Loop Closure Detection

Loop closure detection is a process used in robotics and navigation to recognize when a system returns to a previously visited location. Imagine walking through a city and realizing you've come back to a street you walked earlier. In this context, loop closure helps ensure that the system accurately updates its map and understands its surroundings, preventing errors in distance and direction. This is crucial for ensuring the robot or vehicle can effectively plan its route, improve its map accuracy, and avoid getting lost. It enhances the reliability of navigation in both known and unknown environments.
