1. A method for real-time driver state monitoring comprising:

  • operating an image processing system to receive a sequence of depth images from a depth sensor, each depth image comprising image data representing an image of a scene, wherein said image data comprises a depth value indicating distance from the depth sensor;

    the image processing system identifying a human head in the scene using the sequence of images;

    the image processing system using the depth images to track position and orientation of the human head with respect to a principal position and orientation where the human head is modeled as a 3D surface to define a head model and continuously adapted over time to obtain an average neutral face model;

    the image processing system identifying depth deviations from the neutral face; and

    the image processing system classifying such depth deviations as different driver states.
