Three-dimensional information restoration apparatus, three-dimensional information restoration system, and three-dimensional information restoration method

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional information restoration apparatus capable of improving the accuracy of restoring three-dimensional coordinates which are restored from two captured images.SOLUTION: The three-dimensional information restoration apparatus includes: an area specification unit that specifies a first area in a first image captured by a first imaging apparatus and a second area corresponding to the first area in a second image captured by a second imaging apparatus; a corresponding point detection unit that detects plural corresponding points at which first feature points contained in the first area correspond to second feature points contained in the second area; and a three-dimensional coordinate derivation unit that restores three-dimensional coordinates as inverse projections of the first feature points based on plural corresponding points.SELECTED DRAWING: Figure 2
