GOLF SWING ANALYZER, GOLF SWING ANALYZING SYSTEM, GOLF SWING ANALYZING PROGRAM, RECORDING MEDIUM AND GOLF SWING ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a golf swing analyzer, a golf swing analyzing system, a golf swing analyzing program, a recording medium and a golf swing analyzing method capable of providing information by which natural swing can be analyzed.;SOLUTION: A golf swing analyzer 30 includes a joint torque calculation part 51 and a torque extraction part 52. The joint torque calculation part 51 constructs a double pendulum model 1 including a first link 11 corresponding to a region of an upper half of a golfer's body, a second link 12 corresponding to a golf club 26, and a joint part 13 connecting the first link 11 and the second link 12, and, based on an acceleration measured by an inertial sensor 21 attached to the golf club 26, calculates the joint torque F₂ that acts on the joint part 13 accompanying a swing motion. The torque extraction part 52 extracts the torque that generates a rotational motion around a predetermined axis to the second link 12 from the joint torque F₂.;COPYRIGHT: (C)2014,JPO&INPIT
