Blind Spot Detection Systems And Methods
First Claim
Patent Images
1. A method comprising:
- detecting, by a primary vehicle, a secondary vehicle ahead of the primary vehicle;
receiving an image of the secondary vehicle from a camera mounted to the primary vehicle;
identifying a side-view mirror in the received image;
analyzing an image within the side-view mirror to determine a head position of a secondary vehicle driver; and
determining whether the driver can see the primary vehicle based on the head position of the driver.

Abstract
Example blind spot detection systems and methods are described. In one implementation, a primary vehicle detects a secondary vehicle ahead of the primary vehicle in an adjacent lane of traffic. A method determines dimensions of the secondary vehicle and estimates a vehicle class associated with the secondary vehicle based on the dimensions of the secondary vehicle. The method also identifies a side-view mirror location on the secondary vehicle and determines a blind spot associated with the secondary vehicle based on the vehicle class and the side-view mirror location.

1. A method comprising:
-
detecting, by a primary vehicle, a secondary vehicle ahead of the primary vehicle; receiving an image of the secondary vehicle from a camera mounted to the primary vehicle; identifying a side-view mirror in the received image; analyzing an image within the side-view mirror to determine a head position of a secondary vehicle driver; and determining whether the driver can see the primary vehicle based on the head position of the driver. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A method comprising:
-
detecting, by a blind spot detection system in a primary vehicle, a secondary vehicle ahead of the primary vehicle in an adjacent lane of traffic; receiving an image of the secondary vehicle from a camera mounted to the primary vehicle; identifying a side-view mirror in the received image; analyzing the image within the side-view mirror to determine whether a face of a driver of the secondary vehicle is visible within the side-view mirror; determining whether the driver of the secondary vehicle is likely to see the primary vehicle based on the head position of the driver of the secondary vehicle; and alerting a driver of the primary vehicle responsive to determining that the secondary vehicle driver cannot see the primary vehicle. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
an image processing module configured to detect a secondary vehicle ahead of a primary vehicle, the image processing module further configured to receive an image of the secondary vehicle from a camera mounted to the primary vehicle; a vehicle mirror detector configured to identify a side-view mirror in the received image; and a facial analysis module configured to analyze an image within the side-view mirror to determine a head position of a driver of the secondary vehicle, the facial analysis module further configured to determine whether the driver of the secondary vehicle can see the primary vehicle based on the head position of the driver. - View Dependent Claims (20)
