摘要
针对金相分析时,不同物镜下得到的不同放大倍数显微图片无法定量评估其实际长度的问题,使用C++ Builder开发了一套图片定标系统。该系统采用鼠标的三个事件MouseDown、_MouseMove、_MouseUp进行标准直径所占像素的测定,得出相应定标系数,并以Tlmege和Tcanvas部件相关函数完成图片线段长度及采集日期等的标注,从而实现了图片的定标。
Aiming at the problem that the actual length of micro-graph is difficult to be measured because of different objective lens with different amplified times in analyzing metallographic, the marking picture system is developed with C++ Builder in this paper. The pixels of standard diameter are measured by MouseDown, MouseMove, MouseUp of mouse in the system, and then the marking picture coefficient is obtained. The length of the line in the picture is marked by using function Timage and Tcanvas ect. and so marking picture is realized.
