An augmented reality method includes: capturing physical objects in a physical space, to obtain respective depth information of the physical objects; generating respective physical coordinates of the physical objects; generating a 3D map of the physical space; searching an AR deposition corresponding to the physical space; converting respective AR virtual coordinates of a plurality AR objects in the AR deposition into respective physical coordinates of the AR objects in the physical space; judging whether an AR alignment error occurs; if yes, adjusting a first AR virtual coordinate of a first AR object, among the AR objects, which causes the AR alignment error; and performing AR demonstration.
