为了提高公路路面裂缝的检测效率,采用图像处理技术对路面裂缝进行自动识别,提取裂缝参数.采集到裂缝图像之后进行灰度化、去噪、阈值分割处理检测出路面裂缝,对线性裂缝提取骨架并细化求出其长度和平均宽度,对于网状裂缝通过其外接矩形的面积计算出破损面积.实例验证这种方法能够有效检测裂缝宽度,相对误差较小.%In order to improve the road pavement crack detection efficiency,it applies the image processing technology to automatically identify pavement cracks,extracts the fracture parameters.This method includes graying,de-noising,threshold segmentation process and detecting surface cracks,defining the skeleton from the linear crack and the length,and average width.For the mesh crack,it calculates the damaged area from the area of the circumscribed rectangle.Examples of test show that the method can effectively detect the crack width and decrease the relative errorl.
