ORB-SLAM

ORB-SLAM is a technology used in robotics and computer vision that helps machines understand their surroundings by tracking movement and creating 3D maps. It uses special keypoints called ORB (Oriented FAST and Rotated BRIEF) features to recognize objects and locate themselves in the environment. As a camera captures images, ORB-SLAM analyzes these to detect changes, allowing the system to map areas and navigate through them effectively. This method is effective in real-time, making it useful for applications like autonomous drones, self-driving cars, and augmented reality.
