Aiming at the problem that the traditional floor positioning method has high environmental reliance and low availability

an indoor floor positioning method based on behavioral perception of smartphone is presented. This method uses the"entering"detection algorithm to sense the specific behavior of pedestrians entering the building.It recognizes up and downstairs activities of pedestrians based on air pressure up and downstairs behavior detection algorithm. Indoor air pressure floor estimation model based on the air pressure-altitude relationship is established.The experimental results show that the floor localization method achieves a floor recognition accuracy of over 85 %under the conditional of relying only on the barometer of smartphone and a very small amount of AP signal sources

which greatly reduces the dependence of the positioning method on the signal environment and achieves high-precision and high-available floor positioning.
