Apparatus and method for providing augmented reality using object list

An apparatus to provide augmented reality (AR), comprising:

• an image acquisition unit to acquire an image comprising a first object;
• a supplementary information acquisition unit to acquire supplementary information comprising location information of a terminal that captures the image of the object;
• an object recognition unit to recognize the first object from the acquired image, and to recognize a second object from the acquired image if the object recognition unit fails to recognize the first object;
• and
• a candidate nomination unit to nominate at least one or more candidate objects for the first object based on information on at least one of the recognized second object and the acquired supplementary information.

A terminal to display augmented reality (AR), comprising:

• a camera;
• an image acquisition unit to acquire an image comprising a target object through the camera;
• a first transmission unit to transmit the acquired image comprising the target object or feature point information of the target object to a server;
• a second transmission unit to transmit supplementary information comprising location information of the terminal;
• a reception unit to receive candidate objects extracted based on the supplementary information from the server;
• and
• a display unit to display the received candidate objects to select the target object from the displayed candidate objects.
