Abstract

A method and device for infrared temperature measurement. Firstly, the obtained original infrared image is enlarged according to a preset magnification to obtain a second original infrared image, and each original pixel in the second original infrared image is divided to obtain multiple pixel group of pixels; then set the pixel at the preset position in each pixel group as the reference pixel; set the temperature of the reference pixel as the temperature of the original pixel corresponding to the reference pixel; The temperature of a target pixel; the target pixel is a pixel in the pixel group; finally, the temperature of the preset temperature detection point is obtained according to the temperature of multiple target pixels; the temperature detection point corresponds to multiple target pixels; The temperature method and device improve the resolution of infrared temperature measurement.

Description

technical field [0001] The invention relates to the field of temperature detection, in particular to an infrared temperature measurement method and device. Background technique [0002] The infrared thermal imager uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is consistent with the thermal image on the surface of the object corresponding to the distribution field. In layman's terms, an infrared thermal imaging camera converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors on the thermal image represent different temperatures of the measured object. [0003] Generally speaking, the composition of an infrared camera consists of four parts: 1) infrared lens: receive and converge the infrared radiation emitted by ...
