Because infrared temperature measurement techniques are limited by some factors such as environment, applications and the characteristics of material itself, some novel noncontact temperature measurement methods have attention gradually. However, their simple analysis functions are not sufficient to meet the demands for wide usage. Among them, the static infrared image analysis is not able to solve more complex problems. For this reason, an infrared video temperature measurement method is proposed. The method is based on MFC. Its programming is completed by calling the OpenCV library. In the method, many functions such as point, line,and surface analysis and automatic high temperature point capturing can be implemented. The highest and lowest temperature analysis functions and the online highest and lowest temperature capturing functions are creatively added in the line and surface analysis. The experimental result shows that this method has the advantages of obvious dynamic analysis effectiveness, stable software running and higher temperature measurement precision.
