System and method for multi-layered augmented reality

摘要

A multi-layered augmented reality system and method may extract a target object and a background from an image frame, may track the target object and the background, may apply different coordinate systems to a first virtual object corresponding to the target object and a second virtual object corresponding to the background, and may independently control the first virtual object and the second virtual object.

主权项

1. A multi-layered augmented reality system, comprising:
at least one computer comprising: an extracting unit to extract a target object and a background from an image frame; a tracking unit to track the extracted target object and the extracted background; an augmenting unit to augment a first virtual object corresponding to the tracked target object and a second virtual object corresponding to the tracked background; and a display unit to display the augmented virtual object, wherein the extracting unit comprises: an object recognizer to recognize the target object in the image frame; a boundary extractor to extract a boundary of the target object; and a feature point extractor to extract a feature point from a region of the image frame corresponding to the background, which is obtained by excluding a region of the image frame which includes a region of the image frame within the extracted boundary of the target object.
