Embodiment 1

[0027] First, refer to figure 1 An example electronic device 100 for implementing a temperature measuring method, device, electronic device, and computer-readable storage medium according to an embodiment of the present invention will be described.

[0028] Such as figure 1 Shown is a schematic structural diagram of an electronic device. The electronic device 100 includes one or more processors 102, one or more storage devices 104, an input device 106, an output device 108, and an image acquisition device 110. These components pass through a bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structure of the electronic device 100 shown are only exemplary, not limiting, and the electronic device may also have other components and structures as required.

[0029]The processor 102 can be implemented in at least one hardware form of a digital signal processor (DSP), a field programmable gate array (FPGA), ...

Embodiment 2

[0036] see figure 2 A schematic flow chart of a temperature measurement method is shown, the method mainly includes the following steps S202 to S210:

[0037] Step S202, acquiring an image frame pair containing the target object through the visible light camera and the thermal imaging camera; wherein, the image frame pair includes a visible light image and an infrared image collected at the same time; a black body is also set in the image acquisition area of ​​the thermal imaging camera.

[0038] Visible light is the part of the electromagnetic spectrum that can be perceived by the human eye. Generally, the wavelength of visible light is between 400 and 760nm. The visible light image acquired by the visible light camera is also the image that the human eye can see. The visible light image acquired by the visible light camera can intuitively reflect the The current state presented by the image collection area of ​​the visible light camera, such as presenting the position of th...

Embodiment 3

[0071] On the basis of the foregoing embodiments, this embodiment provides a specific example of applying the foregoing temperature measurement method, see image 3 The flow chart of another temperature measurement method is shown, the method mainly includes the following steps S302 to S314:

[0072] In step S302, the visible light image is collected by the visible light camera, the infrared image is collected by the infrared camera (that is, the aforementioned thermal imaging camera), and the position information and measured temperature of the person to be detected are determined based on the visible light image and the infrared image.

[0073] Step S304, input the infrared image into the black body detection model, determine the position information of the black body through the black body detection model and judge whether the black body is blocked. If yes, execute step S306, and if no, execute step S308. Specifically, a blackbody is set in the acquisition area of ​​the in...

Abstract

The invention provides a temperature measurement method and device, electronic equipment and a computer readable storage medium and relates to the field of artificial intelligence. The method comprises steps of obtaining an image frame pair (comprising a visible light image and an infrared image collected at the same time) containing a target object through a visible light camera and a thermal imaging camera; arranging a black body in an image acquisition area of the thermal imaging camera; determining a measurement temperature of the target object based on the image frame pair; performing black body detection of the infrared image to obtain the black body detection result (including the position information of the black body in the infrared image); determining the measurement temperatureof the black body based on the detection result of the black body and the infrared image; and correcting the measured temperature of the target object according to the measured temperature of the black body and the preset temperature of the black body, and taking the corrected temperature as the temperature measurement result of the target object. The method is advantaged in that accuracy of temperature measurement can be effectively improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a temperature measuring method, device, electronic equipment and computer-readable storage medium. Background technique [0002] After the outbreak of epidemics such as new coronary pneumonia and influenza, "fever" and "high temperature" have become one of the signals for screening suspected carriers. Existing temperature measurement equipment is roughly divided into three types, such as traditional mercury thermometers, handheld contact temperature measurement equipment, and infrared imaging temperature measurement equipment. In public places, in order to improve the convenience of temperature measurement, commonly used hand-held contact temperature measurement devices currently on the market, such as temperature guns, but temperature detection through temperature guns requires a lot of manual screening. In public places, it not only seriously affects the efficiency, but ...
