Document Type and Number:
WIPO Patent Application WO/2021/049281
Kind Code:
A1
Abstract:
An image processing device 130, wherein an image acquisition unit 170 acquires a captured image from a stereo camera 110 of a head-mounted display. An image correction unit 172 consults a displacement vector map representing a displace vector of pixels required for correction, and performs correction on respective partial images smaller than a single frame. A feature point extraction unit 176 extracts feature points from the partial images, and sequentially supplies same to a feature point cross-check unit 178. The feature point cross-check unit 178 establishes the correspondence of feature points of a plurality of images. A spatial information acquisition unit 180 acquires information on a real space on the basis of correspondence information of the feature points.
