Method and Apparatus for Decomposition of Quaternion for Minimizing Zero Crossing

摘要

Disclosed are a quaternion decomposition method for minimizing zero crossing and an apparatus therefor. A quaternion decomposition apparatus according to an embodiment of the present invention includes a data collection unit for obtaining input data; A quaternion data conversion unit that calculates a quaternion vector and a rotation angle based on some information of the input data and a nibble time; Based on the nibble time, one of the super complex planes is selected, and the quaternion vector ( ) And a first complex number projected based on the rotation angle ( ) A quaternion rotation processing unit that calculates; The first complex number based on the first plane rotor ( A first planar complex number calculator configured to calculate a first complex pair by rotating) in different directions; The first complex number ( A second planar complex number calculating unit for calculating a second complex pair by rotating) in different directions; And a quaternion decomposition symbol by selecting at least one of the first complex pair and the second complex pair ( , ) May include a multiplexer to be transmitted.
