# TF_DENORMALIZED_QUATERNION

I am using package of aruco from this link aruco ros when I change the matrix "rotate_to_ros" in "aruco_ros_utils.cpp" to be [1 0 0;0 0 1;0 1 0] I have the following error:

Error:   TF_DENORMALIZED_QUATERNION: Ignoring transform for child_frame_id "marker_frame" from authority "unknown_publisher" because of an invalid quaternion in the transform (-0.029012 -0.264665 -0.742686 0.526990)
