Project Background
  • 3D Motion Tracking Techniques
  • Mechanical
  • Optical Fibre
  • Acoustic
  • Magnetic
  • Optical
  • Optical Techniques need
  • High Performance computers
  • Optimised algorithms
  • Adequate Lighting
  • Optical Techniques offer contact-free operation

4
Aim
  • To create and evaluate a generic platform using
    optical sensor based inputs and image processing
    techniques, in order to capture the motion of any
    visible three-dimensional object, and securely
    distribute that information among hardware
    devices and software applications which will
    thereafter react to the motion of the target.

5
Objectives
  • Prepare a Terms of Reference
  • Conduct a Literature Survey
  • Feasibility Study and Requirement Analysis
  • Prototype Design
  • Prototype Implementation
  • Testing and Evaluation
  • Present the Prototype
  • Present an Interim Report
  • Present the final Report

Input from Literature
  • Why use
  • Optical Motion Tracking Techniques
  • RSA for secure communication
  • Communication with Hardware Devices
  • OpenGL for 3D Display
  • DirectInput for image capture

8
Analysis and Requirements Capture
  • Tracking of 3D objects
  • Reliance on Low-cost optical sensor based inputs
  • Provide location information to external devices
  • Secure client-server communication
  • A generic platform
  • Easy Deployment
  • User Authentication and customisable settings
  • Event Logging

Evaluation
  • Expert Evaluation using four user-groups
  • Academic
  • Software Engineering
  • Management
  • System Administration
  • Evaluation Criteria
  • The Solution
  • The Features offered
  • The Prototype
  • The Potential

14
The Future
  • Object Recognition Module
  • Cross-Protocol Communications Module
  • Data Compression in Communications
  • More than two cameras
  • Movable image sources
  • Integrating with other Motion Tracking techniques
  • Coordination between multiple MoTrack 3D Servers

15
Conclusion
  • Research, the true definition
  • Hardware is no longer a limitation
  • Vision Based 3D Motion Tracking is now more
    accessible to the Commercial and Academic Worlds
