Motion capture
Technology
Introduction• Motion capture is the process of recording human movement
through specialized camara’s and mapping them into a character model
• Motion capture technology involves sensing,digitizing,andrecording that object in motion
• It is also known as MO-CAP, Virtual, theater, Real-time animation or performance Animation
The Birth Of Motion Capture• Historically motion
capture in animated movies was created using the extension of “ROTOSCOPING” technique
•A Rotoscoping is a device that enables animation to trace live action movement,frame by frame,for use in animation
ROTOSCOPING
• Capture Video :
Rotoscoping works by first capturing a video of a real actor around props that resembles elements of scene
ROTOSCOPING
ROTOSCOPING• Tracing :
• Animation then
trace over each
frame of the
recorded video
this would result
in a figure that
moved in a very
realistic fashion
Post Processing :
Finally true animated figured would be colored and then integrated with various background layers to create the final shot
Mocap Techniques• Optical• Magnetic• Mechanical
Optical
Infrared camera
Marker Placement
• Location should move rigidly with joints
• Stay away from bulging muscles

• Entertainment• Medicine• Arts/Education• Science/Engineering
Entertainment : Live Action Films•Computer generated Characters in live action
films
Entertainment : 3D Computer animations
• Characters in computer animated films(eg.Avatar, The Dawn of The Planet of the Apes,Monster Heros)
• Video games by electronic Arts,Gremlin,id,RARE,Square,Kohami,Namco and other(eg. Enemy Territory)
Entertainment : video games
Medicine• Medicine(eg . Gait analysis,rehabilitation)• Sports medicine(eg . Injury prevention,performance
analyses,performance enhancement)
Gait analysis
Science/Engineering
•Engineering (eg. Biped robot developments)•Military (eg. Field exercises,Virtual
instructors,and role-playing games)
• Markerless MOCAP• Cheaper MOCAP• MOCAP as Input to large Display
Conclusion
• Motion Capture(MOCAP) is an effective 3D Animation tool for realistically Capturing human motion
