The method includes: measuring a maximum output of a free end of the second rod in at least one predetermined direction; measuring orbiting outputs of the free end of the second rod in all directions in the plane; and creating a hexagonal maximum output distribution corresponding to a contribution amount of each muscle of the muscle group model based on the maximum output in the predetermined direction and the orbiting outputs.

Abstract: Provided are an analysis device, an analysis method, a program, and a calibration method. The analysis device includes: an obtaining part obtaining an image captured by an image capturing part that captures an image of one or more first markers provided on an estimation target; and a calibration part calibrating a conversion rule from a sensor coordinate system to a segment coordinate system based on the image. A posture of the first marker relative to at least one inertial measurement sensor does not change, and the posture with respect to the image capturing part is recognizable by analyzing the captured image. The calibration part derives the posture of the first marker with respect to the image capturing part, derives a conversion matrix from the sensor coordinate system to a camera coordinate system based on the derived posture, and calibrates the conversion rule by using the derived conversion matrix.

Abstract: A muscular strength characteristic evaluation method evaluates a muscular strength characteristic of a limb 3 including a first rod L1 having a base end supported by a first joint Ji, and a second rod L2 supported by a free end of the first rod via a second joint J2. The muscular strength characteristic evaluation method includes the following steps. In Step ST1, a free end of the second rod is moved at two or more different velocities va, vb, and vc in a predetermined direction, and an output at the free end of the second rod is respectively measured at a predetermined position O. In Step ST2, a function indicating a relationship between the output and the velocity in a direction is calculated based on the output and the velocity. In Steps ST3 and ST4, the muscular strength characteristic is evaluated based on the function.
