Abstract

The invention provides a temperature measurement method based on an infrared thermal imaging technology, which comprises the following steps of: 1, measuring black body radiation by using an infraredthermal imaging machine core to obtain gray value data; 2, establishing a temperature measurement model, reading gray value data, and obtaining model parameters by using a fitting tool; 3, substituting a large amount of gray value data at different temperatures into the temperature measurement model in the step 2, and verifying the accuracy and precision of the model; 4, optimizing the model according to a verification result; and 5, outputting the model in the step 4 to obtain an optimal temperature measurement model. The temperature measurement method based on the infrared thermal imaging technology can adapt to changes of various environment temperatures, the infrared imaging technology is not affected by heavy fog, haze and other weather, and the adaptability and accuracy of temperature measurement are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of infrared thermal imaging temperature measurement, and in particular relates to a temperature measurement method based on infrared thermal imaging technology. Background technique [0002] Infrared thermal imaging technology is a technology that receives the infrared radiation emitted by the measured target at a certain distance through the infrared sensor, and then transforms it into a video thermal image of the target by the signal processing system. It converts the thermal distribution of the object into a visible image. , and displayed on the monitor in gray scale or false color, so as to obtain the temperature distribution field of the measured target. Infrared thermal imaging temperature measurement technology is a non-contact temperature measurement. Because of its fast response speed, no damage to the temperature field of the measured object, and the ability to detect some difficult-to-reach or for...
