generation-snowflake/tank_robot_camera

This ROS 2 package streams webcam images from a publisher node to a subscriber node, which detects colored regions and displays their contours. The publisher periodically reads the default camera, converts frames to ROS image messages, and publishes them; the subscriber converts received messages back to OpenCV frames before processing them. The README documents running each node separately. The graph reflects the sampled node code; it does not assume other camera settings or processing stages.
