It is necessary for secure commercial train services to keep the contact wires in a regular condition. Most of the contact wires are inspected by the special dedicated train set for exclusive use of measurement, such as Doctor Yellow. However it is expected to develop the inspection system using normal passenger trains and normal business operation hour, without the expensive special inspection train set. Here we developed original and compact inspection system installed on the commercial bullet train of KYUSHUSHINKANSEN. This system measured the contact points of trolley and pantograph by using image processing which acquires the sequential images of the pantograph circumference during a high-speed run with cameras installed on the narrow limits of the train roof. This report describes the image processing procedures and some measurement result of the pantograph height and contact point deviation.
