Measurement System for Prefabricated Jumper Length of Transmission Line Towers
The accuracy of measuring the jumper length of transmission line towers has been a critical factor affecting the stable operation of power systems.Traditional measurement methods often suffer from insufficient precision,complexity,and susceptibility to human error.To enhance the accuracy and efficiency of jumper length measurement,a 3D modeling technique based on visible light imagery is proposed.This method leverages feature extraction,structure from motion,and dense reconstruction techniques to achieve precise 3D modeling of the jumper,and simulates the jumper length using the catenary model,providing an accurate pre-installation simulation.Experimental results demonstrate that this method performs in capturing the spatial position and dimensions of both the tower and the jumper,significantly improving measurement accuracy and efficiency.Compared to existing techniques,this approach achieves a favorable balance between accuracy and efficiency,meeting the practical demands of engineering applications effectively.
