  Motion capture - Wikipedia, the free encyclopedia
Motion tracking or motion capture started as an analysis tool in biomechanics research, and expanded into education, training, sports and recently computer animation for cinema and video games as the technology has matured.
Motion capture equipment costs from fifty thousand dollars for 8 camera active marker systems to millions of dollars for passive marker systems, for the digital video cameras, lights, software, and staff to run a mocap studio, and this technology investment can become obsolete every few years as better software and techniques are invented.
Motion capture technology is frequently used in digital puppetry systems to aid in the performance of computer generated characters in real-time.

 Motion Capture Research
Motion capture systems which involves the process of recording a live motion event and translating it into usable mathematical forms are now being widely used in many applications such as medicine (1-5), sports (6, 7), entertainment industry, and in the study of human factors (8).
Motion Capture is the process of recording a live motion event and translating it into usable mathematical terms by tracking a number of key points in space over time and combining them to obtain a single 3D representation of the performance [10].

And since the data is being captured in real time,it gives the director an opportunity to see it right away and make changes.Magnetic motion capture is ideally suited for situations in which the motionrange is limited and direct interaction between the actor, director, andcomputer character is important.interpolation after the motion has beencaptured.

 Motion Capture
I am less concerned with arguing for or against motion capture, or comparing it qualitatively to other animation techniques, than exploring its current state and (eventually) the way in which spectators in entertainment and fine art applications respond to figures based on 'realistic' motion capture data (that is, characters based on the performance of humans).
Motion capture (like computer animation, in general) is often touted as being both time- and money-saving, but actually it is not yet at the point where it is always a 'better deal' than traditional techniques.

Motion capture uses the real motion of a live performer to drive the animated motion of a 3D computer character.
We capture the face separately from the rest of the body, and record the actor’s voice during the facial capture session so that the animation’s lips are automatically synchronized with the sound.
After we have captured the facial and body motion, we use Kaydara Filmbox software to transfer the live performer’s body and facial movements onto the 3D model we have created of the historical performer.

 15-462 Assignment 3
Each frame in the motion can be treated as a node, and an edge is created between two nodes if the character's poses in the two frames are close enough.
In this assignment you are given a number of different motion data segments of a human walking, you should look for "good" transitions within each individual segment as well as for “good” transitions between different motion segments.
Because a character's pose is described by all of his/her joint angles and the position and orientation of his/her root node, a simple way to compare two poses is to calculate the sum of the distances between each joint angle and the position and orientation of the root node.

 IGN: House of Moves Motion Capture Interview
JP: Motion Capture or Performance Capture, as some call it, refers to the ability to "digitize" a performance of a live actor, athlete, animal, etc. The process is similar to filming although our cameras shoot at up to 240 frames per second.
It used to be that a 3D software company could simply put a motion importer in their software and tout "motion capture support." This approach no longer works as animators working with the data demand more "interactivity" and ability to customize or change motions (historically very difficult to do in most 3D packages).
We have captured motion for other film projects including the upcoming Mel Gibson film The Patriot which is directed by Roland Emmerich (of Independence Day and Godzilla fame).
