根据实际工作测试需求，使用JAVA语言编制出可以测量数码图片上两点间距离及三点所在圆的直径；在此基础上计算出用鼠标在图片上绘出的任意图形面积以及其所占整个图片面积的百分比的工具软件，利用该软件可以大幅度提高分析金相数码照片的工作效率。%A program that can measure distance between two points and circle diameter formed by three points on digital picture is developed with JAVA language according to the actual detection need. Basing on this, a detection tool is developed for calculation of any picture area drawn with mouse as well as its percentage in the whole picture. Analysis efficiency of Metallographic digital photos can be improved substantially by utilizing this tool.
