| 摘 要： | 针对图谱划分理论与路面裂缝的特点，提出了一种基于图论的路面裂缝分割方法，该方法将图像作为一个带权图进行分析．建立节点之间的位置距离和灰度差异的能量函数，函数的最小值作为路面裂缝检测的最优分组．通过实验与传统方法最大类间方差法、领域差异直方图法相比，此方法能较好的检测出大于1mm的路面裂缝．

| Abstract: | With the theory of graph cut and the characteristic of pavement crack, a method for segmentation of pavement crack based on graph theory was proposed. The graph regarded as weighted graph was analyzed in the method. An energy function was established according to the distance and gray-scale differences between nodes. The minimum of function corresponds to an optimal group of detection. By experiment and comparing with the existing method such as OTSU （Maximum Variance Between Clusters） ,NDHM （Neigboring Difference Histogram Method）, the proposed method is better to detect the pavement crack which is larger than 1 mm. |
