Abstract
The invention discloses an indoor positioning method and apparatus. The method includes: acquiring current cell signal strength information of a terminal located indoors; determining, according to 3D indoor positioning matching information, horizontal position information and height information of an indoor grid that are corresponding to the current cell signal strength information, where the 3D indoor positioning matching information includes a correspondence between cell signal strength information of the indoor grid and the horizontal position information and the height information of the indoor grid; and determining, according to the horizontal position information and the height information of the indoor grid, a horizontal position at which the terminal is located indoors and a height at which the terminal is located. In this way, high-accuracy 3D indoor positioning can be implemented.
