VZ4000
The VZ4000 tracker provides motion capture professionals with all the standard features of PTI trackers:
- 90° Operation Angle
- Huge Capture Area (7 m x 9 m) and space
- < 0.5 mm Accuracy (H-series)
- Automatic and Adaptive Calibration capability (with VZAutoCal)
- Instant and Continuous Calibration capability (with VZInstaCal, for flexible or moving environments)
The improved marker systems significantly boost the wireless motion
capture reliability even in radio-noisy environments.
Each VZ4000 tracker features a thermal-cycled rigid carbon composite
construction (for permanent calibration accuracy and stability) in a
lightweight aluminum shell. The elegantly designed custom aluminum
tripod also doubles as a heavy duty protective case during tracker
transportation.
