Problems solved by technology

This will cause the thermal infrared detector to receive different thermal radiation values, so the acquired thermal infrared temperature shows fluctuations
[0006] The traditional method is difficult to locate the moving target, mainly relying on manual selection of the best attitude frame, manually delineating the area of ​​interest to obtain the temperature measurement results, this method is labor-intensive and affected by human factors, and cannot achieve long-term automatic monitoring

Abstract

An embodiment of the present invention provides a method and system for detecting the highest temperature of a moving target, including: acquiring a thermal infrared video of a moving target, segmenting any frame of image, and obtaining several connected domains. The area of ​​the connected domain is the largest, and any frame image is used as an effective frame image; several temperature characteristic parameters of each effective frame image are obtained, and the histogram of each temperature characteristic parameter is obtained, and the frame corresponding to the maximum value of each histogram is used as a comparison frame. Excellent frame image; obtain the number of repetitions of each optimal frame image in all the optimal frame images, and use the first 6 frame images with the largest number of repetitions as the alternative optimal frame image; from all the alternative optimal frame images Three images are selected as the optimal frame images, and the maximum temperature of the moving target is obtained according to the three optimal frame images. The invention realizes the automatic detection of the thermal infrared temperature of the moving target without manual intervention and is not affected by human factors.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for detecting the highest temperature of a moving target. Background technique [0002] Temperature is a common physical quantity to be detected. Common surface temperature detection methods include infrared cameras, contact thermocouples, body surface thermometers and contact chips. Among them, the latter three methods obtain the temperature of one point, which are prone to measurement errors and are only suitable for short-term detection of a small number of samples. Infrared thermal imager temperature measurement has the advantages of being non-invasive and presenting temperature distribution. It can obtain the temperature distribution of the area of ​​interest, obtain more temperature information, and realize online temperature measurement. The use of thermal imagers for online temperature monitoring has a wide range of application requirements in the f...
