PROBLEM TO BE SOLVED: To provide a method and device for measuring movement in both of vertical and horizontal planes in a golf club or general exercise tools with a single camera and particularly making head movement, a blow angle and a trajectory of the golf club head in a golf swing to be easily measured. SOLUTION: A velocity v in a primary movement direction and a head speed HS, separately measured, measure a position in a depth direction of the golf club head or another object to be measured, thereby acquiring image coordinate values of a calibration point with calculations to enable two-dimensional space coordinates of the objective point to be measured in a position apart from a calibration plane to be measured.
