摘　　要：沥青路面长时间暴露在自然环境下,并受车辆载荷影响,导致沥青路面出现不同形式的裂缝。沥青路面图像中的裂缝与周围的纹理相似,且背景复杂,容易造成裂缝与背景的混淆,且受室外环境中的光照和阴影变化的影响,导致提取结果不准确。为了提取得到裂缝区域的形态学特征,提出一种多孔隙沥青路面裂缝形态学特征自动提取方法。在对沥青路面图像展开形态学处理、光照非均匀校正、灰度化处理等一系列预处理操作后,利用模糊C均值算法对其分割,使裂缝区域特征得到突出展示;将裂缝分为单个一般裂缝、弯曲裂缝和分岔裂缝三种,经过线性拟合后,得到三种裂缝的形态学特征。实验结果表明,所提方法可以精准提取到沥青路面图像的形态学特征,且不会影响图像质量。If asphalt pavement is exposed to natural environments for a long time and is affected by vehicle loads,different forms of cracks will be formed on the asphalt pavement.Generally,cracks in asphalt pavement images are very similar to the surrounding textures,and the image background is complex,which can easily cause confusion between cracks and background.The extraction results are often inaccurate due to changes in lighting and shadows in outdoor environments.In order to extract morphological features of crack regions,this article presented an automatic method for extracting morphological features of cracks in porous asphalt pavement.After performing a series of preprocessing operations such as morphological processing,non-uniform lighting correction,and grayscale processing on the asphalt pavement image,we used the fuzzy C-means algorithm to segment the image,thus highlighting the features of the crack regions.And then,we divided these cracks into three types:single general cracks,bending cracks,and bifurcated cracks.After linear fitting,we obtained the morphological characteristics of the three types of cracks.Experimental results prove that the proposed method can accurately extract the morphological features of asphalt pavement images without affecting image quality.
