摘要： In a method for learning a target object, performed by a computer-aided design program of an authoring computing device, one embodiment of the present disclosure provides a method for learning a target object by extracting edges from a digital model of a target object, where the method comprises displaying the digital model of a target object which is an image recognition target, extracting a first edge with visibility greater than or equal to a threshold from a first area of the digital model of the target object, detecting a second edge with visibility greater than or equal to a threshold from a second area different from the first area of the digital model of the target object, and generating object recognition library data for recognizing a real object corresponding to the digital model of the target object based on the first and second edges.

摘要： The present disclosure provides a method for recognizing 2D code information. A method for recognizing 2D code information according to the present disclosure, which is related to a method for recognizing 2D code information by capturing a 2D code image composed of rectangular cells, comprises obtaining a 2D code image using a mobile device equipped with a camera or an image capture device; performing a first data extraction process that identifies individual blocks storing a position pattern, an alignment pattern, and data from the obtained 2D code image; setting a first weight for removing outer blocks located outside a line connecting the position pattern and the alignment pattern with respect to a central block among the individual blocks of the 2D code image on which the first data extraction process has been performed; partitioning inner blocks located inside the position pattern and the alignment pattern among individual blocks of the 2D code image into a plurality of block groups composed of at least one or more inner blocks and setting a second weight for determining whether to select a block group according to a recognition rate of blocks constituting each block group; removing outer blocks set to the first weight and selecting a block group for which a weight has been set as having a high recognition rate among block groups set to the second weight; determining and recognizing a 2D code by comparing the selected block group with a block group of a pre-stored 2D code; and displaying an object to a user in the form of augmented reality based on the recognized 2D code information.
