Building on a highly efficient tightly coupled iterated Kalman filter, FAST-LIO2 has two key novelties that allow fast, robust, and accurate LiDAR navigation (and mapping). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. analyze the IoU for a set of 5 distance ranges: {(0m:10m), [10m:20m), [20m:30m), [30m:40m), (40m:50m)}. classes, they need to be passed through the learning_map_inv dictionary Download our recorded rosbag files (mid100_example.bag ), then: We provide a rosbag file of small size (named "loop_loop_hku_zym.bag", Download here) for demostration: For other example (loop_loop_hku_zym.bag, loop_hku_main.bag), launch with: NOTICE: The only difference between launch files "rosbag_loop_simple.launch" and "rosbag_loop.launch" is the minimum number of keyframes (minimum_keyframe_differen) between two candidate frames of loop detection. A tag already exists with the provided branch name. Contributors: Chunran Zheng Qingyan Zhu Wei Xu . Are you sure you want to create this branch?

Thanks for LOAM(J. Zhang and S. Singh. University of California, Santa Cruz, 2020. For large scale rosbag (for example, the HKUST_01.bag ), we recommand you launch with bigger line and plane resolution (using rosbag_largescale.launch). use numpy to directly write output in one pass. Please The LIO subsystem registers raw points (instead of feature points on e.g., edges or planes) of a new scan to an incrementally-built point cloud map. The feature extraction, lidar-only odometry and baseline implemented were heavily derived or taken from the original LOAM and its modified version (the point_processor in our project), and one of the initialization methods and the optimization pipeline from VINS-mono. [oth.] If you want to have more information on the leaderboard in the new updated Codalab competitions under the "Detailed Results", you have to provide an additional description.txt file to the submission archive containing information (here just an example): where name corresponds to the name of the method, pdf url is a link to the paper pdf url (or empty), and code url is a url that directs to the code (or empty). each scan into a 64 x 1024 image. to use Codespaces.
