Abstract
This disclosure provides methods and systems of classifying a vehicle using motion vectors associated with captured images including a vehicle. According to an exemplary method, a cluster of motion vectors representative of a vehicle within a target region is analyzed to determine geometric attributes of the cluster and/or measure a length of a detected vehicle, which provides a basis for classifying the detected vehicle.
Claims28
A computer-implemented method of classifying a vehicle captured with an image capturing device, the image capturing device oriented to include a field of view spanning a vehicle detection target region, the method comprising:
- a) generating a cluster of motion vectors representative of a vehicle detected within the target region, the cluster of motion vectors including motion vectors representative of the vehicle's body detected within the target region;
- b) associating one or more attributes with the cluster of motion vectors;
- and
- c) classifying the vehicle detected according to the one or more attributes associated with the cluster of motion vectors.
An image capturing system for classifying a vehicle captured by the image capturing system, the image capturing system comprising:
- an image capturing device oriented to include a field of view spanning a vehicle detection target region;
- and
- an image processor operatively associated with the image capturing device, the image processor configured to perform a method of classifying a vehicle captured with the image capturing device comprising:
- a) generating a cluster of motion vectors representative of a vehicle detected within the target region, the cluster of motion vectors including motion vectors representative of the vehicle's body detected within the target region;
- b) associating one or more attributes with the cluster of motion vectors;
- and
- c) classifying the vehicle detected according to the one or more attributes associated with the cluster of motion vectors.
