Slam scan to map

WebbThe SLAM algorithm processes this data to compute a map of the environment. The map is stored and used for localization, path-planning during the actual robot operation. This example uses a 2-D offline SLAM algorithm. The algorithm incrementally processes recorded lidar scans and builds a pose graph to create a map of the environment. WebbThis work proposes a feature-based SLAM framework using side-scan sonar, which is able to automatically detect and robustly match keypoints between paired side- scan images and uses the detected correspondences as constraints to optimize the AUV pose trajectory. Side-scan sonar (SSS) is a lightweight acoustic sensor that is frequently …
