Method and apparatus for locating an object of interest within an image
First Claim
1. A method for identifying a position of an object of interest from a plurality of images, comprising the steps of:
- obtaining at least one image from each of a plurality of cameras, each camera having an associated perspective of a subject of interest;
translating image data from the plurality of images to produce at least one virtual image of a vehicle interior, each virtual image having a desired perspective different from that of the associated perspectives of the plurality of cameras;
locating candidate objects within the at least one virtual image; and
analyzing the candidate objects according to a heuristic voting algorithm to identify the position of the object of interest.

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 (220). A largest grouping of pixels in the side view image having values within a desired range is identified (230). 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 (240, 250, and 260). The contour peaks are analyzed according to a heuristic voting algorithm to identify a peak location associated with the head of the vehicle occupant (270).
