Hiroki Higa, Kazutoshi Tsuha, Ryota Onaga, Ikuo Nakamura · 2006
In this paper, an image processing method using CMOS camera was applied to an assistive system to care for bedridden people. It was experimentally demonstrated that 2-dimensional position tracking of the experimental subject's mouth was performed using image processing. Furthermore, 3-dimensional position tracking of the subject's mouth was measured using stereo matching measurement. From the experimental results, it was clear that the 2-dimensional position of his mouth was correctly tracked 90 % in all frames, and that the 3-dimensional position tracking of his mouth was effectively measured.
