摘要： 混凝土路面的裂缝检测是确保道路安全的重要基础任务。针对混凝土路面的复杂背景和裂缝本身复杂的拓扑结构,提出了一种基于空洞卷积和多特征融合的混凝土路面裂缝检测网络,该网络采用基于U-Net的编码-解码结构。在编码阶段,使用改进的残差网络Res2Net提高特征提取能力;在网络的中间部分,使用串联和并联相结合的不同空洞率的空洞卷积,从而在增加特征点的感受野的同时不会降低特征图的分辨率;在解码阶段,融合了从低层卷积到高层卷积的多尺度和多级特征,提高了裂缝检测的准确性。为证明所提算法的有效性和准确性,将其与现有的部分检测方法进行了比较并使用F-score来评估检测性能。在多个混凝土路面数据集上的实验结果表明,该算法提高了裂缝检测的准确性,具有较好的鲁棒性。
