基于图像的建筑裂缝损伤特征自动评估方法

Automatic Evaluation Method for Damage Characteristics of Building Cracks by Computational Image Identification

采用计算机图像的识别技术,提出利用轮廓法对基于图像的建筑表面裂缝进行分割,然后对其损伤特征进行基于定量分析的自动评估方法进行研究,详细介绍了其运行过程及实现步骤。研究发现在既有建筑物宽裂缝与细小裂缝的图像识别中,均能比较准确地定量测量出裂缝的面积、长度和宽度特征。

The computer image recognition technology was adopted in this paper and the contour method was proposed to identify the image-based building surface cracks.An automatic evaluation method was developed to investigate for its damage characteristics.The implementation procedure was described in detail.It is found from this study that the proposed method could identify the image recognition for both wide and small cracks in exist buildings.The area,length,and width information of identified cracks can be accurately and quantitatively measured.
