pose_collinear() bool pose_collinear ( const Pose *  p1, const Pose *  p2, const Pose *  p3, double  ratio  ) Return true if the three values are collinear. Parameters [in] p1,p2,p3 Poses [in] ratio Value in [0,1] representing the duration of the timestamps associated to p1 and p2 divided by the duration of the timestamps associated to p1 and p3
