Abstract
The subject matter disclosed herein relates to adjusting an elevation component of a estimated location based, at least in part, on sensor-based dead reckoning.
Claims36
A method, comprising:
- determining an estimated initial position for a mobile station, wherein the estimated initial position comprises an elevation component;
- detecting an interior feature of a building at least in part by detecting a change in position of the mobile station with respect to said estimated initial position in response to sensor data by detecting a change in the elevation component;
- and
- adjusting the detected change in the elevation component using information related to the detected interior feature.
1 more element
A mobile station, comprising:
- a processor to determine an estimated initial position for the mobile station, wherein the estimated initial position comprises an elevation component;
- an inertial measurement unit to detect an interior feature of a building at least in part by detecting a change in position of the mobile station with respect to said estimated initial position in response sensor data by detecting a change in the elevation component;
- the processor being further adapted to adjust the detected change in the elevation component using information related to the detected interior structure.
An article, comprising:
- a storage medium having stored thereon instructions that, if executed, enable a computing platform to:
- determine an estimated initial position for a mobile station, wherein the estimated initial position comprises an elevation component;
- detect an interior feature of a building at least in part by detecting a change in position of the mobile station with respect to said estimated initial position in response to sensor data by detecting a change in the elevation component;
- and
- adjust the detected change in the elevation component using information related to the detected interior feature.
