中文摘要：

路面裂缝是道路病害的主要表现,在路面裂缝的检测过程中,为了准确、详细记录路面裂缝信息,需要对裂缝病害的形态特征进行分析,针对这一问题,提出了道路病害形态特征的图像分析方法.首先,对提取后的路面裂缝进行膨胀处理,连接断裂的裂缝;然后通过细化处理,得到具有单像素宽裂缝的裂缝骨架;最后采用游码和链码统计裂缝的像素数目和几何形态特征,实现对路面裂缝的特征参数值获取及量化描述.结果表明该裂缝图像分析方法对道路裂缝形态特征的描述和统计有效,具有实用价值.

英文摘要：

Pavement cracks are main forms of road diseases.To record the detail information of road cracks accurately,it is necessary to analyze morphological characteristics of pavement cracks in the process of detecting cracks.Aimed at this problem,an evaluation method for road cracks morphological characteristics was proposed.Firstly,disconnect portions in the images of cracks extracted were connected by the operation of dilation.Then,the images with single pixel width cracks were obtained by the thinning processing.Finally,tour code and chain code were used to count the number of pixels and morphological characteristics of pavement cracks.Experimental result shows that the proposed evaluation method in this paper is effective to describe the morphology characteristics of crack,having practical value.
