TRACKING METHOD OF MULTIPLE OBJECTS USING MOBILE DEVICE IN AUGUMENTED REALITY ENVIRONMENT AND SYSTEM USING THE SAME

摘要

PURPOSE: A method for tracking a plurality of objects under augmented reality environments using a mobile device and a system thereof are provided to enable the mobile device to track a plurality of objects with a small delay even though a limited network bandwidth is formed between a server and the mobile device. CONSTITUTION: A server-sided camera photographs one or more objects(S910). An object tracking unit tracks the photographed objects by a modified natural feature tracking method(S920). A positional relation calculating unit calculates a positional relation of the tracked objects(S930). A mobile device detects and tracks one object(S940). The mobile device tracks other objects as well as the tracked object based on the positional relation(S950).
