Patent attributes
A mobile computing device includes: a tracking sensor; a proximity sensor; and a controller coupled to the tracking sensor and the proximity sensor, the controller configured to: obtain a sequence of sensor datasets, each sensor dataset including: (i) a location of the mobile computing device, in a local coordinate system, generated using the tracking sensor, (ii) a proximity indicator generated using the proximity sensor, defining a range to a fixed reference device, and (iii) a predefined location of the reference device in a facility coordinate system; determine, from the sequence, an adjusted pose of an origin of the local coordinate system in the facility coordinate system; and generate, using a current location of the mobile device in the local coordinate system and the adjusted pose, a corrected location of the mobile computing device in the facility coordinate system; and execute a control action based on the corrected location.
