The document discusses motion capture production. It defines motion capture as sampling and recording the motion of humans, animals, and objects as 3D data. It then lists some common applications of motion capture such as film/animation, video games, medical, and military. The document goes on to provide a brief history of motion capture, showing some early examples. It also showcases different motion capture systems including optical, magnetic, and mechanical systems. It provides details on how each system works and their advantages.

2. Motion capture (Mocap) is sampling and
recording motion of humans, animals, and
inanimate objects as 3D data.

22. 1. Optical Mocap Systems
2. Magnetic Mocap Systems
3. Mechanical Mocap Systems

23. 1. Designed for medical application
2. Developed with CGI application – Vicon 8 system.
3. 4 to 32 cameras controls by computer.
4. Subject wears markers (Active & Passive).

25. 1. Magnetic Trackers.
2. Derived from the sensors placed on military aircraft pilots helmet to
track the pilot head position and orientation for the helmet-mounted
display.
3. 12-20 tracking sensors are placed on a captured subject.
4. Tracking sensors output their translation and orientations.
5. Divide into two groups
1. Direct Currant (DC)
2. Alternating Currant (AC)

27. 1. Directly Measure joint angels of a capture subject.
2. Designed to measure joint angles as the capture moves.
3. Device look like an exo-skeleton.
4. Mechanical system are real time, relatively
inexpensive, free of occlusion, free from magnetic or
electrical interference and highly portable.
5. Wireless mechanical system.
