Abstract

The invention discloses a visible light temperature measurement method based on infrared target detection. The method mainly includes the steps of depicting a virtual thermal radiation image of a measured scene by using the infrared remote sensing technology, and then capturing the same scene to form a color image by using the visible light remote sensing technology; performing a series of processing such as filtering, edge outline trimming, stretching, scaling and cropping to make the imaging of each thing in the scene in the infrared image and the visible light image perfectly overlap proportionally; selecting a measured target object of interest in the visible light image by using a cursor and extracting coordinates of the measured object; and then calculating, through the infrared andvisible light image coordinate conversion formula, coordinates of the measured object in the infrared image, finally calculating the temperature of a measuring point by using a Planck radiation formula and performing superimposition onto the visible light image. In this way, the temperature measurement can be performed on any measured object of interest on the visible light image in a very simpleand direct manner.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to a visible light temperature measurement method based on infrared target detection. Background technique [0002] Due to the limitations of the infrared detector's own physical characteristics, spatial resolution and other factors, a single thermal imaging image can often only highlight the measured objects with large temperature differences or physical volumes in the scene, while some are small in size, densely distributed and highly recognizable. The measured objects that are not high but happen to be of interest to people are often displayed vaguely, making it difficult for people to accurately locate and extract the temperature of this type of measured object of interest intuitively. [0003] Based on the above problems, this solution proposes a visible light temperature measurement method based on infrared target detection, which can quickly and accurately mea...
