<P>PROBLEM TO BE SOLVED: To provide a three-dimensional observation state measuring apparatus which enables the accurate measurement of the strained condition of the eyes by measuring the three-dimensional observation state of the eyes when the audiovisual users observe a natural three-dimensional object. <P>SOLUTION: The apparatus is provided with an image acquisition part 20 which acquires the stereoscopic images containing the directions of the line of vision, a coordinate acquisition part 22 which acquires the three-dimensional coordinate values of the observation object 10 in the directions of the line of vision involved based on the stereoscopic images obtained at the image acquisition part 20, a vision line direction detection part 30 which detects the directions of the line of vision of the eyes 14 to be examined, a notice point position measuring part 32 for determining the positions of the notice points of the eyes 14 to be examined from the lines of vision detected by the direction of vision line detection part 30 and a coordinate comparison part 40 which compares the position of the line of vision obtained at the notice point position measuring part 32 with the coordinate value of the notice point of the observation object 10 in the direction of the line of vision at the point of determining the position of the notice point. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
