OVERHEAD CABLE IDENTIFICATION METHOD AND OVERHEAD CABLE IDENTIFICATION SYSTEM

WIPO Patent Application WO/2022/176160

A1

The purpose of the present invention is to provide an overhead cable identification method and an overhead cable identification system capable of quickly and safely checking the presence or absence of an overhead cable support wire without using a high-place work vehicle.　The overhead cable measurement system according to the present invention comprises a measuring device 10 and an analysis device 20 and is characterized in that: the measuring device 10 obtains the point group data D of an overhead cable 30; and the analysis device 20 detects, from the point group data D, a plurality of point groups included in a space having a surface vertical to a cable route and an arbitrary width in the cable route, calculates the statistical value of the point groups included in the space, and determines the presence or absence of the overhead cable support wire by the magnitude of the statistical value with respect to a predetermined threshold value.
