THREE-DIMENSIONAL SHAPE MEASUREMENT METHOD OF HAND, THREE-DIMENSIONAL SHAPE MEASUREMENT INSTRUMENT, AND PROGRAM FOR THREE-DIMENSIONAL SHAPE MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional shape measuring method of a hand capable of expressing a three-dimensional shape of the whole hand nearly actual without a sense of incongruity in a three-dimensional shape.SOLUTION: An image processing part 14 of a three-dimensional shape measuring instrument of a hand includes: a shape measurement part 15 for executing a measuring step of calculating an upper side three-dimensional shape which is a three-dimensional shape of a back 2a side of one's hand on the basis of an imaged image using an optical cutting method; a shape estimation part 16 for executing the estimation step of estimating a lower side three-dimensional shape which is the three-dimensional shape of a palm 2b side of the hand not measurable from the back 2a of the hand; and a synthesis part 17 of executing a synthesis step of calculating the three-dimensional shape of the whole of the hand 2 by synthesizing the upper side three-dimensional shape obtained by the measurement and the lower side three-dimensional shape obtained by the estimation.SELECTED DRAWING: Figure 1
