Abstract
A distance measuring apparatus includes a reference object distance calculation section which calculates a distance to a reference object based on a two-dimensional image in which the reference object, which includes a plurality of feature points having obvious three-dimensional coordinate correlations, is captured, and a correction amount calculation section which calculates a correction amount for correcting a distance image by comparing the calculated distance to the reference object with a distance measurement value to the reference object in the distance image.
