摘　　要：介绍一种基于无人机航拍的大桥桥索外观检测方法及其在武汉天兴洲长江大桥桥索聚乙烯(PE)保护套外观检测中的应用。根据桥梁结构特点和桥索分布形式设计一整套飞行检测方案,利用多轴旋翼无人机搭载的高清云台相机,批量密集地采集桥索的表观图像,通过图像处理提取有效信息,并依照现有相关规范对桥索的健康状况作出全面综合评价。无人机航拍较传统的人工吊篮或爬索机器人桥索检修技术具有简单高效、可操作性强等优点,能够高效、精准、全面地实现桥梁桥索的外观检测。This paper presents a practical application of the aerial photo technique using an unmanned aerial vehicle to inspect cable PE appearance in Tianxingzhou river bridge.First,we design a detail scheme including the flight and inspection based on the structural characteristics of the bridge and the distribution pattern of the bridge cables.Then,high-definition(HD)images of the cable PE appearance are acquired densely by the HD camera of the unmanned aerial vehicle.Finally,the working status and health condition of the bridge cable can be evaluated effectively by analyzing the acquired HD images.Compared to the traditional inspection techniques,such as the hanging basket and rope climbing robot,the aerial photo technique using unmanned aerial vehicle has advantages,including ease,effectiveness and strong maneuverability.
