| 摘 要： | 针对远距离拍摄的混凝土结构表面裂缝,采用灰值化、图像增强、阈值分割、腐蚀、膨胀、边界跟踪等数字图像处理算法,设计了一套提取裂缝特征信息的系统,实现对宽度和长度特征的测量。结果表明,这一裂缝特征测量方法具有可行性和精确性的特点,为已有建筑物结构裂缝的确认与分析提供了一条新的途径。

| Abstract: | Based on images of concrete surface cracks which was a long-distance shot,some special image processing algorithm,such as image graying,image enhancement,image segmentation,dilation,erosion and boundary tracking,were used to obtain the cracks length and width,and one software was developed.The results show that this method of cracks length and width measurement has some features of feasibility and accuracy,and the development presented may provide a new technique for the determination and analysis of struct... |
