HYBRID POSE TRACKING SYSTEM WITH ELECTROMAGNETIC POSITION TRACKING

摘要

A device [100] uses a hybrid pose tracking system, whereby the hybrid pose tracking system includes both an EM pose tracking system and a secondary pose tracking system [117, 118], such as a line-of-sight pose tracking system. The hybrid pose tracking system collects EM pose data from the EM tracking system indicating a relative pose between a transmitter [110] and a receiver [120], and further collects from the secondary tracking system secondary pose data that is also indicative of the pose of either the transmitter or the receiver. The hybrid pose tracking system calculates a weighted combination (e.g., a weighted sum) of the EM pose data and the secondary pose data to generate a final pose for the device.
