INPUT DEVICE, FINGER-TIP POSITION DETECTION METHOD, AND COMPUTER PROGRAM FOR FINGER-TIP POSITION DETECTION

摘要

PROBLEM TO BE SOLVED: To provide an input device configured to detect a finger tip position in a real space, accurately.;SOLUTION: An input device includes: a finger area detection unit 11 which detects a finger area indicating a finger and a finger-tip position from the finger area, in one of a first image obtained by a first imaging unit imaging a finger and a second image obtained by a second imaging unit arranged at a predetermined distance from the first imaging unit to image the finger; a template setting unit 12 which sets a template including the finger area, and masks pixels in the template not included in the finger area; a collation unit 13 which determines a corresponding point of the other image corresponding to a finger-tip position on one image, by applying template matching between the template and one of the first and second images; and a finger-tip position calculation unit 14 which calculates a position of a finger tip in a real space, on the basis of the finger-tip position on the one image and the corresponding point on the other image.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
