The method includes: establishing an initial ANN; optimizing the initial ANN by using a PSO algorithm, to obtain an optimized initial ANN; training the optimized initial ANN to obtain a trained ANN. According to a positioning method and apparatus provided in the embodiments of the present invention, when an ANN is used for positioning, positioning performance is improved by using a PSO algorithm to optimize a weight and an offset of each neural element in the ANN.
