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