Abstract: The present invention relates to a method and a system for three-dimensional automatic scan based primitive, and estimates a three-dimensional model of an object from three-dimensional scan data of the object, recognizes a shape of the three-dimensional model by using fitting with at least one primitive, evaluates confidence of each of surface points of the three-dimensional model based on similarity between the at least one primitive used for shape recognition and the shape of the three-dimensional model, and scans the object in a series of views determined based on the confidence of each of the surface points, and thus, accuracy of the three-dimensional scan of the object is improved and time required for scan may be reduced.

Abstract: A method and an apparatus for tracking an entity based on feature data independent of an augmented reality engine are provided. A URI for feature data of an entity is generated from a combination of a name of the entity and a name of an AR engine, feature data of the entity representing characteristics of the entity is acquired in a format capable of being processed by the AR engine by using the URI, the entity is tracked in an augmented reality space by executing the AR engine based on the acquired feature data, and thus, an entity based on feature data independent of an augmented reality engine may be tracked.
