【摘要】 计算机金相图像处理是材料科学的一个研究领域。专用金相图像处理软件由于价格昂贵,硬件上实现复杂,在很大程度上不能满足生产、教学、科研工作的需要。本文利用现有硬件设备,以Word 2000为平台,构建了一套基于Microsoft Office的金相图像采集、处理、分析系统。图像采集方面,利用Office中的“插入”菜单,通过CMOS摄像头直接对金相显微镜的成像进行捕捉,把金相图像保存为数字图像文件,并插入到Word中.这种图像采集方法最大的优点是不需要照相和洗相等一些繁琐的程序。图像处理方面,利用Office中的“图片”工具栏和Photo Editor两个图像处理工具,可以很方便地对图像进行灰度、黑白模式的转换,可以对图像的大小、方向、亮度、对比度及平滑等进行处理。通过处理,可以达到令人满意的去噪效果,大大地提高图像的质量。金相分析方面,利用Word2000绘制出需要的测试线,并经实际尺寸的标定后,可以在Word 2000和Photo Editor中对金相组织的一维和二维基本参数进行测量,利用体视学的基本公式和Excel 2000,可以很方便的进行显微组织的定量测量与分析。基于Office2000的金相图像处理与分析系统可以用于生产检测和教学科研,特别是中、小企业或产品单一的冶炼、铸造、轧钢企业。它大大地缩短了金相图像获取的时间,减少了技术劳动,提高了效率和准确度。更多还原

【Abstract】 Metallographic analysis technology is an important measure used in current material research. Because the high price and the complex hardware requirements, the software specially used in metallographic processes can not satisfy the need in production, teaching, scientific research in very great degree. Making use of Word 2000 as the platform, this paper built a metallographic process, collecting and analysis system based on the Microsoft Office software. Capture of an image is achieved through CMOS camera by using the insertion menu in Office, and then it can be saved as a digital image, or inserted in Word.Image can be transformed to black and white pattern or gradient pattern very conveniently by using the picture tool fence in Office or the imagery processing tools in Photo Editor. Parameters such as size, direction, brightness, the contrast and smooth of the image are all can be processed though this method. A satisfying denoise result can be achieved, and the image quality can be greatly enhanced through image treatment.Based on the test lines, the one-dimensional and two-dimensional parameter about the metallographic structure can be measured in Word 2000 and Photo Editor after the actual dimensions demarcated. The structure can be quantitatively analyzed correspondingly.Metallographic process and analysis system based on the MS Office software can be used in examination, teaching and scientific research, especially in medium, small enterprise engaged in melting, casting and steel rolling. It greatly reduced the time used in gaining the metallographic, reduced the technical work, enhanced the efficiency and the accuracy.更多还原
