Temperature measurement method, device and system based on infrared imaging and medium

Abstract

The invention relates to a temperature measurement method, device and system based on infrared imaging and a medium. The method comprises the steps of obtaining a target image of a target person when the target person is detected to enter a detection range; inputting the target image into a trained network model to obtain result information, the result information being used for representing whether the target image contains a complete forehead image, the complete forehead image being a part of the target image, and the complete forehead image being used for representing that the forehead of the target person is not shielded; when the target image does not contain the complete forehead image, outputting first prompt information, and the first prompt information being used for prompting the target person to correct the crown; obtaining a correct image, determining a complete forehead image based on the correct image, and the correct image being a thermal infrared image containing the complete forehead image; and determining temperature information based on the complete forehead image, wherein the temperature information is used for representing the forehead surface temperature of the target person. According to the invention, the effect of improving the temperature measurement accuracy is achieved, and then the epidemic prevention effect is improved.

Description

technical field [0001] The present application relates to the field of infrared imaging temperature measurement, in particular to a temperature measurement method, device, system and medium based on infrared imaging. Background technique [0002] Due to the existence of black body radiation, any object radiates electromagnetic waves according to the temperature; the part with a wavelength of 2.0~1000 microns is called infrared; thermal infrared imaging uses a thermal infrared camera sensitive to thermal infrared to image objects, which can reflect The temperature field on the surface of the object to achieve temperature measurement; [0003] At this stage, in response to the call for strict epidemic prevention, some public places generally choose to set up thermal infrared temperature monitors at the entrances to measure the temperature of people passing by, so as to achieve accurate epidemic prevention; existing thermal infrared temperature monitors are generally used to mo...

Problems solved by technology

[0003] At this stage, in response to the call for strict epidemic prevention, some public places generally choose to set up thermal infrared temperature monitors at the entrances to measure the temperature of people passing by, so as to achieve accurate epidemic prevention; existing thermal infrared temperature monitors are generally used to monitor The temperature of the forehead of the people who come and go is tested. If the supervisors are not paying attention at this time, some people whose foreheads are covered due to irregular clothes will be directly measured, which will lead to inaccurate temperature measurement results, which will affect the effectiveness of epidemic prevention. bad
