Abstract: A method for object recognition recognizing an object included in an image comprises extracting image features from the image; extracting a first candidate object matched to each of the image features with the highest similarity score from among objects within an object database which previously stores information about a target object for recognition; extracting a second candidate object based on a first matching score of the first candidate object; and based on a second matching score of the second candidate object calculated by matching features of the second candidate object and the image features, recognizing whether the second candidate object is the target object included in the image.

Abstract: A method for providing a camera calibration includes recovering geometric information from a single rectangular image, obtaining intrinsic and extrinsic construction information of a camera based on the recovered geometric information, obtaining a shooting position and real geometric information of the camera from the obtained intrinsic and extrinsic construction information of the camera.
