btkGetGroundReactionWrenches Class Reference

Description

Extract ground reaction wrenches (GRW) expressed in the global frame from a given acquisition.

Syntax:

grw = btkGetGroundReactionWrenches(h, threshold)

Parameters

h	Handle pointing to a C++ btk::Acquisition object.
threshold	Set all positions to (0,0,0) when the Fz value is lower or equal than the threshold

Return values

fpw

Paged structure with the following fields: fpw(i).P: Matrix (n,3) containing the positons of the wrench where n corresponds to the number of frames. fpw(i).F: Matrix (n,3) containing the forces of the wrench where n corresponds to the number of frames. fpw(i).M: Matrix (n,3) containing the moments of the wrench where n corresponds to the number of frames.
