混凝土结构的物理、化学和力学损伤分析 机械曝光需要应用创新的无损检测 能够追踪微结构的空间变化的方法。在这里，实用程序 三种不同的裂纹检测方法在计算机断层图像分析中的应用 对各种胶凝建材进行了评价。由于缺乏参考文献 样本和标准化的图像质量评价程序，结果如下 与手动分割的参考数据集相比。一个具体的问题是如何 自动裂纹检测可用于定量表征 破坏过程，如裂纹长度和体积。裂纹检测方法 已经集成到一个科学可视化系统中，该系统允许显示 断层扫描图像以及呈现结果。
Analyzing damages at concrete structures due to physical, chemical, and mechanical exposures need the application of innovative non-destructive testing methods that are able to trace spatial changes of microstructures. Here, the utility of three different crack detection methods for the analysis of computed tomograms of various cementitious building materials is evaluated. Due to the lack of reference samples and standardized image quality evaluation procedures, the results are compared with manually segmented reference data sets. A specific question is how automatic crack detection can be used for the quantitative characterization of damage processes, such as crack length and volume. The crack detection methods have been integrated into a scientific visualization system that allows displaying the tomography images as well as presenting the results.
