Indoor positioning method and apparatus

An indoor positioning apparatus for high-accuracy three-dimensional (3D) indoor positioning, wherein the apparatus comprises:

• a memory configured to store an instruction;
• a processor configured to execute the instruction stored in the memory;
• a transceiver configured to acquire current cell signal strength information of a terminal located indoors;
• a bus apparatus configured to connect the memory, the processor and the transceiver:
• wherein the processor is configured to execute the instruction stored in the memory to execute the following:
• determine, according to 3D indoor positioning matching information, horizontal position information and height information of an indoor grid that correspond 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
• determine, according to the horizontal position information and the height information of the indoor grid, a horizontal position and a height at which the terminal is located indoors, where the horizontal position information includes position information in a first direction and a second direction, and the first direction and the second direction are two mutually perpendicular directions in a horizontal plane.
