Map-based Localization

Map-based localization is a method used by robots or autonomous vehicles to determine their exact position within an environment by referencing a pre-existing map. It involves comparing real-time sensor data—like camera images or lidar scans—with the detailed map stored beforehand. By matching current observations to the map, the system can accurately pinpoint where it is, much like how a GPS device uses satellite signals to locate a position. This process helps the vehicle understand its surroundings, navigate safely, and perform tasks effectively.
