Abstract

A three-dimensional measurement system capable of realizing high-speed processing while increasing measurement resolution are provided. The system includes: an image capture unit including a first and second image capture units that are spaced apart; a first calculation unit calculates a parallax at first feature points in the images using distance information of a three-dimensional measurement method other than a stereo camera method or information for calculating a distance, using at least one of the first and second image capture units; and a second calculation unit calculates a parallax at second feature points based on a corresponding point for the second feature point by using the stereo camera method using the first and second image capture units, and specifies a three-dimensional shape based on the parallax at the first and second feature points. The second calculation unit sets a search area based on the parallax at the first feature points.
