Abstract
Systems and methods are provided for identifying a position of a head of a vehicle occupant from a plurality of images of a vehicle interior. Image data is translated from the plurality of images to produce a virtual side view image of the vehicle interior (162). A largest grouping of pixels in the side view image having values within a desired range is identified (164). The grouping includes a plurality of pixel columns. A contour including uppermost pixels of each pixel column is produced and peaks are located within the contour (166). The contour peaks are analyzed according to a heuristic voting algorithm to identify a peak location associated with the head of the vehicle occupant (172).
