Motion Capture

Definition: Recording of motion for immediate or delayed analysis and playback.
Developed to record animal and human locomotion.
- Still photography
- Video to High speed
- Motion capture marker systems.

2D STANDARD VIDEO:

PAL 50 hz (25 frames per second)
NTSC 60 hz (30 frames per second)

Standard video limitations:

- capturing of fast or critical events in movement often require faster capture rate of 25 frames (50hz).
- Human movement occurs in 3 planes.
- Cannot make decisions about motion from one view.
- cannot measure rotational movements.

3D Motion Analysis:

VICON Motion Analysis System:
- 2 or more cameras to reconstruct image into 3D.

Used by:
- Sports biomechanists
- Clinical Biomechanists
( Cereberal palsy, ACL injuries, osteoarthritis, amputees)
- Animal biologists
- Industry
- Film, TV & animation
