OMMotus™ Optical Motion Capture System
An optical motion-capture system for comprehensive movement biomechanics analysis. Its high-resolution optical capture combines long range, high accuracy and low latency to track multiple subjects in complex scenes. Streamlined operation and analysis software processes data through FPGA edge computing to output high-precision six-degrees-of-freedom data. The system synchronizes with force plates, pressure walkways, wireless surface EMG and Visual3D biomechanics software, with synchronization latency under 50µs for accurate, reliable data.

Features
- Ultra-low latency, ultra-high frame rate: up to 380 fps at full resolution with latency as low as 2.63 ms to capture fine movement detail
- High accuracy: a calibration algorithm requiring minimal prior information reaches sub-20µm precision under optimal conditions
- Wide field of view: a proprietary lens-distortion-correction algorithm delivers an 89°×49° FOV at high frame rate and low latency without sacrificing accuracy
- Stable and interference-resistant: invisible 850nm infrared illumination with drift-free tracking, robust against light, vibration, noise and electromagnetic interference
