针对避雷针长期露天运行中易产生缺陷的难题,设计了一种专用于避雷针缺陷视觉检测的攀爬机器人.在机械结构方面,机器人采用基于力放大结构的夹持机构,利用机械增益效应显著提升附着稳定性,在自重仅40kg的条件下实现50kg的负载能力,从而确保高处作业的安全和可靠性.在视觉算法方面,机器人集成了基于密度的噪声应用空间聚类(Density-Based Spatial Clustering of Applications with Noise,DBSCAN)算法的视觉检测系统,通过高分辨率工业相机采集避雷针表面图像,利用稀疏重构方法增强缺陷特征响应,再结合DBSCAN算法实现对孔洞、裂纹等不规则缺陷的精准识别.实验结果表明,该机器人能够在避雷针上实现稳定攀爬和精确定位,其视觉系统能高效检测多类型表面缺陷,为高空电力设施的智能化检测提供了新的技术途径.
To address the problem that lightning rods are prone to defects during long-term outdoor operation,a climbing robot specifically for the visual defect detection of lightning rods is designed.In terms of mechanical structure,the robot adopts a clamping mechanism based on a force amplification structure,which utilizes the mechanical gain effect to significantly improve adhesion stability,achieving a payload capacity of 50 kg with a self-weight of only 40 kg,thereby ensuring the safety and reliability of high-altitude operations.In terms of visu-al algorithms,the robot integrates a visual detection system based on the density-based spatial clustering of ap-plications with noise(DBSCAN)algorithm.It captures images of the lightning rod surface using a high-resolu-tion industrial camera,utilizes a sparse reconstruction method to enhance the defect feature response,and then combines the DBSCAN algorithm to achieve accurate recognition of irregular defects such as holes and cracks.Experimental results demonstrate that the robot can achieve stable climbing and precise positioning on lightning rods,whose visual system can efficiently detect various types of surface defects,providing a new technical ap-proach for the intelligent inspection of high-altitude power facilities.
