My_ROV_WS is a ROS 2 setup that demonstrates how to integrate MediaPipe with camera, perception, and visualization nodes. Follow the steps below to install dependencies, build the workspace, and launch the application.

---

Install MediaPipe

Install the MediaPipe library:

cd ~/my_rov_ws
python -m pip install mediapipe

---

Build the Workspace

cd ~/my_rov_ws
colcon build

1. Source the Workspace

Before launching, source the workspace:

cd ~/my_rov_ws
source install/setup.bash

---

2. Launch the Nodes

Run the launch file to start all three nodes (camera_pkg, perception_pkg, and visualization_pkg):

ros2 launch camera_pkg camera_perception_viz.launch.py

---

Check Topics

List the active ROS 2 topics to confirm data is being published:

ros2 topic list

You should see topics like:

/camera/image_raw
/perception/output
/visualization/output
