Motion Capture
Motion Capture
The process of translating human motion to a digital model
GamesFast AnimationMoviesBio Medical AnalysisVR
Types of Tracking
Facial trackingFull body trackingHand trackingPartial body tracking
Tracking Techniques
1- Mechanical Motion Capture
Exoskeleton, joints connected to angular encoderPros:
No interference, No occlusionReal timeLarge capture range
Cons:Freedom of movement is limitedMechanical failures
2- Magnetic Motion Capture
Magnetic sensors and a constant magnetic field generatorPros:
No optical occlusionSensor orientation is directly given
Cons:External interferenceSmall capture rangeWiring and batteries
3- Optical Motion Capture
Using markers (reflective or emitting)Uses light intensity to determine marker position
Pros:Free movementCapture range
Cons:Optical occlusionExtensive pre-processing and post-processingControlled lighting condition
4- Marker-less Tracking
Using computer visionDetect Humans in the pictureUses techniques to extract motion information from the image
Silhouette detectionJoint detection

Virtual Me
The Virtual Me Approach
A frame work for human motion captureColor based markersArbitrary number of camsDetect major limbs motion and orientationHopefully real time
Sample Application
Virtual GoalA simple game will be used as a demonstrationThe player will defend his goal from multiple ballsLimited translation motion
