摘要
针对光伏巡检效率低下、定位精度差、巡检容易遗漏、自动化程度低的问题,本文提出了一种依据地面标志物的无人机光伏巡检的高效方法。首先规划了无人机巡检系统的整体实现方案,接着设计了独特的三角地面标志物,通过特征匹配技术对标志物进行目标识别,以此校正无人机的初始位置和方向,然后根据全局阈值法与电池板特征,进行图像分割并提取出巡检路径,最后设计了无人机巡检过程中的转向和停止策略。实验结果表明本巡检系统满足高精度高效光伏巡检要求。
This paper proposes an efficient method of photovoltaic inspection of UAV Based on ground markers aiming at the problems of low efficiency,poor positioning accuracy,easy omission and low automation of photovoltaic inspection.Firstly,the overall implementation scheme of UAV inspection system is planned,then a unique triangular ground marker is designed,which is used to identify the target through feature matching technology,so as to correct the initial position and direction of UAV.Then,according to the global threshold method and the characteristics of battery board,the image segmentation is carried out and the inspection path is extracted.Finally,in the process of UAV inspection,the Turn and stop strategies.The experimental results show that the inspection system meets the requirements of high precision and high efficiency photovoltaic inspection.
