Application of human facial features recognition to automobile security and convenience
First Claim
1. An imaging system for a vehicle, the imaging system comprising:
- an illuminator for illuminating a predefined field located outside of the vehicle and adjacent an entryway to an interior of the vehicle;
a detector for detecting radiation reflected from a person located in the predefined field, the detector being responsive to the detected radiation for providing image signals; and
a processor that is responsive to the image signals from the detector, the processor including face recognition software for analyzing the image signals for facial features of the person located in the predefined field, the processor comparing facial features of the person to known facial features of authorized vehicle occupants to determine whether the person is an authorized vehicle occupant, the processor causing the entryway to automatically become unlocked in response to a determination that the person is an authorized vehicle occupant,wherein the illuminator is also adapted to illuminate a predefined interior vehicle field and the detector is adapted to detect radiation reflected from an occupant of the vehicle that is located in the predefined vehicle interior field and to providing occupant image signals, the processor comparing facial features of the occupant image signals to the known facial features of authorized vehicle occupants and causing a vehicle operation to be performed in response to a facial feature match.

Abstract
An imaging system (50) for providing vehicle security and convenience features that employs face recognition software to identify and track a person. The system (50) employs infrared emitters (30) that emit an infrared signal along a predetermined field-of-view, and an infrared sensor (34), such as a CMOS sensor used as a video signal array, that receives reflected infrared illumination from objects in the field-of-view. A processor (52) including the face recognition software, is employed to detect human faces to identify and track the person. Once a face is detected, it can be compared to a data base to identify the person. Various applications for the imaging system (50) to provide driver convenience and security include determining driver identification as the driver approaches the vehicle, determining if a potential thief is in the vehicle by face recognition, providing driver seat adjustment, rear and side mirror adjustment and steering wheel adjustment, providing vehicle speed control, automatically starting the vehicle, etc.

12. An intruder detection system for a vehicle, the intruder detection system comprising:
-
an illuminator for illuminating an interior portion of the vehicle; a detector for detecting radiation reflected from a person located in the interior portion, the detector being responsive to the detected radiation for providing image signals indicative of an image of the person; and a processor that is responsive to the image signals from the detector, the processor including face recognition software for analyzing the image signals for facial features of the person, the processor comparing facial features of the person to known facial features of authorized vehicle occupants to determine whether the person is an authorized vehicle occupant, the processor sounding an alarm and recording the image of the person in a memory when the processor determines that the person is not an authorized vehicle occupant. - View Dependent Claims (13, 14, 15, 16)
