Title:
DETECTION DEVICE AND METHOD FOR TRANSITION AREA IN SPACE
Document Type and Number:
WIPO Patent Application WO/2012/014403
Kind Code:
A1
Abstract:
Provided is a transition area detection device (10) capable of detecting, with high precision, a transition area in a space without using a positioning sensor. The transition area detection device (10) has a corresponding point search-use feature point selection unit (13) for selecting feature points used for determining a reference image from among feature points of an input image (captured image), a geometric transformation parameter calculation-use feature point selection unit (18) for selecting feature points used for calculating geometric transformation parameters from among feature points of the input image and feature points of the reference image, and a degree of similarity calculation-use feature point selection unit (20) for selecting feature points used for obtaining a degree of similarity between the captured image and the reference image from among the feature points of the input image and the feature points of the reference image.
