Abstract: A distance measuring device includes: a first imager and a second imager provided so as to be aligned such that fields of view thereof overlap each other; a projector configured to project pattern light in which a plurality of types of light regions having wavelength bands different from each other are distributed in a predetermined pattern, onto a range where the fields of view overlap; and a measurer configured to measure a distance to an object surface onto which the pattern light is projected, by performing a stereo correspondence point searching process on images respectively acquired by the first imager and the second imager.
