Abstract

Inspection system of railway facilities under development since 1991 using continuous scan image (CSI) to be taken by a linear sensor camera, has reached a practical application stage. Many railway facilities are so extensive that this system will provide an effective tool of taking those images. We report especially on the tunnel inspection system in this paper. The structural soundness of a railway tunnel is currently inspected and maintained via the visual monitoring of deformations such as a cracking on the wall. Actually, however, work environment is so bad and monitoring area so extensive that it is very difficult to follow all deformations developing on the wall to the last crack. We completed an original image processing database system and a graphical user interfac
