We have developed a prototype system for leakage detection using image processing. The system detects oil, water, or vapor leaks from plant components at power plants. Its features are summarized as follows: (1) By setting the first sampled image of the scene as the reference image and storing another type of reference image as a form of an x-projection, leakage detection for oil or water, even in a steady flow, was realized; (2) Mis-detection of oil or water leaks, due to effects from vibrations of plant components and cameras could be eliminated by using non-vibrating monitoring regions; and (3) Leakage detection for oil or water required at least 200 (1X) brightness at the measured objects and a 550 X 418 (mm) vision range, while vapor leakage detection could be done in a 5000 X 3800 (mm) vision range.
