Problems solved by technology

In this body temperature detection method, the temperature measurement distance supported by the handheld device is relatively short, and cross-infection of personnel is prone to occur due to insufficient protective measures; since the energy radiated by objects such as the human body will decay in the atmosphere, when the temperature measurement distance is long At the same time, the current body temperature detection method cannot obtain accurate temperature measurement results; at the same time, this method can only measure one person at a time, and the efficiency is very low

Abstract

The invention provides a body temperature correction method and device and electronic equipment, and relates to the technical field of infrared temperature measurement. The method comprises the steps:obtaining a reference image frame pair which is collected by a camera group and is formed by a visible light image frame and a thermal imaging image frame; performing pedestrian detection on the visible light image frame, and determining a candidate reference image frame pair containing the target person and a positioning area of the target person in the candidate visible light image frame of thecandidate reference image frame pair according to a detection result; determining a positioning area of the person in the thermal imaging image frame according to the space-time corresponding relation between the visible light image frame and the thermal imaging image frame and the positioning area of the target person contained in the visible light image frame; determining the initial temperature of the target person according to the pixel value of the target person in the positioning area in the candidate thermal imaging image frame; and correcting the initial temperature based on the distance information between the target person and the thermal imaging camera to obtain the body temperature of the target person. According to the invention, the accuracy of body temperature measurement and correction can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of infrared temperature measurement, in particular to a body temperature correction method, device and electronic equipment. Background technique [0002] When outbreaks such as new crown pneumonia, influenza, etc., there is usually a greater demand for body temperature detection equipment. At present, most commonly used temperature detection devices are handheld devices, which require staff to hold the handheld device close to the person to be checked, and measure the temperature one by one. In this body temperature detection method, the temperature measurement distance supported by the handheld device is relatively short, and cross-infection of personnel is prone to occur due to inadequate protective measures; since the energy radiated by objects such as the human body will attenuate in the atmosphere, when the temperature measurement distance is long At the same time, the current body temperature detecti...
