Abstract

The invention discloses an infrared human body temperature measurement method based on multi-dimensional compensation. The method comprises the following steps: acquiring an infrared image in a view field range through infrared thermal imaging equipment; acquiring a visible light image in a view field range through a camera; recognizing face areas in the infrared image and the visible light imagein the field range; mapping the face area of the infrared image in the view field range to the face area of the visible light image through a mapping relationship to obtain first temperature distribution data of each face in the view field range; compensating the first temperature distribution data through a multi-dimensional compensation algorithm to obtain second temperature distribution data; and respectively selecting several data with the highest temperature in the second temperature distribution data of each human face as the body temperature value of the human body corresponding to eachhuman face. Temperature data are compensated through a multi-dimensional compensation algorithm, the influence of parameters such as distance, target size, radiance and environment temperature on a temperature measurement result is reduced, and the precision of human face temperature measurement is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of infrared temperature measurement, in particular to an infrared human body temperature measurement method based on multidimensional compensation. Background technique [0002] Affected by the epidemic, more and more public places require body temperature screening when entering and exiting. Whether it is an airport, high-speed rail, subway, community, or office building, the demand for body temperature detection equipment is rising rapidly. Non-contact body temperature screening uses more infrared temperature measurement technology. All objects with a temperature higher than absolute zero are constantly emitting infrared radiation energy to the surrounding space. The size of the infrared radiation energy of an object and the distribution of its wavelength have a very close relationship with the surface temperature of the object. Therefore, by measuring the infrared energy radiated by the object itself, i...
