Embodiment 1

[0029] A non-contact temperature measurement system such as figure 1 As shown, the measurement system includes a visible light camera, thermal camera, embedded processor and human-computer interaction equipment, as well as other auxiliary equipment; the embedded processor is connected with the visible light camera, thermal camera and human-computer interaction equipment, and the visible light camera And the thermal camera is connected to the embedded processor through the FAKRA connector; the visible light camera is used to collect visible light image information, the thermal camera is used to collect thermal image information and temperature information, and the embedded processor uses face detection algorithm, face The pairing algorithm and the forehead temperature measurement algorithm process the data collected by the camera, and the human-computer interaction device displays and alarms the processed data.

[0030]The embedded processor uses a high-performance deep convolu...

Embodiment 2

[0032] This embodiment is based on the non-contact body temperature measurement system described in Embodiment 1, and specifically describes the measurement method of the system.

[0033] When the system measures body temperature, it first collects data through a visible light camera and a thermal camera, and performs face detection on the collected data. The visible light camera collects RGB images, that is, visible light images, and the thermal camera collects thermal images. Through the deep face detection algorithm, human faces are detected in visible light images and thermal images. The system uses the Nvidia Jetson-TX2 embedded processor for face detection. It takes about 75 milliseconds to detect a face in a visible light image with a resolution of 480x640, and it takes about 75 milliseconds to detect a face in a thermal image with a resolution of 320x240. 45ms, compared with the prior art face detection which takes about 100 milliseconds, the detection time of this me...

Abstract

The invention discloses a non-contact body temperature measurement method and system, and belongs to the technical field of temperature measurement. In order to solve the problems that in the prior art, infrared temperature measurement has large limitation on the measurement position and is not high in measurement accuracy, the invention provides a non-contact body temperature measurement method and system. The method comprises the steps: employing a visible light camera and a thermosensitive camera for data acquisition at the same time, and detecting the image data acquired by the cameras through a face detection algorithm; performing face matching on face data collected by the visible light camera and face data collected by the temperature-sensitive camera, reading a forehead temperatureset in combination with the range of the forehead, processing the forehead temperature data, and acquiring the final measured temperature, wherein the measurement result can be displayed or alarmed through human-computer interaction equipment. The system can realize long-distance non-contact body temperature measurement, is high in measurement accuracy and high in reliability, and is particularlysuitable for security check in public places such as stations and airports.

Description

technical field [0001] The present invention relates to the technical field of temperature measurement, in particular to a method and system for non-contact body temperature measurement. Background technique [0002] Coronavirus has been discovered in 1956, but people's current understanding of coronavirus is quite limited. It is currently known that the human body will develop fever and other respiratory symptoms after being infected with the coronavirus. Some coronaviruses are highly contagious and have the characteristics of human-to-human transmission. In just a few months, they will spread wildly and cause a large number of people to be infected. There is currently no effective treatment for many coronaviruses, and no related vaccines have been developed. Once a large-scale infection occurs, it will cause a large number of deaths and cause immeasurable losses to the economy. [0003] Fever is one of the main symptoms of coronavirus. Since most viruses are very contagi...
