A New Accurate Method of 3D Full Body Motion Capture for Animation


Stanford Reference:

05-433


Abstract


Stanford researchers have patented a unique approach for accurate and precise unencumbered 3D movement analysis for full motion 3D animation.

The system architecture is modular and includes:
1. Multiple synchronized cameras acquisition
2. Foreground/Background segmentation
3. 3D representation reconstruction
4. Tracking of the representation through a model
5. Kinematics extraction and outputting
This invention works with the model generation methods and software described in Stanford docket S07-254, S07-086, and US Patent 8,180,714.
This markerless motion capture system is accurate enough for biomechanical, clinical, sports, animation, video gaming, design, ergonomics, and surveillance applications.

Applications


  • Initially developed for biomechanical and clinical uses but can also be used for:
    • Sports performance evaluation or sports medicine
    • Animation and computer graphics
    • Digital movies
    • Interactive gaming and video games industry
    • Biofeedback and rehabilitation
    • Design and engineering
    • Ergonomics
    • Visual arts and any art using biological signals as an input or output
    • Robotics - development of biomimetic robots
    • Surveillance

Advantages


  • Accurately and precisely measures three-dimensional kinematics of the dynamically moving object or human.
  • Simple and time-efficient
  • Markerless - No requirement for the placement of any device or object on the subject’s body
  • Low cost – uses off the shelf cameras, no custom hardware required
  • Many data points - Synchronizes video streams from different views that maximize the amount of information made available by the system
  • Can operate in outdoor conditions and does not require a specific controlled environment
  • Does not require a specific protocol set up
  • Provides straightforward full body kinematics
  • Broad applications
