+#### 使用 SDK bag 录制和回放
+
+SDK bag 会通过 Orbbec SDK 录制设备数据，适合后续用 wrapper 作为回放设备重新启动。启动时录制：
+
+```bash
+ros2 launch orbbec_camera gemini_330_series.launch.py bag_record_filename:=/tmp/orbbec_record.bag
+```
+
+也可以在节点运行时通过服务开始或停止录制：
+
+```bash
+ros2 service call /camera/set_bag_recording orbbec_camera_msgs/srv/SetBagRecording "{enable: true, file_path: '/tmp/orbbec_record.bag'}"
+```
+
+```bash
+ros2 service call /camera/set_bag_recording orbbec_camera_msgs/srv/SetBagRecording "{enable: false, file_path: ''}"
+```
+
+回放 SDK bag：
+
+```bash
+ros2 launch orbbec_camera gemini_330_series.launch.py bag_filename:=/tmp/orbbec_record.bag
+```
+
+如果需要循环回放：
+
+```bash
+ros2 launch orbbec_camera gemini_330_series.launch.py bag_filename:=/tmp/orbbec_record.bag bag_loop:=true
+```
