- W2903858801 abstract "For the problem of low availability and high environmental dependence of the traditional floor positioning technology, this paper proposes an indoor floor positioning method based on the smartphone’s barometer. First, one can get an initial floor location through the entering detection algorithm. Second, the user’s going upstairs or going downstairs activities are identified through the characteristics of air pressure and the altitude. Then we can get the latest floor position.In order to solve the problem of the floor misjudgment from different mobile phone’s barometer having different performance, this paper puts forward a pressure sensor relative error calibration method based on the neighbors. It can be used to calibrate the pressure data from the different cell phones, and effectively reduce the errors of the air pressure estimation elevation that is caused by the heterogeneity of the mobile phones. Finally, the experiment results show that the rate accuracy of the floor identification can reach more than 85% while reducing environmental dependence and improving availability." @default.
