无人机在桥梁检测应用中的若干问题探讨

Discussion about UAV Technique application in Bridge Detection

运用无人机技术进行桥梁检测,具有灵活便捷、高效、经济效益显著等特征。然而,目前国内外大多数学者均在理想状态下开展相关技术试验,甚至将其优势言过其实。为了客观认识其应用水平,在查阅大量文献的基础上,分别从研究现状、相关硬件装备技术性能要求以及应用特点三方面展开探讨。研究结果认为,无人机飞行器的定位信号、安全性、结构设计以及图像识别问题是影响其广泛应用的技术“瓶颈”,并基此探讨了其改善措施。

The application of UAV technology in bridge detection has a feature of flexibility,convenience,high efficiency and remarkable economic benefits.However,most domestic and foreign scholars have carried out the test under the perfect condition,and even overstated its advantages at present.In order to objectively understand its technical level,based on consulting a large number of literatures,this paper from three aspects:research status,technical performance requirements of related hardware equipment and application characteristics elaborates.The results show that UAV positioning signal,safety,structural design and image recognition problems are the key technology"bottleneck"affecting its wide application,In addition the improvement measures are discussed.
