Abstract

The invention relates to the technical field of power line inspection, and discloses a monocular SLAM system for high-voltage power transmission line inspection. The system is characterized in that anoverhead power transmission line inspection robot uses a visible light and infrared double-light fusion nacelle, so that a visible light image and an infrared image of the same scene can be obtainedat the same time, wherein pixel points of the visible light image and the infrared image are in one-to-one correspondence; an inspector or an automatic fault identification algorithm checks whether faults such as rusting, cracking, falling and the like exist on the surface of hardware, whether foreign matters exist on a high-voltage power transmission line and whether bird nests and the like existon a tower to influence the power transmission safety according to the images; whether the temperature of the power transmission line is abnormal is judged through the infrared image so as to determine whether the power transmission line is abnormal; three-dimensional reconstruction is performed on a power transmission line channel through a visual SLAM technology; and whether the power transmission safety is affected can be known through a three-dimensional map.

Description

technical field [0001] The invention relates to the technical field of transmission line inspection, in particular to a monocular SLAM system for high-voltage transmission line inspection. Background technique [0002] Since the high-voltage transmission lines are widely distributed and run under the open air for a long time, they are often affected by the natural environment and human activities, which will cause hidden dangers to the normal operation of the transmission lines. Therefore, it is necessary to observe and inspect the components of the transmission lines and measurement to grasp the operating status of the line, timely discover equipment defects and problems that threaten line safety. At the same time, due to the distribution of high-voltage transmission lines in various terrain conditions, and the variety and complexity of equipment, manual inspection work is intensive and dangerous. [0003] In order to solve the problems faced by manual inspections, the pow...
