Abstract
Method and apparatus for tracking three-dimensional (3D) objects are disclosed. In one embodiment, a method of tracking a 3D object includes constructing a database to store a set of two-dimensional (2D) images of the 3D object using a tracking background, where the tracking background includes at least one known pattern, receiving a tracking image, determining whether the tracking image matches at least one image in the database in accordance with feature points of the tracking image, and providing information about the tracking image in respond to the tracking image matches the at least one image in the database. The method of constructing a database also includes capturing the set of 2D images of the 3D object with the tracking background, extracting a set of feature points from each 2D image, and storing the set of feature points in the database.
