Abstract
An image processing device includes: a region dividing unit that divides each of a plurality of captured images captured by an in-vehicle camera into a plurality of divided regions; a feature point detection unit that detects, as a feature point, a portion exceeding a threshold value for each of the divided regions; a threshold value setting unit that sets the threshold value for each of the divided regions so as to evenly distribute the feature points detected in each of the divided regions; a feature point matching unit that performs matching by associating the feature points detected in the plurality of captured images with each other between the plurality of captured images; and a relative parameter calculation unit that calculates a relative parameter on the basis of the feature points associated between the plurality of captured images.
