Abstract: According to the requirements of the short-distance inspection of the transmission line, a quadrotor UAV is used to solve the problems of inefficiency, unsafe and technical threshold of routine inspection means. The images of the line defects and potential problems are located and collected with the aerial views of the cameras. Combined with the GPS of the transmission tower, an autonomous flight inspection is presented according to the default track points. A manual flight inspection is used to acquire the comprehensive images of the line's key components by observing the real-time images of towers transmitted by airborne equipments. The inspection system enhances the ability of the line state management and emergency solution. Also it can provide a full range of the line information support for the safety assessment, pre-disaster investigation, pre-warning of the accident, disaster repair, and even the state of maintenance and life cycle management.
