【 摘 要 】

With the development of drones, drone power inspection has become the main method of power inspection. Because of its safety, efficiency, and economic characteristics, it has been favored by the power grid. This paper discusses the application background and technical characteristics of three-dimensional modeling based on tilt photography technology in power inspection, and proposes ways to improve the accuracy of 3D modeling and the accuracy of channel defects. then, we test on a certain line in Qingyuan and have achieved good results. The modeling effect and modeling accuracy provide a high-precision and reliable operation method for the drone power patrol and can be realized.
