Abstract

A system for passive driver identification comprises an input interface and a processor. The input interface is configured to receive a collection of face data from a vehicle event recorder. The processor is configured to 1) determine a set of face data of the collection of face data that is associated with a trip; 2) determine a first album associated with the trip, wherein the set of face data associated with the trip is similar to face data of other trips in the first album, and wherein the set of face data associated with the trip is dissimilar to face data of a set of trips in a second album; and 3) assign an identifier that associates the trip to the first album.

Claims

1. A system for passive driver identification, comprising:

an input interface configured to;

receive face data, ignition signal data, and driver change counter data; and

a processor configured to;

identify, using a processor, a subset of the face data, a subset of the ignition signal data, and a subset of the driver change counter data;

form a new trip based on the identified subsets of face data, ignition signal data, and driver change counter data, wherein the new trip is associated with face data of a specific driver; and

in the event that all trips of an album are associated with the specific driver that is also associated with the new trip, add the new trip to the album.

2. A system as in claim 1, wherein the processor is also configured to, in the event that all trips of an album are not associated with the specific driver that is associated with the trip, not add the new trip to the album.

3. A system as in claim 1, wherein the processor is also configured to form new albums using unassigned new trips, wherein an unassigned trip is a new trip that is not associated with an album.

4. A system as in claim 3, wherein a new album is formed in the event that a set of unassigned new trips is associated with a particular driver and the set of new trips has more than a threshold number of trips.

5. A system as in claim 4, wherein the set of new trips has high mutual similarity in associated face data between all pairs of trips in the set of trips.

6. A system as in claim 3, wherein the processor is also configured to form new albums using unassigned old trips.

7. A system as in claim 1, wherein the processor is also configured to associate an external identifier signal with the new trip.

8. A system as in claim 7, wherein the external identifier signal comprises a coached event.

9. A system as in claim 7, wherein the external identifier signal comprises a dispatch signal.

10. A system as in claim 7, wherein the external identifier signal is determined by checking a driver coaching event database.

11. A system as in claim 7, wherein the external identifier signal determined by checking a dispatch log database.

12. A system as in claim 7, wherein the external identifier signal is determined by checking an external identifier database.

13. A system as in claim 7, wherein the external identifier is associated with a vehicle.

14. A system as in claim 7, wherein the external identifier is associated with a time.

15. A method for passive driver identification, comprising:

receiving face data, ignition signal data, and driver change counter data;

identifying, using a processor, a subset of the face data, a subset of the ignition signal data, and a subset of the driver change counter data;

forming a new trip based on the identified subsets of face data, ignition signal data, and driver change counter data, wherein the new trip is associated with face data of a specific driver; and

in the event that all trips of an album are associated with the specific driver that is also associated with the new trip, adding the new trip to the album.

16. A computer program product for passive driver identification, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving face data, ignition signal data, and driver change counter data;

identifying, using a processor, a subset of the face data, a subset of the ignition signal data, and a subset of the driver change counter data;

forming a new trip based on the identified subsets of face data, ignition signal data, and driver change counter data, wherein the new trip is associated with face data of a specific driver; and

in the event that all trips of an album are associated with the specific driver that is also associated with the new trip, adding the new trip to the album.
