Abstract

It is critically important to plan properly for integrating and deploying unmanned aerial vehicles (UAVs) in the bridge inspection process, there is a need for tools to support implementation and decision-making regarding the use of UAVs at specific structures. In this study, a resource estimation tool that can be used to estimate the resources required for UAV-assisted bridge inspections is developed. The tool can aid inspectors in determining the estimated flight time and resources required for using a specific UAV and operator during the inspection of a specific bridge. The tool supports the development of optimal flight paths based on the structural geometry and positioning of structural elements of a bridge, establishes a range of recommended flight speeds for conducting reliable UAV-assisted bridge inspections based on the skill level(s) of the pilot(s) who were involved in conducting inspections. The developed tool also establishes a recommended range of wind speed and the corresponding standoff clearance information for safely conducting UAV-assisted bridge inspections. The tool also provides an estimated number of batteries required to allow the estimated required flight time. In this paper, the development of the tool is described, and the advantages of the tool are illustrated by its application in a case study involving a 10-span steel continuous multi-beam bridge with a reinforced concrete deck. The tool is developed as a spreadsheet and is publicly available through a GitHub page, accessible at https://github.com/ACCESSLab/Resource-Assessment-Tool-for-Effective-UAV-Assisted-Bridge-Inspection .
无人机辅助桥梁有效检测的资源评估工具
在桥梁检测过程中适当规划和部署无人机(UAV)至关重要,因此需要一些工具来支持在特定结构中使用无人机的实施和决策。本研究开发了一种资源估算工具,可用于估算无人机辅助桥梁检测所需的资源。该工具可帮助检查员确定在检查特定桥梁时使用特定无人机和操作员所需的预计飞行时间和资源。该工具支持根据桥梁结构的几何形状和结构元素的定位制定最佳飞行路径,并根据参与检查的飞行员的技能水平,为进行可靠的无人机辅助桥梁检查确定推荐的飞行速度范围。开发的工具还为安全进行无人机辅助桥梁检测确定了推荐的风速范围和相应的间距信息。该工具还提供了估计所需飞行时间所需的电池数量。本文介绍了该工具的开发过程,并通过对一座 10 跨钢筋混凝土桥面连续多梁桥的案例研究,说明了该工具的优势。该工具以电子表格的形式开发,并通过 GitHub 页面公开,访问网址为 https://github.com/ACCESSLab/Resource-Assessment-Tool-for-Effective-UAV-Assisted-Bridge-Inspection。
