Gaze detection apparatus and the method of the same

Image Number 2 for United States Patent #8107688.

An image input unit, a feature point detection unit configured to extract at least four image feature points including a feature point of a pupil and which do not exist on an identical plane from an input image, a three-dimensional face model storage unit configured to store shape information of a three-dimensional face model and at least coordinates of reference feature points on the three-dimensional face model corresponding to the feature points extracted by the feature point detection unit, a converting unit configured to convert a coordinate of the feature point of the pupil onto surface of the three-dimensional face model on the basis of the correspondence between the extracted feature points and the reference feature points, and a gaze estimating unit configured to estimate the gaze direction from the converted coordinate of the pupil are provided.
