この前、 @AriYumotoman_calibのプログラムを修正しに来てくれました.
その際に,

TF_DENORMALIZED_QUATERNION: Ignoring transform for child_frame_id "fixed_kinect_frame" from authority "unknown_publisher" because of an invalid quaternion in the transform (-0.074733 0.036896 0.843233 0.531062)

というエラーがプログラムの実行時に出ており,結果としてfixed_frame_kinectがPublishされないという問題がありました.

そこで b497313 の変更で,対象になっているquaternionの正規化を行ったところ,エラーが解消されました.
しかし,今度は

[ WARN] [1494844934.110699316]: TF to MSG: Quaternion Not Properly Normalized

というWarningが出るようになりました.
また,Publishされるfixed_frame_kinectの位置・姿勢も実際のものとは大きくずれています.
上記の問題を解決次第本issueは閉じます.
