Abstract
A wear amount measuring device includes: a light emitting unit configured to emit light on an object to be measured having a wear surface; an imaging unit configured to obtain an image of the object; and a calculation unit configured to calculate a wear amount by specifying a wear surface of the object from the obtained image. A positional relationship between the light emitting unit, the imaging unit, and the object is set such that, when a dummy object to be measured having a wear surface is arranged in place of the object, the light emitting unit and the imaging unit have a specular reflection relationship relative to the wear surface of the dummy object. The calculation unit calculates the wear amount by specifying the wear surface based on a difference in brightness of the image.
