US 11,299,151 B2 · Enhanced vehicle tracking

Abstract

The present invention relates to a method and system for accurately predicting future trajectories of observed objects in dense and ever-changing city environments. More particularly, the present invention relates to substantially continuously tracking and estimating the future movements of an observed object. As an example, an observed object may be a moving vehicle, for example along a path or road. Aspects and/or embodiments seek to provide an end to end method and system for substantially continuously tracking and predicting future movements of a newly observed object, such as a vehicle, using motion prior data extracted from map data.

Claims20

Dependent claims

A computer-implemented method comprising:

determining, by a computing system, from one or more captured images of an object in an environment, a trajectory of the object in the environment;
determining, by the computing system, one or more prior trajectories of one or more prior objects in the environment;
determining, by the computing system, an amount of similarity between the trajectory of the object and the one or more prior trajectories of the one or more prior objects;
and
based on the amount of similarity, predicting at least one future pose of the object in the environment.

2 more elements

A system comprising:

at least one processor;
and
a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform:
determining from one or more captured images of an object in an environment, a trajectory of the object in the environment;
determining one or more prior trajectories of one or more prior objects in the environment;
determining an amount of similarity between the trajectory of the object and the one or more prior trajectories of the one or more prior objects;
and
based on the amount of similarity, predicting at least one future pose of the object in the environment.

5 more elements

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a computing system, cause the at least one processor of the computing system to perform:

determining from one or more captured images of an object in an environment, a trajectory of the object in the environment;
determining one or more prior trajectories of one or more prior objects in the environment;
determining an amount of similarity between the trajectory of the object and the one or more prior trajectories of the one or more prior objects;
and
based on the amount of similarity, predicting at least one future pose of the object in the environment.
