METHOD AND APPARATUS FOR TRACKING OBJECTS WITH LOCATION AND MOTION CORRELATION

摘要

In a tracking of a position and motion of a device, a set of hypothetical locations of the device is generated. Hypothetical locations among the set are propagated to respective hypothetical next locations, using respective location-specific propagation models associated with the hypothetical locations. Sensor information having correlation to a location of the device is received. An importance weighting for the hypothetical next locations is calculated using the new sensor information. Probable locations of the device are generated using the importance weighting.

1. A method for tracking position and motion of a device, comprising:
generating a set of hypothetical locations of the device; propagating each of at least a sub-set of the hypothetical locations to a respective hypothetical next location, based on respective location-specific propagation models associated with the hypothetical locations; receiving sensor information having correlation to a location of the device; calculating an importance weighting, based in part on the new sensor information, for at least a plurality of the hypothetical next locations, and generating a corresponding plurality of hypothetical next location importance weightings; and generating probable locations of the device based at least in part on the importance weighting.
