Abstract: In response to the low measurement accuracy and acceptance efficiency of existing technologies, this study investigates the application of unmanned aerial vehicle (UAV) aerial surveying technology in the completion acceptance of power lines. The drone obtains images of power lines during flight through a high-resolution camera mounted on it. This time, image correction was performed on the images to obtain the vertical photography effect of the entire image. The real-time images captured by the drone were fused and analyzed with the data obtained from the on-site sensors to determine whether the wire laying meets the standards, thus completing the quality acceptance. The test results show that the highest and lowest altitude obtained based on unmanned aerial vehicle aerial survey are 717.85 m and 232.4 m, which are consistent with the actual results. The measurement accuracy meets the requirements for terrain data accuracy in the power line design specifications. The experimental group's aerial survey time remained stable within 1.2 hours, enabling efficient completion of aerial survey tasks and effectively improving acceptance efficiency.
