Abstract
An augmented reality content display method and an apparatus and system for performing the same are disclosed. The method includes extracting, by a feature point classification device, feature points from a plurality of images captured while changing a capture point such that at least one of a capture position and a capture orientation is changed, tracking, by the feature point classification device, feature points extracted from the same area of the plurality of images to associate the tracked feature points with one another, calculating, by the feature point classification device, uncertainty about a position of the associated feature points, and classifying and storing, by the feature point classification device, the associated features as a recognition reference feature point group or a dummy feature point group according to the position uncertainty.
