Vehicle occupant position sensor utilizing image focus attributes |
摘要 |
A vehicle occupant sensor apparatus (34) has an imager (36) that gathers an image of an occupant (12). The image has focus attributes. A focal plane associated with the imager (36) is at a distance from the imager. A 2D high-pass filter (42), a multiple frame temporal filter (46), and a position determination component (52) operate to determine position of the occupant (12) relative to the focal plane (38) via use of the focus attributes.
