+### point_cloud_detection
+
+点群から物体を検出して掴むコード例です。
+
+検出された物体位置はtfのフレームとして配信されます。
+tfの`frame_id`は検出された順に`target_0`、`target_1`、`target_2`…に設定されます。
+掴む対象はSciurus17前方の0.3 mの範囲にある`target_0`に設定されています。
+物体検出には[Point Cloud Library](https://pointclouds.org/)を使用しています。
+
+次のコマンドを実行します
+```sh
+ros2 launch sciurus17_examples camera_example.launch.py example:='point_cloud_detection'
