2022-01-27 03:35:43 -0500 | marked best answer | slam_toolbox for general case SLAM and localization Scenario: I have a very large indoor area with multiple large rooms that are dynamic in the sense that objects may change position and I want to create its map periodically in order to localize multiple robots. Probably I’m describing the most complex scenario possible. LiDAR measurements and odometry are available and multiple robots can be used for mapping. My strategy to capture the aforementioned dynamicity is the use of multiple robots that will create separate maps frequently and then merge them. Solution and "hiccup:" I would like to use slam_toolbox for ROS1 Noetic for mapping since it seems to be more robust than its "competitors". Once a SLAM session has been finished, slam_toolbox serializes and saves poses and graph data into a file. This great toolbox includes offline map merging functionality that does not fulfill my needs. More specifically, it creates an occupancy grid of all the maps combined, but it does not update appropriately the Karto::Mapper object i.e. the internal graph used to perform localization. According to the code and the README file, it seems that the merged occupancy grid can be used to generate an ordinary image (pgm) map that can be then used for localization e.g. with AMCL. Questions: Based on your experience with slam_toolbox:
Based on your answers and your experience I am thinking of different solutions and possible developments. |
