| Abstract: | It is found that, during learning the course of metallographic technology and experiments, students have been confused with the digital image frequently, and they are also lack of computer processing technology for metallographic structure photo. In this paper, the important conceptions related to the digital image have been introduced firstly. Then, the relationship between the size of metallographic structure photo and the viewing fields when taking photo using digital camera has been analyzed in detail. It is also introduced how to use the digital image in the Word processing software properly. After that, the main applications of the digital-image-processing technology on the analysis of metallographic structure has been introduced. Especially, the application of the MATLAB image processing toolbox was introduce. An example for the analysis of second phase in microstructure has been shown in this paper, and the result is consistent with that analyzed by professional software imagepro. |
