An object recognition system including an image data storage unit to store a captured image, a feature extraction unit to extract an image having a predetermined rotational component among rotational components of the image stored in the image data storage unit and to extract feature vectors based on the extracted image, a database unit to store object information, a recognition unit to determine whether an object corresponding to the captured image is present in the database unit through comparison between the feature vectors extracted by the feature extraction unit and the object information stored in the database unit and to recognize information on the object stored in the database unit based on determination as to whether the object corresponding to the captured image is present in the database unit, and a system administration unit to receive the information on the object recognized by the recognition unit.
