Body temperature measuring method and device based on infrared image face detection

Abstract

The invention relates to a body temperature measuring method based on infrared image face detection. The body temperature measuring method comprises: obtaining an infrared image and a temperature distribution diagram through an infrared temperature measuring camera; performing face analysis based on the infrared image to obtain a face area; based on the temperature distribution diagram, performingtemperature analysis, and determining a body temperature area; calibrating the face region according to the body temperature region, and determining a region of interest; and calculating the averagetemperature of the region of interest according to a preset algorithm. Remote portable body temperature measurement can be realized, the face area of the measured human body is accurately positioned through face analysis of the infrared image, the face area is calibrated in combination with the temperature distribution diagram, and the method has the advantages of high measurement accuracy and lowomission ratio.

Description

technical field [0001] The present invention relates to the application field of augmented reality, in particular to an augmented reality body temperature measurement method and device of an infrared temperature measurement camera. Background technique [0002] The traditional method of measuring body temperature is generally by using a mercury thermometer or a forehead thermometer to measure temperature at close range, which usually requires a long measurement time and close contact. In the case of a large flow of people, the measurement speed is slow; in addition, due to the global outbreak of the new coronavirus, close contact will increase the risk of infection, so there is an urgent need for a method that can achieve long-distance rapid body temperature detection. [0003] The existing infrared temperature measurement camera can realize non-contact body temperature detection at a fixed location, but the infrared temperature measurement camera must be fixed on the field,...
