摘　　要：以电气火灾二次短路熔痕显微组织为例,利用显微图像各组元的灰度特性,运用数字图像技术中的图像滤波、图像分割、轮廓提取方法对显微组织图像进行预处理,获取图像晶格和孔洞。结合体视学方法,对显微组织晶格粒径、孔洞大小等几何特征参数进行计算分析与测量,探讨数字图像技术辅助二次短路熔痕金相组织进行定量分析技术方法。Taking the microstructure of secondary short circuit-caused melted trace in electrical fire for example, this paper introduced how to utilize the gray-scale characteristics of each constituent element in microscopic images with digital image technology, such as image filtering, image segmentation, contour extraction, to preprocess microstructure images and then get the separation figure of the lattice and holes. Based on the system composition and the stereoscopy method, the microstructure volume density, surface area density and other stereology parameters were analyzed and measured in the paper, and it is discussed which the quality analysis of the metallographie structure in secondary short circuit-caused melted trace in electrical fire with digital image technology.
