Research on pavement crack identification method based on median contrast filtering and connected domain marking

提出了一种基于新型滤波和连通域标记处理的路面裂缝识别方法,利用中值反差滤波对路面病害状况采集信息图进行过滤,保留路面裂缝病害信息,然后利用连通域标记方法、图像处理中的腐蚀、膨胀运算提取路面裂缝信息,可避免传统算法中繁琐的噪声消除操作,使整个处理过程更加简易。

This paper proposes a method on pavement crack identification method based on novel filtering and connected domain marking.In this method,the median contrast filter is used to filter the information graph of pavement diseases,and the information of pavement cracks is retained.Then,the information of pavement cracks is extracted by using the connected domain marking method,the corrosion and expansion operation in image processing.This method can avoid the tedious noise elimination operation in the traditional algorithm and make the whole process easier and clearer.
