  • Patent number: 11461905
    Abstract: Implementations generally relate to determining a kinematic sequence. In some implementations, a method includes obtaining a video of a person performing an action. The method further includes determining from the video a plurality of points associated with the person, where the determining of the plurality of points is performed for each frame of the video. The method further includes converting two-dimensional (2D) coordinates of the plurality of points to three-dimensional (3D) coordinates, where the converting is performed for each frame of the video. The method further includes determining a movement of the plurality of points based at least in part on the 3D coordinates.
    Type: Grant
    Filed: September 20, 2019
    Date of Patent: October 4, 2022
    Assignee: Sony Group Corporation
    Inventors: Jong Hwa Lee, Brent Faust, Kenji Suzuki, Arun Chandrasekar, Joseph Moon, Xihe Zhang
  • Patent number: 11222428
    Abstract: Implementations generally relate to determining golf swing characteristics. In some implementations, a method includes obtaining a video of a person performing an action. The method further includes determining from the video a plurality of points associated with the person, where the determining of the plurality of points is performed for each frame of the video. The method further includes determining a plurality of three-dimensional (3D) coordinates for each point of the plurality of points, where the determining of the 3D coordinates is performed for each frame of the video. The method further includes determining a movement of the plurality of points based at least in part on the 3D coordinates. The method further includes determining one or more movement errors based at least in part on the movement of the plurality of points.
