Abstract
Provided are an overhead line detection method and system based on a cable inspection robot. The cable inspection robot is suspended on the overhead line. An imaging unit and a laser emission unit are disposed at the front end of the cable inspection robot. The imaging unit is at a first angle to the overhead line. The laser emission unit is at a second angle to the overhead line. The overhead line detection method includes the following steps: controlling the laser emission unit to emit N groups of parallel laser beams to the overhead line to form N parallel laser lines on the overhead line; controlling the imaging unit to shoot the overhead line and the N parallel laser lines to acquire a target detection image; performing image recognition on the target detection image to acquire N laser line diameters corresponding to the N parallel laser lines on the overhead line; and comparing the N laser line diameters with theoretical line diameters at corresponding positions to determine whether the overhead line is abnormal. Therefore, the accuracy and efficiency of the inspection can be greatly improved, and the inspection risk can be reduced.
