LOCALIZATION OF A MOBILE ROBOT DEVICE, METHOD AND MOBILE ROBOT

摘要

The present invention may include a camera unit receiving an image signal; a feature point extraction unit determining and selecting feature points of the image signal; a storage unit in which a position of an actual landmark and an image template information which can be obtained on a path in which a robot would be moving are stored; a feature point selection unit improving accuracy of the feature point candidates; a feature point matching unit comparing information in the feature point selection unit with information in the storage unit to match the corresponding feature points; and a position determination unit finding a vector from a central coordinate of the landmark determined by matched optimal feature points to the camera, and determining a present position of a mobile robot.
