Estimating the term…
A system and method, which utilizes incremental smoothing and mapping (iSAM) algorithm and automatically builds a beacon location map using various sensor and environmental information. The aforesaid iSAM algorithm fuses received signal strength indicator (RSSI) values available from different beacons in the environment and the information provided by the IMU sensor. The aforesaid iSAM algorithm is capable of simultaneously generating beacon and landmark map and localize the mobile computing device in the environment without having any prior information about any beacon locations. To accommodate for noisy sensor data and achieve better convergence for the iSAM algorithm, the system uses a prior beacon location map, which contains location information of some of the BLE beacons located in the environment. These known beacon locations provide cleaner environmental information to the iSAM algorithm and hence improve the overall estimation of beacon locations, which were not available apriori.
A computer-implemented method, the method being performed in a computerized system comprising a central processing unit, a localization signal receiver, a plurality of sensors, separate and distinct from the localization signal receiver, and a memory, the computer-implemented method comprising:
A non-transitory computer-readable medium embodying a set of computer-executable instructions, which, when executed in connection with a system comprising a central processing unit, a Bluetooth localization signal receiver, a plurality of sensors, separate and distinct from the Bluetooth localization signal receiver, and a memory, cause the system to perform a method comprising:
A computerized system comprising a central processing unit, a Bluetooth localization signal receiver, a plurality of sensors, separate and distinct from the Bluetooth localization signal receiver, and a memory, the memory storing a set of computer-readable instructions causing the system to perform a method comprising:
