<p>PROBLEM TO BE SOLVED: To provide the instrument and method for three-dimensional position measurement of a moving object which can easily and speedily discriminate the same marker. SOLUTION: The instrument which measures the three-dimensional position of the moving object by using markers fitted at many positions of the moving object 100 includes the markers 102 which are stuck on the moving object and radiate or reflect lights of mutually different colors, at least two color cameras 104, 106, and 108 which pick up images of the object with the markers, and an image process part 110 which discriminates markers of mutually different colors from at least two images picked up by the color cameras at the same time and calculates the three-dimensional position of the moving object from the image position of the marker having the same color between at least two images. Consequently, the respective markers are discriminated according to the colors of the markers stuck on respective objects by using the color images, so the same marker in mutually different images can easily and speedily be discriminated.</p> |
