A distance measuring apparatus includes: a reference object; a plurality of optical systems; imaging sections for converting images of an object for distance measurement and the reference object formed in the respective imaging regions into picture data; and a calculation section. The calculation section generates a plurality of picture data of the reference object by light of a first wavelength band and a plurality of picture data of the object for distance measurement by light of a second wavelength band, the second wavelength band being longer in wavelength than is the first wavelength band. From the plurality of picture data, parallax amounts of the reference object and the object for distance measurement are calculated. A distance to the object for distance measurement is calculated based on a corrected parallax amount of the object for distance measurement.
