  • Patent number: 12125235
    Abstract: Disclosed herein is a system and method for obtaining and generating motion capture datasets relating to various working activities for ergonomic risk assessment. An example system may comprise a computing device that obtains first data from multiple motion capture cameras, obtains second data from multiple visible light imaging sensors, calculates 3D positions of multiple reflective markers positioned on several subjects performing various working activities based on the first data, labels each marker to generate marker trajectories, performs gap filing and smoothing functions on the marker trajectories to generate global marker positions, transforms the global marker positions into a corresponding image coordinate system of each sensor to generate 3D pose data of the subjects at each sensor viewpoint, projects the 3D pose data into frames of the second data to generate 2D pose data, and generates a dataset comprising the second data, the 2D pose data, and the 3D pose data.
    Type: Grant
    Filed: January 19, 2024
    Date of Patent: October 22, 2024
    Assignee: VelocityEHS Holdings Inc.
    Inventors: Julia Penfield, Leyang Wen, Veeru Talreja, Daeho Kim, Meiyin Liu, Richard Thomas Barker, SangHyun Lee
