DEGRADATION INFORMATION ACQUISITION DEVICE, DEGRADATION INFORMATION ACQUISITION SYSTEM, DEGRADATION INFORMATION ACQUISITION METHOD AND DEGRADATION INFORMATION ACQUISITION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a degradation information acquisition device, a degradation information acquisition system, a degradation information acquisition method and a degradation information acquisition program with which it is possible to grasp the degree of degradation of oils simply.SOLUTION: The degradation information acquisition device of an embodiment comprises a wavelength determination unit, an image acquisition unit, a first degradation information acquisition unit, a determination unit and a second degradation information acquisition unit. The wavelength determination unit acquires information that indicates first to fourth wavelength regions in which appears a characteristic value of transmittance relating to oil degradation in accordance with the kind of oil. The image acquisition unit acquires image data of oils imaged in a plurality of wavelength regions of light that include first to fourth wavelength regions. The first degradation information acquisition unit acquires first degradation information on the basis of the image data of the first and second wavelength regions. The determination unit determines whether or not to acquire second degradation information on the basis of the first degradation information. The second degradation information acquisition unit acquires second degradation information on the basis of the image data of the third and fourth wavelength regions.SELECTED DRAWING: Figure 5
