ros2 vision_opencv contains packages to interface ROS 2 with OpenCV which is a library designed for computational efficiency and strong focus for real time computer vision applications. This repository contains:

• cv_bridge: Bridge between ROS 2 image messages and OpenCV image representation
• image_geometry: Collection of methods for dealing with image and pixel geometry
• opencv_tests: Integration tests to use the capability of the packages with opencv
• vision_opencv: Meta-package to install both cv_bridge and image_geometry

In order to use ROS 2 with OpenCV, please see the details within cv_bridge package.
