An infrared imaging temperature measurement experimental device based on multi-scale feature fusion is designed for the temperature measurement of steel billets in metallurgical heating furnaces.Firstly,the overall structure of the temperature measurement system is designed based on the temperature measurement method and the application environment.Secondly,based on the system temperature measurement principle and temperature calibration experiments,the system temperature measurement model is derived and the mapping relationship between image grayscale and target temperature is established.Finally,for the recognition of billet targets,a semantic segmentation model based on multi-scale feature fusion is proposed to realize the effective recognition of billet targets.The results show that the temperature measurement system can achieve the measurement of billet surface temperature in the furnace,which meets the practical application requirements in metallurgical field.
