  • Publication number: 20200242344
    Abstract: From distance measurement data obtained by a distance measurement, according to a moving body approximate ellipses and quadratic functions along an xy-axis and yx-axis are calculated. An approximate ellipse close to the shoulder width and thickness of a user is selected, and quadratic functions having the smallest approximation error to the distance measurement data are selected. Thus, the position and orientation of the user are estimated from the selected approximate curves. That is, if an approximate curve based on one shape or coordinate system does not match the user, the position and orientation of the user are estimated from an approximate curve based on another shape or coordinate system. Therefore, even if the positional relation between the distance measurement sensor and user changes variously, the position and orientation of the user can be detected.
