電車線路検査・状態監視への画像技術適用に関する動向調査

摘要

Recently, the practical use of a contact line inspection system which uses an image technology has increased. The advantage of the measurement by the image technology is that necessary hardware can be simplified because data can be obtained only with a camera and a light. As a result of application of the image technology, measurements with a commercial train or a road railer has extended, reducing an initial cost and an operation cost of the measurement. We investigated image technology trends by documents and actual conditions with respect to a part of advanced cases, and report the results of the investigation in this paper.%電車線路設備の検査や状態監視に画像解析技術を用いrnることは1980年代から検討事例があるが，画像解析用コrnンピュータの高性能化と相まって，近年，検測装置としrnての実用化件数が増加しつつある。
