Hy-BIRD
Hy-BIRD fuses optical and inertial technologies into one compact tracking solution. Its primary optical technology outputs highly accurate, fast tracking data. A fully integrated inertial tracker seamlessly continues tracking whenever the optical scanner is blocked or its field of view exceeded.
- Fused data streams for flawless 360° tracking
- Wide operational temperature range for inertial sensors
- High speed tracking with minimal lag
- Robust inertial sensor with embedded microprocessor
FEATURES & BENEFITS
| Critical Features | Key Benefits |
|---|---|
| 240 optical measurements/second / 70-75 measurements/second in hybrid mode | Fast updates with no discernable lag |
| Full 360° coverage | no FOV limits |
| IR laser scanning technology with temperature compensated, calibrated inertial sensors | Accurate, undistorted tracking in fixed, motion-based and mobile environments |
| Built-in optical correction for inertial drift | Constant data flow without jumps or interruptions |
| Small footprint for emitter and detectors | Easy set-up with minimal impact on cockpit/vehicle real-estate |
| Fast, one-time calibration for misalignments | Flexible placement of optical and inertial sensors on helmet |
COMPONENTS
Hy-BIRD is composed of an optical scanning unit with embedded electronics (above) and two head-mounted sensors - optical and inertial. The optical sensor can be seen in the right foreground. Optical and inertial data streams are fused and transmitted to a host computer via a USB serial adapter.
