| Abstract(in English) | This paper presents an approach for estimating 3D rigid head position and orientation from monocular, non-calibrated image sequences. The proposed method relies on a 2D/3D matching between the image-based tracking of at least two feature points on the face and a 3D rigid representation of these points. Possible 3D object motions are constrained to fit hypothetical rigid head motion trajectories relative to the torso. These modeled trajectories comprise only 3 degrees of freedom extracted by Principal Component Analysis of accurate head orientations obtained with OPTOTRAK. Thus, for the 2D tracked positions of each image, a unique estimation of head pose is computed. The estimation results have been validated using OPTOTRAK data obtained simultaneously with the video. |
