Problems solved by technology

[0003] The purpose of this invention is to aim at the current thermal imager which is mainly used for tracking and temperature measurement of individuals in the crowd, that is, only for the forehead temperature of a certain frame of the human body. Observing static signals, but not using the dynamic signals continuously collected by the thermal imager, a non-contact joint detection method of body temperature and respiration rate is proposed

Abstract

The invention provides a non-contact body temperature and respiration rate combined detection method. The method comprises the steps of acquiring video image data under the target background of a human body by a thermal imager or a night vision device, wherein the video image data comprise temperature field information in a scene, and the temperature of the human body can be directly read in the thermal imager or the night vision device; amplifying the acquired video image data by using a micro motion amplification technology; and carrying out optical flow calculation on the amplified video image data to finally obtain an accurate value of respiration rate. According to the method, infrared video images are captured by the thermal imager or the night vision device, the body temperature andthe respiration rate of the crowd are jointly detected, and even under the condition that the body temperature is normal due to the fact that a specific target crowd takes antipyretics, the specifictarget crowd can be identified through the characteristic change of the respiration rate of the specific target crowd and an alarm is given.

Description

technical field [0001] The invention belongs to the technical field of video signal analysis, in particular to a non-contact joint detection method of body temperature and respiration rate. Background technique [0002] Abnormal body temperature is one of the common symptoms during the outbreak of various infectious diseases. At present, human body temperature measurement infrared thermal imaging cameras have been widely used in the rapid detection and screening of people in public places. Its temperature measurement is accurate and efficient, and it is very suitable for places with dense traffic such as hospitals, stations, etc., and it uses infrared non-contact characteristics to obtain infrared rays emitted by the human body and form a temperature image in real time. When a disease or function occurs somewhere in the human body When it changes, the blood flow in the place will change accordingly, resulting in a change in the local temperature of the human body, which is ...
