Abstract

An optical structured light method and an opto-electronic system for automatic noncontact distant measurements of wear and defects detection for a contact wire electro-supply network are presented. The system industrial prototype can extract the main technological wire parameters, first of all, the remaining height with RMS error down to 0.15 mm and the wire cross-section area with RMS error of 1.5 mm². This information is sufficient for confident decision on operation of contact wire electro-supply network. This method could be applied for automatic wire wear measurement and defects detection for trams, trolleybuses and other electro-supply vehicles.
