Abstract: Starting from the theory of infrared thermal imaging temperature measurement and combining with the characteristics of wearable intelligent terminals, an infrared thermal imaging temperature measurement system based on intelligent safety helmet is designed. The components of the system are introduced in detail, and the temperature measurement module software and the corresponding algorithm are analyzed emphatically. Through the calibration method of the target radiation source, the corresponding relationship between thermal imaging and temperature is established, and the temperature of the target can be measured by moving the position of the intelligent safety helmet worn. The experimental test shows that although the temperature of the target to be measured is different, the attenuation trend is generally the same when the distance increases, and the attenuation degree is relatively small. Therefore, the system has a relatively high application value in the temperature measurement of a relatively short distance.
