摘要

PROBLEM TO BE SOLVED: To perform leakage oil detection with high detection precision capable of detecting even colorless oil without making devices complex.;SOLUTION: A leakage oil detection device according to the present invention comprises, for solving the problem to be solved: an ultraviolet light source which irradiates a body to be measured with ultraviolet light; a color imaging unit which photographs fluorescent light from the body to be measured being irradiated with the ultraviolet light; a processing part which determines oil leakage from the image of the body to be measured photographed by the color imaging unit; and a display part which displays a result of the determination by the processing part. The processing part specifies an oil leakage region based upon correlation between color saturation and luminosity of the color image of the body to be measured photographed by the color imaging unit and color saturation and luminosity of a region where leakage oil does not stick on a surface of the body to be measured, and outputs the specified oil leakage region to the display part.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
