Abstract: According to the disclosed embodiments, virtualized information of a three-dimensional position for a position selected by the user is provided so that the user can place virtual content at an accurate position when authoring AR content. According to an embodiment, an apparatus for generating point cloud data includes a hardware processor to implement a feature point extractor to extract feature points from images obtained by capturing a three-dimensional region, a point cloud data generator to generate point cloud data related to the three-dimensional region on the basis of the extracted feature points, an overlay image display to display the generated point cloud data by overlaying the point cloud data on a currently captured image, and a three-dimensional position determiner to determine a three-dimensional position for a position selected by a user in the image.

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.
