Motion Tracking with Reduced On-Body Sensors Set

摘要

A method of tracking the motion of a moving object having a plurality of linked segments is provided. The method uses a limited set of sensing units that are coupled to one or more of the segments to receive one or more sensor signals from the sensing units. Based on the sensor signals, the method estimates a 3D orientation and predicts a 3D position of the segments at a tracking module. The method further communicates the 3D orientation and the 3D position of the segments to a database module, and associates a pose of the object to the 3D orientation and the 3D position of the segments.

1. A system for tracking motion of a moving object having a plurality of linked segments, the system comprising:
a limited set of sensing units coupled to a subset of the segments and configured to generate sensor signals corresponding to one or more features of the segments; a tracking module in communication with the sensing units, the tracking module being configured to determine at least a 3D orientation and a 3D position of the segments based on the sensor signals; and a database module in communication with the tracking module, the database module being configured to associate a pose of the object with the 3D orientation and the 3D position of the segments.
