MVN MotionGrid

MVN MotionGrid is a position aiding system for Xsens MVN. MotionGrid enables real-time driftless multi-person recording. The portable system can be used indoors and outdoors. With a minimal amount of hardware and quick calibration, MotionGrid is a flexible and cost effective system.

 

MVN MotionGrid

MVN MotionGrid is an UWB based tracking technology complementary to Xsens’ inertial based motion tracking Xsens MVN system. MotionGrid is essentially adding the equivalent of a local GPS system to Xsens’ MVN full body motion capture system. Large capture volumes of 20x20m (60x60ft) can be easily realized using the default 9-reader MotionGrid configuration. MVN MotionGrid is based on UWB RF technology and therefore does not require line of sight or special lighting conditions.

“Speed of turnaround is crucial to us: MVN MotionGrid makes our pipeline faster and more cost efficient”.
Mike Romey, Pipeline Supervisor at Zoic Studios
