在数字图像处理技术应用于温度非接触式测量原理研究的基础上,建立目标物辐射图像灰度值有关物体温度和辐射波长的函数关系式.基于MATLAB软件平台和热辐射原理和光学成像原理,运用GUI编程设计了一套碳钢热处理温度非接触式测量系统,实现对加热工件温度的非接触测量,该系统可实时完成对目标物图像采集存储和处理,并同时完成温度和误差计算,实验表明,该系统可实时测量高温工件温度,动态响应好,热惯性低,抗干扰性和精度较高.
Based on a research of the application of the non‐contact temperature measuring principle to dig‐ital 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 real‐time measurement of the temperature of heat workpieces with good dynamic response ,low thermal iner‐tia ,anti‐interference and high precision ,w hich satisfies the requirement of industrial application .
