In this paper, a new method of parameter measurement of thermal metal interfacial tension based on image processing technology is introduced. The images of metal samples at different temperatures are automatically and continuously measured by the computer camera system. With advanced edge detection algorithm and least square coincidence Close analysis of its long axis, short axis and wetting angle, and thus calculate the surface tension. The hardware structure and software features of the system are described. The experimental results are satisfactory. The measured parameters have high accuracy with error less than 1%.
