  • 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.

  • Patent number: 10725283
    Abstract: An optical sensor that detects intensity of light is disposed, inside an optical case, at a position that allows the optical sensor to receive light other than light received by a lens system, out of light emitted by an LED. The optical sensor is housed in a dedicated photometric case. The photometric case is provided with a light guide portion that includes a transmission part and a shielding part. The transmission part is disposed in an optical path of light that directly travels from the LED to the optical sensor and allows transmission of the light. The shielding part blocks indirect light that is reflected or scattered inside the optical case, from entering the optical sensor. Accordingly, it is possible to accurately detect only the light in the direct optical path from the LED.
