Ros2 Vision Kit consists of packages to interface ROS with OpenCV and a library of Vision-based Algorithms that provide state of the art Detection, Segmentation and Tracking. Its main purpose is to provide Real-Time operations for ROS.
vision_bridge: A bridge between ROS 2 image messages and OpenCV image representation.image_geometry: Collection of methods for dealing with image and pixel geometry.ros2_vision_kit: A ROS meta-packege, used for grouping all loose packeges together. In this case, Vision_Bridge & Image_Geometry
