【Abstract】 Based on a research of the application of the non-contact temperature measuring principle to digital image processing,the paper establishes a functional formula of the target radiation image grey values on temperature and radiation wavelengths.Based on MATLAB software platform and the principles of thermal radiation and optical imaging,the paper designs a set of non-contact measuring system of carbon steel heat treatment temperature by GUI programming for the non-contact measurement of the heating temperature of workpieces.The system can finish real-time image collection,storage and processing with temperature and error calculation at the same time.Experimental results show that the system can do realtime measurement of the temperature of heat workpieces with good dynamic response,low thermal inertia,anti-interference and high precision,which satisfies the requirement of industrial application.更多还原
