In this ROS2 tutorial, we explain how to interface a camera with ROS2 and OpenCV. We explain how to write publisher and subscriber nodes that will capture the image and display the image on the computer screen. The technique presented in this tutorial is very important for the development of robotic computer vision systems and for integrating computer vision systems with the ROS2 ecosystem.
The publisher node is running OpenCV. We use OpenCV to capture camera frames. The captured camera frames are resized and converted to the ROS2 image format. Images in ROS2 format become ROS2 messages. The messages are sent through an appropriate topic to the subscriber node. The subscriber node receives the messages and converts them to OpenCV image format. Then, the subscriber node shows the images on the computer screen.

worked like a charm in first run, thanks for it

Can you create a project video where you integrate OpenCV, voice recognition and face recognition to create a Ros reception bot

You are seriously doing great and making our job easier....Can you make some video how to integrate Arduino with Ros2....
