The present invention is a coordinate transformation method characterized by carrying out a procedure to: acquire three-dimensional skeletal information of a subject in motion who is described under a first coordinate system comprising a x' direction, a y' direction, and a z' direction, which are mutually orthogonal; use the skeletal information to calculate a Y direction being the traveling direction of the subject, a Z direction along the torso of the subject, and a X direction orthogonal to the Y direction and the Z direction; and transform the first coordinate system into a second coordinate system comprising the X direction, the Y direction, and the Z direction."
The patent application was internationally filed on Feb. 13, 2024, under International application No.PCT/JP2024/004768.
