1. A method for implementing augmented reality, comprising: acquiring real image information by using a camera; acquiring one or more target objects selected by a user from the real image information; with respect to each target object, acquiring an identification image that is used to identify the target object, and categorization information of the target object separately; acquiring an image template corresponding to the categorization information, and performing image matching of the image template with the identification image to identify each target object; and acquiring augmented information corresponding to each identified target object separately by using a correspondence between the augmented information and the image template matched to the identification image which identifies the target object, and simultaneously displaying the identification image of the target object and the augmented information to form the augmented reality.
