Operator determination device and operator determination method

Abstract

To provide an operator determination device and an operator determination method capable of improving the determination accuracy of an operator.SOLUTION: An operator determination device 1 is roughly configured by comprising: an acquisition unit that acquires an image 101; a skeleton coordinate calculation unit 12 that calculates a plurality of skeleton coordinates 120 on the basis of the acquired image 101; a reference coordinate calculation unit 14 that calculates reference coordinates 140 of a finger image 900 on the basis of the skeleton coordinates 120; a reference coordinate update unit 16 that searches for a pixel 102 having a coordinate value separated by a predetermined distance α from the reference coordinates 140 in the image 101, updates the coordinates of the pixel 102 of an arm image 910 as the reference coordinates 140 when the pixel 102 of the arm image 910 linked with the reference coordinates 140 is present, and repeats this search by a predetermined number of times; and a control unit 20 that determines on which of a driver seat 80 and a front passenger seat 81 an occupant 9 operating the operation device is sitting on the basis of updated update reference coordinates 160.SELECTED DRAWING: Figure 4
