Abstract:

We developed the Mirror Tele-camera System for efficiency improvement of inspection by TV-camera. And we developed the Sewer Internal-Image Conversion System and the Sewer-Inspection Support System by using the image of the Mirror Tele-camera System. 1) The Mirror Tele-camera System, a camera that can obtain a 360-degree side scan image to improve pipeline inspection and records the internal surfaces of a sewer as images on digital video tape. 2) The Sewer Internal-Image Conversion System, which makes a projection image of a pipeline scanned by the Mirror Tele-camera. 3) The Sewer-Inspection Support System, which is a semi-automated system of diagnosing the damaged points in the pipeline from the projection image. It is likely to be able to contribute to efficiency improvement of sewer-works by effectively using those 3 systems.
