METHOD AND APPARATUS FOR GENERATING VIEWER FACE-TRACING INFORMATION, RECORDING MEDIUM FOR SAME, AND THREE-DIMENSIONAL DISPLAY APPARATUS

摘要

The present invention relates to a method and an apparatus for generating viewer face-tracing information, a recording medium for same, and a three-dimensional display apparatus, and the method for generating the viewer face-tracing information for controlling dimensionality of the three-dimensional display apparatus according to information on a gazing direction and/or a gazing distance of a viewer, comprising the steps of: (a) detecting a face region of the viewer from an image that is extracted from an image that is inputted through an image input means, which is provided on one position on a side of the three-dimensional display apparatus; (b) detecting facial characteristics from the face region which is detected; (c) estimating an optimal transformation matrix for generating a three-dimensional viewer face model, which corresponds to the facial characteristics, by transforming model characteristics of a three-dimensional standard face model; and (d) generating the viewer face-tracing information by estimating the gaze direction and/or the gaze distance of the viewer based on the optimal transformation matrix.
