured by the temperature measurement equipment, calculating the in-vivo temperature, judging a person corresponding to the in-vivo temperature exceeding a set threshold temperature as a heating target, carrying out face screenshot on the heating target, and sending out a high-temperature alarm. In this way, non-face high-temperature objects can be automatically avoided, false detection is avoided, meanwhile, the body temperature of a person with part of face skin shielded by clothes is accurately detected, missing detection is avoided, the accuracy of body temperature monitoring is guaranteed, early warning can be conducted on multiple heating persons, and secondary hand detection on the heating persons is facilitated.

Description

technical field [0001] The invention relates to the technical field of infrared thermal imaging, in particular to a body temperature screening and alarm system and a working method thereof. Background technique [0002] Non-contact infrared thermometers have been widely used in industrial sites for point, line, and surface temperature detection. Infrared thermal imaging detection technology is used for non-contact detection of operating industrial equipment, and the distribution of its temperature field is photographed, and various parts are measured. The temperature value can be used to diagnose various working conditions and internal faults, which has the advantages of real-time, intuitive and fixed measurement. However, infrared thermal imaging temperature measurement is greatly affected by factors such as the atmosphere, ambient temperature, and temperature measurement distance. When each infrared thermometer leaves the factory, a blackbody analog heat source will be set...

Problems solved by technology

And because the average and local maximum are used to screen suspicious persons, it is impossible to simultaneously intercept and alarm multiple suspicious target pictures for multiple suspected feverish persons appearing in the scene, resulting in missed detection
