Method and program product for multi joint tracking combining embedded sensor and external sensor

摘要

The method and program product includes assigning a first location of at least one embedded device. The embedded device includes at least one sensor and is associated with one joint that is movable. The first position is captured by the sensor. A second location of at least one embedded device is assigned. The second position is captured by observation of the embedded device with at least one external sensor. A pose correspondence between the first position and the second position is established using a model of the joint. The sensor is calibrated by tracking the pose changes captured by the external sensor and the pose changes captured by one sensor as the joint moves.
