摘要: 利用MATLAB软件对采集到的混凝土表面裂缝RGB图像进行灰度化、滤波及分割处理后得到二值灰度图像,再进行裂缝判断和片段连接处理,计算混凝土结构表面裂缝的面积、长度及最大宽度等参数,研制了基于数字图像的混凝土结构表面裂缝识别程序——IPCW;以某混凝土坝工程浅表性裂缝识别实例对IPCW进行了验证。结果表明:IPCW识别的裂缝宽度值与实测值的相对误差总体在11%以内,识别精度满足工程要求;IPCW对大范围搜索裂缝具有较大优势,可应用于土木工程结构的裂缝初查。

Abstract: The acquired RGB image of concrete surface crack was grayed, filtered and segmented by MATLAB software to obtain a binary grayscale image. Then, crack judgment and segment connection processing were carried out. The crack area, length, maximum width and other parameters of concrete structure surface were calculated. A digital-image-based recognition program for surface cracks of concrete structures—IPCW was developed. The IPCW was verified by an example of shallow surface crack identification in a concrete dam project. The research indicates that the relative error between the crack width value identified by IPCW and the measured value is generally within 11%, and the identification accuracy meets the engineering requirements. IPCW has great advantages in searching for cracks in a wide range and can be applied to the preliminary inspection of cracks in civil engineering.
