Abstract
Official abstract text for this publication.
Provided are a human-tracking method and a robot apparatus. The human-tracking method includes receiving an image frame including a color image and a depth image, determining whether user tracking was successful in a previous image frame, and determining a location of a user and a goal position to which a robot apparatus is to move based on the color image and the depth image in the image frame, when user tracking was successful in the previous frame. Accordingly, a current location of the user can be predicted from the depth image, user tracking can be quickly performed, and the user can be re-detected and tracked using user information acquired in user tracking when detection of the user fails due to obstacles or the like.
First claim
Opening claim text (preview).
What is claimed is: 1. A human-tracking method performed by a robot apparatus, comprising: receiving an image frame including a color image and a depth image; determining whether user tracking was successful in a previous image frame; determining a location of a user and a goal position to which a robot apparatus is to move based on the color image and the depth image in the image frame, when user tracking was successful in the previous frame, controlling a movement of the…
