Abstract
Disclosed are an object tracking system using a robot and an object tracking method using a robot. The present invention provides an object tracking system using a robot and an object tracking method using a robot capable of continuously performing object tracking without missing the corresponding object even when the object deviates from a viewing angle of a camera, in tracking an image based object (person) using a robot.
Claims17
An object tracking system using a robot, comprising:
- an image acquisition unit that acquires images in front of the robot;
- an object detector that detects an object from the images acquired by the image acquisition unit;
- a motion pattern calculator that calculates a motion pattern including a distance from the robot and a motion direction of the robot with respect to the object detected by the object detector;
- a motion pattern storage unit that stores the motion pattern calculated by the motion pattern calculator;
- and
- a current position calculator that calculates a current position of the object based on the motion pattern for the object stored in the motion pattern storage unit when the object disappears from the images currently acquired by the image acquisition unit,
- wherein tracking for the object is performed by moving the image acquisition unit based on the current position calculated by the current position calculator.
