摘要： A method for providing an AR object based on an identification code by a tracking application executed by at least one processor of a terminal according to the present disclosure comprises generating an AR library, which is a data set providing a predetermined augmented reality environment, based on at least one or more target objects; storing the AR library by matching the AR library to a first target object and a second target object; and providing an augmented reality environment based on the second target object and the AR library matched to the first target object when being connected to the web environment based on the first target object, wherein providing an augmented reality environment comprises obtaining a first image capturing the first target object through an image sensor of the terminal, detecting the first target object based on the obtained first image, obtaining an augmented reality web environment access link for providing the AR library matched to the detected first target object, obtaining a second image capturing the second target object through an image sensor of the terminal in the augmented reality environment accessed through the obtained link, detecting a second target object based on the obtained second image, and controlling a first virtual object included in the AR library to be augmented and displayed on the detected second target object.
