-### TF from coordinate A to coordinate B:
-
-In Orbbec cameras, the origin point (0,0,0) is taken from the camera_link position
-
-Our wrapper provide static TFs between each sensor coordinate to the camera base (camera_link)
-
-Also, it provides TFs from each sensor ROS coordinates to its corrosponding optical coordinates.
-
-Example of static TFs of RGB sensor and right infra sensor of Gemini335 module as it shown in rviz:
-
-```bash
-roslaunch orbbec_description view_model.launch.py model:=gemini_335_336.urdf.xacro
-```

-### 从坐标A到坐标B的TF变换：
-
-在奥比中光相机中，原点(0,0,0)取自camera_link位置
-
-我们的包装器提供从每个传感器坐标到相机基座(camera_link)的静态TF变换
-
-同时，它还提供从每个传感器ROS坐标到其对应光学坐标的TF变换。
-
-以下是Gemini335模块的RGB传感器和右红外传感器在rviz中显示的静态TF变换示例：

-```bash
-roslaunch orbbec_description view_model.launch model:=gemini_335_336.urdf.xacro
