3D optimization model of overhead transmission wire based on UAV aerial survey modeling

The 3 d optimization model of traditional overhead transmission conductor is difficult in data acquisition and update, limited model accuracy, computational complexity and high resource consumption, insufficient consideration of external factors and lack of real-time monitoring and feedback, based on this, the 3 d optimization model of overhead transmission conductor based on UAV aerial survey modeling is proposed. Based on the aerial triangulation method, control the work of the information acquisition device, collect the position information of the device, use the Canny operator edge detection algorithm to detect the edge information in the image; use tilt photography 3 D reconstruction technology to provide the 3 D scene model of overhead transmission wire. The experimental results show that the error rate of the proposed method is 0.93%, and the error rate is small. The predicted values of the iterations of 120 and 140 times are 0.7dB and 0.3dB larger, respectively, which is consistent with the measured results and provides better support for the optimization, operation and maintenance of the transmission system.
