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 21):
A computer-implemented method for tracking vehicles that are perceived by an autonomous vehicle, the method comprising:\n obtaining, by one or more computing devices included in the autonomous vehicle, state data descriptive of a previous state of a tracked vehicle that is perceived by the autonomous vehicle, wherein the previous state of the tracked vehicle comprises at least one previous location of the tracked vehicle or a vehicle bounding shape associated with the tracked vehicle; predicting, by the one or more computing devices, one or more first locations for a first portion of the vehicle bounding shape based at least in part on the state data; obtaining, by the one or more computing devices, observation data descriptive of one or more sensor observations; determining, by the one or more computing devices, a second location of a second portion of an observation bounding shape associated with the tracked vehicle based at least in part on the observation data; and determining, by the one or more computing devices, at least one estimated current location of the first portion of the vehicle bounding shape associated with the tracked vehicle based at least in part on a comparison of the one or more first locations for the first portion of the vehicle bounding shape to the second location of the second portion of the observation bounding shape.
