SLAM, or Simultaneous Localization and Mapping, is a computational technique used in robotics and autonomous systems to build a map of an unknown environment while tracking the system’s location within it. Sensor integration enhances SLAM by combining data from multiple sources such as cameras, LiDAR, GPS, and inertial measurement units (IMUs).
This approach exists because relying on a single sensor often leads to limitations such as noise, inaccuracies, or failure in complex environments. By integrating multiple sensors, systems can achieve more accurate and reliable navigation.
SLAM with sensor integration is widely used in autonomous vehicles, drones, industrial robots, and smart devices. It helps machines understand their surroundings in real time, even in dynamic or unfamiliar environments.
