1. A computer-implemented method of tracking a target object in an object recognition system, the method comprising:
acquiring a plurality of images with a camera;
acquiring offline map data of the target object; and
simultaneously tracking the target object and dynamically building online map data from the plurality of images, wherein tracking the target object includes selecting between the online map data and the offline map data for tracking the target object based at least in part on a size of the target object relative to an image in which the target object is being tracked.
