| 摘 要： | 裂缝是水泥混凝土桥梁的一种常见病害形式,基于图像的桥梁裂缝病害检测是实现桥梁数字化无损检测的一项新技术.为此,提出了一种基于图像连通域的桥梁裂缝提取方法,以实现从桥梁图像上准确识别裂缝,并提取其特征参数.针对水泥混凝土桥梁图像采集时,施工接缝、光照、污损、抖动等因素造成的干扰,主要分3个步骤实现裂缝目标的提取:(1)对... |

| Abstract: | Cracking is a normal form of cement concrete bridge defects.Image based bridge crack detection is a new technology to realize digital non-destructive test for bridge defects.A method for bridge cracks extraction based on image connected domain was proposed for recognizing and extracting the characteristic parameters of the cracks on the bridge surface.Three main steps of cracks extraction aimed at resolving the interference of construction joints,sunlight,defacements and vibration were performed:(1) the cra... |
| Keywords: | bridge engineering non-destructive test for bridge bridge cracks extraction measurement of connected domain |
