Abstract:
The present disclosure provides systems and methods for tracking vehicles or other objects that are perceived by an autonomous vehicle. A vehicle filter can employ a motion model that models the location of the tracked vehicle using a vehicle bounding shape and an observation model that generates an observation bounding shape from sensor observations. A dominant vertex or side from each respective bounding shape can be identified and used to update or otherwise correct one or more predicted shape locations associated with the vehicle bounding shape based on a shape location associated with the observation bounding shape.

Claim (Index 38):
An autonomous vehicle, comprising:\n a tracking system configured to track vehicles perceived by the autonomous vehicle, wherein the tracking system comprises: a motion model configured to predict one or more first shape locations for a vehicle bounding shape associated with a tracked vehicle; and an observation model configured to provide a second shape location of an observation bounding shape associated with the tracked vehicle based at least in part on observation data derived from one or more sensors; one or more processors; and one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, cause the one or more processors to perform operations, the operations comprising:\n identifying a first dominant portion for each of the one or more first shape locations predicted for the vehicle bounding shape; \n identifying a second dominant portion for the observation bounding shape; \n performing, for each of the one or more first shape locations, a comparison of the first dominant portion to the second dominant portion; and \n determining at least one estimated current location of the first dominant portion for the vehicle bounding shape based at least in part on the comparison.
