Catenary Eye Applied with Image Analysis Processing Technologies

摘要

The Catenary Eye is a catenary (trolley line) inspection unit to which image analysis processing technologies are applied. It assures high accuracy inspections in non-contact mode. It can be installed on a conventional general measuring vehicle, a motorcar, a railroad motorcar, or even on a schedule-operating car of Shinkansen,etc. Therefore, the measurements of the actual running can be realized at the scheduled running speed. The items to be measured are the trolley height, displacement, hard point, abrasion, shape, current collecting condition, and others. According to the items to be measured, a camera may be combined for measurements. One of the features of an image-borne inspection is that the result of the measurements and the real images (abrasion, displacement, current collection, etc.) taken at that time can be confirmed simultaneously at the playback screen. A rough examination can be carried out before rushing to the accident spot.
