Test: Estimate the initial position through WIFI fingerprint positioning, lights, geomagnetism, etc., and then merge the results of PDR, geomagnetism, and wifi positioning to get the final position. The floor can be judged roughly based on the barometer. When there is a weak change in air pressure between floors, the floor information can be detected by fusing other signals (wifi, geomagnetism, lights, etc.). [references]
