摘要: 在建立了金属断口分析的计算机辅助测量计算系统的基础上,应用边缘提取、相关匹配点探测等图像处理技术,阐述了疲劳滑移带带宽、疲劳条纹线间距以及断口表面相对深度等测量计算方法。提出了以图像灰度为权函数的加权回归计算滑移线间距、滑移带带宽的方法;在金属断口表面相对深度的计算中,对Levine算法进行了有效的改进,使计算效率和测量精度都有了明显的改善和提高。
关键词 金属断口分析图像处理计算机辅助测量    
Abstract:On the base of establishment of a computer aided instrumentation and analysis system for analyzing metallic fracture surface, some methods in analysis of fracture surface, by means of computer graphics and image processing techniques for detecting of edges and corresponding points, are described in detail. A way based on the method of weighted least squares for measuring and calculating the sizes of fatigue slip band and fatigue striation spacing is presented. An improved Levine's algorithm of detecting a pair of corresponding points is proposed according to the principle of measuring distance from stereo vision , which is used in measuring the relative depth on metallic fracture surface so that the precision and efficiency of computations are all improved.
