Abstract

A vehicle includes a pair of cameras disposed on the vehicle and oriented to view an entrance to the vehicle. The vehicle also includes a processor configured to compare a profile image of a passenger'"'"'s facial feature from one of the pair with a frontal image of the passenger'"'"'s facial feature from the other of the pair. The processor is configured to lock the entrance to the vehicle in response to the facial features being different.

Claims

1. A vehicle comprising:

a pair of cameras disposed on the vehicle and oriented to view an entrance to the vehicle; and

a processor configured to compare a profile image of a passenger'"'"'s facial feature from one of the pair with a frontal image of the passenger'"'"'s facial feature from the other of the pair, and in response to the facial features being different, lock the entrance to prevent access to an interior of the vehicle by the passenger.

2. The vehicle of claim 1, wherein one of the pair is disposed on a side view mirror of the vehicle and the other of the pair is disposed in a passenger cabin of the vehicle.

3. The vehicle of claim 1, wherein the processor is further configured to generate a three dimensional model of the facial feature using the profile image and frontal image, wherein the facial features are different when the three dimensional model is invalid.

4. The vehicle of claim 1, wherein the facial feature is a nose.

5. The vehicle of claim 1, wherein the facial feature is a chin of the passenger.

6. A vehicle comprising:

a pair of cameras disposed on the vehicle and oriented to view an entrance to the vehicle from different aspects; and

a processor configured to compare a profile image of a passenger from one of the pair with a frontal image of the passenger from the other of the pair, and in response to the front and profile images corresponding to different shapes for a same facial structure, disable the vehicle.

7. The vehicle of claim 6, wherein the processor is further configured to lock the vehicle after the passenger enters.

8. The vehicle of claim 6, wherein the processor is further configured to sound an alarm of the vehicle in response to the front and profile images corresponding to different shapes for the same facial structure.

9. The vehicle of claim 6, wherein the facial structure is an eye socket of the passenger.

10. The vehicle of claim 6, wherein the facial structure is a cheek structure of the passenger.

11. The vehicle of claim 6, wherein the facial structure is an eye color of the passenger.

12. A vehicle comprising:

a processor configured to, in response to a visual detector having a pair of cameras disposed in the vehicle and oriented to view an interior of the vehicle from different aspects recognizing an object in images taken by the pair after a passenger exits the vehicle and to a mass detector having a scale disposed in the vehicle sensing a weight of the object after the passenger exits the vehicle, provide notification to the passenger that the object was left in the vehicle.

13. The vehicle of claim 12, wherein the notification is an electronic message.

14. The vehicle of claim 13, wherein the electronic message is an SMS message.

15. The vehicle of claim 13, wherein the electronic message is sent over vehicle 802.11 communication protocols.

16. The vehicle of claim 12, wherein the object is a cellular phone.

17. The vehicle of claim 16, wherein the notification is an audible alarm in response to the object being a cellular phone.

18. The vehicle of claim 12, wherein the visual detector performs edge detection on all objects in a field of view of the pair.

19. The vehicle of claim 18, wherein the visual detector verifies objects recognized from the pair.

20. The vehicle of claim 18, wherein the field of view is of an area measured by the scale.
