摘　　要：采用无人机对高压输电线路进行巡检,存在操作现场危险性高、可视性差等缺陷。为此,采用虚拟三维环境对高压输电线路上的兴趣点(绝缘子、金具、线路)进行建模分析,可以为巡检无人机提供优化理论数据,同时还对提高巡检作业安全具有重要意义。利用Google Earth提供的API接口,在编程环境Qt平台上对某高压输电线路进行虚拟实现,并针对用于输电线路巡检多旋翼无人机机载云台系统的姿态角进行建模分析,确定采用云台对超高压输电线路兴趣点进行检视时,云台姿态角与兴趣点之间相互关系,并在软件环境中进行仿真实验。实验结果验证了所提方法的正确性和有效性。There exist such disadvantages as high site risk and poor visibility for UAVs in inspectinn of high voltage transmission lines. Modeling analysis of lhe regions of interest （ROI including insulators, fittings and lines） of the high-voltage transmissinn lines by use of a virtual three-dimensional setting can provide optimization theory data for the UAV inspection and is very, significant for improving the inspeelion safety. Virtualization of a high vnltage transmission line is achieved in a QI environment by using the API interface pnovvided by Google Earth interfaces. Modeling analysis is made of the attitude angle of the airborne multi-rotor UAV PTZ system used for transmission line inspection to determine the relationship between ROI and PTZ system and simulation is carried out in the software environment. The testing results haw, proved the correctness and effectiveness of the proposed method.
