Deterioration of bridge infrastructure is a serious concern to transport and government agencies as it declines serviceability and reliability of bridges and jeopardizes public safety. Maintenance and rehabilitation needs of bridge infrastructure are periodically monitored and assessed, typically every two years. Existing inspection techniques, such as visual inspection, are time-consuming, subjective, and often incomplete. Non-destructive testing (NDT) using Unmanned Aerial Vehicles (UAVs) have been gaining momentum for bridge monitoring in the recent years, particularly due to enhanced accessibility and cost efficiency, deterrence of traffic closure, and improved safety during inspection. The primary objective of this study is to conduct a comprehensive review of the application of UAVs in bridge condition monitoring, used in conjunction with remote sensing technologies. Remote sensing technologies such as visual imagery, infrared thermography, LiDAR, and other sensors, integrated with UAVs for data acquisition are analyzed in depth. This study compiled sixty-five journal and conference papers published in the last two decades scrutinizing NDT-based UAV systems. In addition to comparison of stand-alone and integrated NDT-UAV methods, the facilitation of bridge inspection using UAVs is thoroughly discussed in the present article in terms of ease of use, accuracy, cost-efficiency, employed data collection tools, and simulation platforms. Additionally, challenges and future perspectives of the reviewed UAV-NDT technologies are highlighted.

基于无人机的桥梁状况评估应用

桥梁基础设施的恶化是运输和政府机构的严重关切,因为它降低了桥梁的可维护性和可靠性,并危及公共安全。桥梁基础设施的维护和修复需求定期(通常每两年)进行监视和评估。现有的检查技术(例如外观检查)非常耗时,主观,而且常常不完整。近年来,使用无人飞行器(UAV)进行的无损检测(NDT)在桥梁监控方面获得了发展的动力,特别是由于提高了可达性和成本效率,交通阻塞的威慑力以及检查过程中的安全性得到了提高。这项研究的主要目的是对无人机在桥梁状态监测中的应用进行全面的回顾,与遥感技术结合使用。深入分析了视觉技术,视觉图像,红外热像仪,LiDAR和其他与UAV集成在一起以进行数据采集的传感器。这项研究汇编了过去二十年来发表的65篇期刊和会议论文,详细审查了基于NDT的无人机系统。除了比较独立的和集成的NDT-UAV方法外,本文还从易用性,准确性,成本效益,使用的数据收集工具和仿真平台的角度,全面讨论了使用无人机进行桥梁检查的便利性。 。此外,重点介绍了已审查的无人机-无损检测技术的挑战和未来前景。深入分析了与无人机集成在一起以进行数据采集的方法。这项研究汇编了过去二十年来发表的65篇期刊和会议论文,详细审查了基于NDT的无人机系统。除了比较独立的和集成的NDT-UAV方法外,本文还从易用性,准确性,成本效益,使用的数据收集工具和仿真平台的角度,全面讨论了使用无人机进行桥梁检查的便利性。 。此外,重点介绍了已审查的无人机-无损检测技术的挑战和未来前景。深入分析了与无人机集成在一起以进行数据采集的方法。这项研究汇编了过去二十年来发表的65篇期刊和会议论文,详细审查了基于NDT的无人机系统。除了比较独立的和集成的NDT-UAV方法外,本文还从易用性,准确性,成本效益,使用的数据收集工具和仿真平台的角度,全面讨论了使用无人机进行桥梁检查的便利性。 。此外,重点介绍了已审查的无人机-无损检测技术的挑战和未来前景。本文在易用性,准确性,成本效益,使用的数据收集工具和仿真平台等方面对使用无人机进行桥梁检查的便利性进行了全面讨论。此外,重点介绍了已审查的无人机-无损检测技术的挑战和未来前景。本文在易用性,准确性,成本效益,使用的数据收集工具和仿真平台等方面对使用无人机进行桥梁检查的便利性进行了全面讨论。此外,重点介绍了已审查的无人机-无损检测技术的挑战和未来前景。
