Abstract
An image processing apparatus includes an image acquisition unit that acquires a plurality of images, a corresponding point acquisition unit, a first fundamental matrix calculation unit, a depth calculation unit, a corresponding point extraction unit, and a fundamental matrix determination unit. The corresponding point acquisition unit acquires a plurality of first corresponding points of the images. The first fundamental matrix calculation unit calculates a first fundamental matrix based on the first corresponding points. The depth calculation unit calculates depths for the first corresponding points based on the first fundamental matrix. The corresponding point extraction unit extracts a plurality of second corresponding points from the first corresponding points based on the depths. The fundamental matrix determination unit calculates a second fundamental matrix based on the second corresponding points.
