抄録

In order to maintain the safety of steel tubes which have been used externally as structural members in buildings and large scale structures for a long period, the inner walls of the tubes are often investigated by inspectors. In the present study, to reduce this visual inspection, they have paid attention to the color of the rust which appears in the corroded wall, and have tried to detect corroded regions by using color image processing. Namely, the input RGB color images are transformed to color sensitive space Lab, and three parameters, lightness, chroma, and hue angle are calculated and investigated around the corroded region. Moreover, they have developed this method to be able to inspect the video tape observing corroded regions in real time by using a commercial high speed image processing board.
