Problems solved by technology

[0003] Traditional infrared detectors require the temperature measurement sample to be measured in a small specific area. If the area is not limited, when the measured sample moves, the distance between the measured sample and the temperature measurement equipment changes, and the temperature measurement The results will also change accordingly, and the temperature measurement results will have a large error
And limiting a small temperature measurement area will have a great impact on the detection efficiency
Solving the problem of the influence of distance changes on the temperature measurement results when the measured sample moves becomes the key to improving detection efficiency

Abstract

The invention discloses a temperature measurement method based on automatic identification, which includes: obtaining infrared images of training samples, and recording the distance between the training samples and infrared imaging equipment; Designate the area, and count the number of pixels occupied by the preset shape frame; calculate the relationship between the distance and the number of pixels occupied by the preset shape frame; obtain the infrared image of the sample to be tested, and use the preset shape frame to select the Measure the specified area in the infrared image of the sample, and count the number of pixels occupied by the frame of the preset shape; calculate the distance between the sample to be tested and the infrared imaging device according to the relationship between the distance and the number of pixels occupied by the frame of the preset shape Distance: according to the distance between the sample to be tested and the infrared imaging device, temperature compensation is performed on the detection temperature of the sample to be tested detected by the infrared imaging device. The invention solves the problem that the distance change affects the temperature measurement result when the sample to be tested moves.

Description

technical field [0001] The invention relates to the field of signal control processing. More specifically, the present invention relates to a temperature measurement method and system based on automatic identification. Background technique [0002] Infrared temperature measurement is to receive the infrared radiation emitted by people or objects through the infrared detector, and convert it into an image by the signal processing system. It can convert the temperature into gray scale, and use the gray scale to reflect the temperature of people or objects. Push to get the temperature information of people or objects. [0003] Traditional infrared detectors require the temperature measurement sample to be measured in a small specific area. If the area is not limited, when the measured sample moves, the distance between the measured sample and the temperature measurement equipment changes, and the temperature measurement The result will also change accordingly, and the tempera...
