【摘要】 利用分层切片法重构金属断口宏观形貌,断口三维数据场可以提供全面的断口宏观形貌几何信息,从而对断口整体或局部区域进行定量可视化和测量。本文介绍了断口剖面轮廓线粗糙度、断口表面粗糙度、断口轮廓几何特征和断口宏观形貌局部区域的测量算法和定量分析方法。结果证实:通过断口三维空间数据场可以较精确地对断口宏观形貌几何特征进行定量分析,三维重构技术在断口形貌几何特征定量测量研究中具有一定的意义。更多还原

【Abstract】 3D data sets of fracture can supply all-round geometric information of macroscopical morphology of fracture by slicing method, and realize quantitative visualization and measurement for integral and partial fracture.This paper introduces measuring algorithm and quantitative analysis method for contour roughness of fracture section, roughness of fracture surface, geometric features of fracture contour and macroscopical morphology of fracture part.The results prove that geometric features of macroscopical morphology of fracture can be quantitatively analyzed accurately, and 3D reconstruction technique has certain significance in quantitative measurement of geometric features of fracture morphology.更多还原
