Embodiments of the invention provide a positioning method and device. The method comprises the following steps of: obtaining fuzzy positioning information of a target interest point; determining a plurality of pieces of reference positioning information associated with the target interest point; determining a confidence coefficient score of each piece of reference positioning information; and calibrating the fuzzy positioning information on the basis of the confidence coefficient scores so as to obtain accurate positioning information of the target interest point. Through the positioning method and device, accurate positioning of target interest points is realized; positioning information of multiple reference resources is used for positioning, so that the positioning correctness is ensured; and acquisition does not need to be carried out on the spot, so that the positioning timeliness is ensured.
