Longitudinal Defects Detection

Longitudinal Defects Detection

This specific inspection, together with the Transversal Defect Detection, is responsible for detecting Over Head Line components and their possible failures.

A set of elements and parameters need to be extracted to ensure safety of the Catenary.

Longitudinal Defects Detection System

Longitudinal Defects Detection System inspects infrastructure devices that reside in the vertical plane along the track longitudinal axis such as catenary rope and contact wire, droppers, fixed points, and insulators. It recognizes changes on the infrastructure devices. The analysis can also be performed taking into account data coming from a catenary geometry measurement system for cross-correlation of measured data. High performance, smart vision algorithms extract relevant parameters and produce defect reports.
