1. An augmented reality (AR) share system, comprising:
a device for sharing AR information, the device configured to select a predetermined number of specific frames, among a plurality of frames used for a registration process of a cloud anchor; and
a server configured to:
receive the predetermined number of specific frames selected by the device; and
generate an auxiliary plane anchor defining a position of a virtual object based on the predetermined number of specific frames selected by the device, wherein the device comprises:
an AR system configured to register a position of the cloud anchor for coordinate synchronization of the virtual object; and
an image selector configured to:
extract frames exceeding a number of set reference feature points, among the plurality of frames used to register the cloud anchor, based on feature point information set in the AR system; and
select the predetermined number of specific frames with a minimum ratio of feature points overlapping between the frames, among the plurality of frames, which is higher than a predetermined reference ratio, and
wherein the number of the set reference feature points and the minimum ratio of feature points comprise references for selecting images used for the AR share system to generate virtual objects.
