Unmanned aerial vehicle (UAV) systems have rapidly gained popularity in recent years due to their ability to perform various tasks in different fields. One of the essential features of UAV is the capability of autonomously navigating in unknown environments. Simultaneous Localization and Mapping (SLAM) is a technique used in robotics and autonomous systems to map an unknown environment while simultaneously determining the robot's position within it.
In UAV systems, SLAM is used to create a map of the environment by combining data from various sensors, including cameras, LiDAR, and GPS. The UAV navigates through the environment while simultaneously gathering information about its surroundings, creating a map that is continuously updated as it moves. The map can be used for various purposes, such as surveillance, inspection, and search and rescue operations.
The SLAM algorithm used in UAV systems typically involves a combination of feature-based and direct methods. Feature-based SLAM uses distinctive features in the environment, such as corners or edges, to create a map. Direct SLAM, on the other hand, uses the raw sensor data to create the map.
Overall, SLAM is an essential component of UAV systems, enabling them to navigate and map unknown environments autonomously. The advancements in SLAM technology have led to the development of more efficient and accurate UAV systems, which have numerous applications in various fields.
