This paper presents a novel method for human head tracking using multiple cameras. Most existing methods estimate 3D target position according to 2D tracking results at different viewpoints. This framework can be easily affected by the inconsistent tracking results on 2D images, which leads 3D tracking failure. For solving this problem, we investigate a natural extension of Condensation to multi-viewpoint images. Our method generates many hypotheses on a target (human head) in 3D space and estimates the likelihood of each hypothesis by integrating viewpoint dependent likelihood values of 2D hypotheses projected on image planes. In theory, view point dependent likelihood values should be integrated by multiplication, however, it is easily affected by occulusions. Thus we investigate this problem and propose a novel integration method in this paper and implemented a prototype system consisting of six set of PCs and cameras. We confirmed the robustness against occulusions and the efficiency of our method. |
