BioStage

Scanning

• Scan Space – up to 4m x 4m x 2.5m; 12ft x 12ft x 7.5ft
• 60-120fps, real-time with approximately 25-100ms latency
• XYZ Positional Accuracy (arms, legs) up to 1.0mm
• Rotational Accuracy (arms, legs other than along axis) up to 1°
• Rotational Accuracy (along axis) up to 2°
• Bones: 21 bones – 6 degrees of freedom each
• Tracks one Subject (Two Subject expansion Module available 2008)
• Prop Tracking via a substitute prop included (Upgrade in 2008)
• Designed for indoor use in typical artificial and/or natural lighting

Equipment

• Vision Processor
• 10 Cameras: 120fps, gray scale
• Resolution equivalent to 2 mega pixel of marker-based system, high speed NTSC actual
• Cameras can synch and genlock with external timecode at 120fps and slower
• Scalable Scaffolding and reflective cloth to create scan space
• All connection cables

Software

• Biomechanical Plug-in: flows data real-time into The MotionMonitor from Innovative Sports Technology, Inc. and Visual3D from C-Motion, Inc.
• Software Development Kit (SDK) available
• Two Subject and Finger Tracking expansion Modules (early 2008)
• Ankle/Foot Tracking expansion Module (mid 2008)
• Prop Tracking Upgrade – Prop is tracked by applying pattern (early 2008)

Output Format

• Supported through Visual3D and SDK, exports ASCII; inquire for specific formats
• 3D mesh variable from 500 to 8,000 triangles
• Surface texture via video

Calibration

• Lens Calibration: lens distortion is pre-calibrated prior to shipping
• System Calibration: On site in approximately 3 minutes – via a pattern board (provided)
• Subject Calibration: On site in approximately 1 minute – BioStage auto-learns after first 'acquisition' of Subject
