<p><P>PROBLEM TO BE SOLVED: To provide a motion tracker device capable of reliably identifying each optical marker without causing the optical marker to have identification information or to emit light one by one in turn. <P>SOLUTION: The motion tracker device 1 includes: an object angular velocity detection sensor 4 detecting an object angular velocity acting on an object 10 in a short time; an object acceleration detection sensor 5 detecting an object acceleration acting on the object 10 in a short time; a first coordinate system angular movement calculation part 23 calculating an angular movement of a first coordinate system; a first coordinate system position movement calculation part 27 calculating a position movement of the first coordinate system; and an optical marker estimation part 26 estimating a predicted movement position of the optical marker on the basis of optical marker location information, the angular movement of the first coordinate system, and the position movement of the first coordinate system. An optical marker location information calculation part 24 identifies three or more optical markers 7 individually on the basis of the predicted movement positions of the optical markers. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
