摘要

It is an important work to measure insulator geometric parameters for preventing pollution flashover on power transmission lines. This paper presents an effective method to measure insulator parameters based on non-touch photogrammetric method. In this paper, the insulator reconstruction takes full advantage of the rotating body’s geometry structure about the symmetry axis. The spindle of insulator can be calculated from its profile extracted from multiple insulator images acquired by calibrated cameras and radius is obtained by the homologous image points of insulator profiles. Results from real data are presented, demonstrating the efficiency of the proposed methods.
