Automatic High-Speed Optoelectronic System for Dimensional Inspection of Distant Articles in Industry and Transport

Abstract:

Advanced automated optoelectronic system for contact wire wear inspection on the go using a structured light method is presented. The algorithm of the video stream analysis and approaches to its implementation using high-performance electronic equipment are given. The automated system described has allowed measuring wear parameters with 10 mm interval at the inspection wagon velocity of 60 km per hour. The root-mean-square error for the measurements of the remaining height and contact plot constitutes 0.15 and 1.5 mm2 correspondently that allows one to make a considered decision about changing a worn section of a contact wire network. The system also can be utilized to inspect public transportation network and to measure the geometric parameters of cables and tubes being fabricated with rolling technique.
