摘要
数字图像处理技术应用于裂缝测量可获取数字化的裂缝信息,具有操作灵活、测量精度高等优点,可以克服传统建筑裂缝测量技术的费时费力、精度不高等不足,具有广泛的应用前景。本文提出了一种基于区域生长法建筑裂缝识别方法,通过在实地拍摄的建筑裂缝图片中选择若干种子点,利用区域生长法提取出图像中的建筑裂缝部分,获得能够表征建筑裂缝特点的性质参数。结合工程实例进行实验,结果表明该法具有相当高的精确性和可行性,可以满足工程实际的需要。
Digital image processing applied to crack measurement can obtain crack digital parameters,with flexible operation and high measurement accuracy,can overcome the traditional building crack measurement technology of time and effort,lack of time-consuming laborious precision,has a wide range of application prospect. This paper proposes a construction fracture identification method based on regional growth method,by selecting several seed points from the pictures taken in the field of building cracks,and then region growing method is used to extract the image of structural cracks,then obtain parameters the characteristics of crack characterization of buildings. Experiment combined with engineering instance,the results show that the method has high accuracy and feasibility and can meet the requirement of engineering practice.
