Abstract

The invention relates to a wire ice-shedding skip trajectory binocular measurement method, which comprises the steps of (1) system calibration: erecting a binocular measurement device at a location parallel to a to-be-measured lead, connecting the measurement device with a host computer to form a measurement system in the two-camera-based measurement manner, and acquiring the internal parameters and the structural parameters of the measurement system through the computation of the host computer; (2) picture shooting: continuously shooting a ice-shedding lead by means of the measurement device in the look-up gesture; (3) data processing: conducting the data processing operation by means of the host computer, completing the stereo matching process of the two cameras with lead picture matching points and calculating the three-dimensional coordinates of the matching points; (4) trajectory displaying: conducting the coordinate transformation for the calculation result of the data processing operation, and displaying the lateral motion trajectory, the longitudinal motion trajectory and the axis motion trajectory of the ice-shedding lead. According to the technical scheme of the invention, the method integrates the binocular vision technology, the digital image processing technology, the computer software technology and the like, thus being advanced in technology.

Description

technical field [0001] The invention belongs to the field of power transmission line measurement equipment, in particular to a binocular measurement method for conductor deicing and jumping tracks. Background technique [0002] Among the natural disasters faced by the power transmission system, the phenomenon of conductor de-icing and jumping is the most common, which seriously threatens the safety of the power transmission system. In recent years, a large number of researches have been carried out at home and abroad on the problem of wire deicing, mostly using numerical simulation methods to analyze the dynamic tension, wire jumping height, vertical load, internal force of tower members and spacers, and foundation bending during the deicing process. Moments etc. were calculated. A small number of scholars have carried out simulation experiments on wire de-icing, and have actually measured relevant data items. Compared with the measurement of tension, insulator string axia...
