Abstract
Provided is an oil leakage detection apparatus by which oil leakage detection is performed even for colorless oil with high detection accuracy and without complicating the apparatus. The oil leakage detection apparatus of the invention includes a distance measurement unit configured to measure a distance to the oil-input machine, an ultraviolet light source configured to irradiate the oil-input machine with ultraviolet light, a color imaging unit configured to capture an image of the oil-input machine irradiated with ultraviolet light, an image processing unit configured to diagnose oil leakage of the oil-input machine based on the distance measured by the distance measurement unit and the captured image of the color imaging unit, and a display unit configured to display a processed image processed by the image processing unit. Further, an oil leakage detection method of the invention includes measuring a distance from an oil-input machine, irradiating the oil-input device with ultraviolet light, capturing an image of the oil-input machine irradiated with ultraviolet light, diagnosing oil leakage of the oil-input machine based on the measured distance and the captured image, and di…
