Abstract:
1. A method for estimating a location of an object within a mobile reference frame comprising: receiving sensor data from an accelerometer associated with said object; determining from said sensor data that said mobile reference frame is executing one of a set of pre-determined maneuvers; in response to said determining one of a set of predetermined maneuvers, applying said sensor data to a mathematical model associated with said executed maneuver, said model being trained with previously obtained data from one or more reference accelerometers positioned at known locations within said mobile reference frame; estimating said location of said object by applying said sensor data to said mathematical model; receiving sensor data from at least one reference accelerometer positioned at a known location within said mobile vehicle reference frame; comparing the sensor data received from the accelerometer associated with the object to the sensor data received from the at least one reference accelerometer; and refining the location estimate for the object based on the comparison.
