LIO-SAM - LIO-SAM: Tightly-coupled Lidar Inertial Odometry via Smoothing and Mapping

  •    C++

A real-time lidar-inertial odometry package. We strongly recommend the users read this document thoroughly and test the package with the provided dataset first. A video of the demonstration of the method can be found on YouTube.

depth_clustering - :taxi: Fast and robust clustering of point clouds generated with a Velodyne sensor

  •    C++

This is a fast and robust algorithm to segment point clouds taken with Velodyne sensor into objects. It works with all available Velodyne sensors, i.e. 16, 32 and 64 beam ones. I recommend using a virtual environment in your catkin workspace (<catkin_ws> in this readme) and will assume that you have it set up throughout this readme. Please update your commands accordingly if needed. I will be using pipenv that you can install with pip.

LeGO-LOAM - LeGO-LOAM: Lightweight and Ground-Optimized Lidar Odometry and Mapping on Variable Terrain

  •    C++

An updated lidar-initial odometry package, LIO-SAM, has been open-sourced and available for testing. You can use the following commands to download and compile the package.

loam_velodyne - Laser Odometry and Mapping (Loam) is a realtime method for state estimation and mapping using a 3D lidar

  •    C++

Ask questions here. Issues #71 and #7 address this problem. The current known solution is to build the same version of PCL that you have on your system from source, and set the CMAKE_PREFIX_PATH accordingly so that catkin can find it. See this issue for more details.




lidar_camera_calibration - ROS package to find a rigid-body transformation between a LiDAR and a camera for "LiDAR-Camera Calibration using 3D-3D Point correspondences"

  •    C++

The package is used to calibrate a LiDAR (config to support Hesai and Velodyne hardware) with a camera (works for both monocular and stereo). The package finds a rotation and translation that transform all the points in the LiDAR frame to the (monocular) camera frame. Please see Usage for a video tutorial. The lidar_camera_calibration/pointcloud_fusion provides a script to fuse point clouds obtained from two stereo cameras. Both of which were extrinsically calibrated using a LiDAR and lidar_camera_calibration. We show the accuracy of the proposed pipeline by fusing point clouds, with near perfection, from multiple cameras kept in various positions. See Fusion using lidar_camera_calibration for results of the point cloud fusion (videos).

interactive_slam - Interactive Map Correction for 3D Graph SLAM

  •    C++

This package is built on top of the ROS ecosystem. You can start building a map with a pose graph constructed by hdl_graph_slam or a customized LeGO-LOAM, or odometry data generated by any ROS package. This package has been tested on Ubuntu 18.04 & ROS melodic or later.

point_labeler - My awesome point cloud labeling tool

  •    C++

Tool for labeling of a single point clouds or a stream of point clouds. Given the poses of a KITTI point cloud dataset, we load tiles of overlapping point clouds. Thus, multiple point clouds are labeled at once in a certain area.

SuMa - Surfel-based Mapping for 3d Laser Range Data (SuMa)

  •    C++

Mapping of 3d laser range data from a rotating laser range scanner, e.g., the Velodyne HDL-64E. For representing the map, we use surfels that enables fast rendering of the map for point-to-plane ICP and loop closure detection. J. Behley, C. Stachniss. Efficient Surfel-Based SLAM using 3D Laser Range Data in Urban Environments, Proc. of Robotics: Science and Systems (RSS), 2018.


opendlv - OpenDLV - A modern microservice-based software ecosystem for self-driving vehicles.

  •    CMake

Applications based on OpenDLV are grouped in UDP multicast sessions belonging to IPv4 address 225.0.0.X, where X is from the within the range [1,254]. All microservices belonging to the same UDP multicast group are able to communicate with each other; thus, two applications running in different UDP multicast sessions do not see each other and are completely separated. The actual UDP multicast session is selected using the commandline parameter --cid=111, where 111 would define the UDP multicast address 225.0.0.111. Microservices exchange data using the message Envelope that contains besides the actual message to send further meta information like sent and received timestamp and the point in time when the contained message was actually sampled. All messages are encoded in Google's Protobuf data format (example) that has been adjusted to preserve forwards and backwards compatibility using libcluon's native implementation of Protobuf.

hdl_graph_slam - 3D LIDAR-based Graph SLAM

  •    C++

hdl_graph_slam is an open source ROS package for real-time 3D slam using a 3D LIDAR. It is based on 3D Graph SLAM with NDT scan matching-based odometry estimation and loop detection. It also utilizes floor plane detection to generate an environmental map with a completely flat floor. We have tested this packaged mainly in indoor environments, but it can be applied to outdoor environment mapping as well. hdl_graph_slam consists of four nodelets.

hdl_localization - Real-time 3D localization using a (velodyne) 3D LIDAR

  •    C++

hdl_localization is a ROS package for real-time 3D localization using a 3D LIDAR, such as velodyne HDL32e and VLP16. This package performs Unscented Kalman Filter-based pose estimation. It first estimates the sensor pose from IMU data implemented on the LIDAR, and then performs multi-threaded NDT scan matching between a globalmap point cloud and input point clouds to correct the estimated pose. IMU-based pose prediction is optional. If you disable it, the system predicts the sensor pose with the constant velocity model without IMU information. All parameters are listed in launch/hdl_localization.launch as ros params. You can specify the initial sensor pose using "2D Pose Estimate" on rviz, or using ros params (see example launch file).

hdl_people_tracking - Real-time people tracking using a 3D LIDAR

  •    C++

hdl_people_tracking is a ROS package for real-time people tracking using a 3D LIDAR. It first performs Haselich's clustering technique to detect human candidate clusters, and then applies Kidono's person classifier to eliminate false detections. The detected clusters are tracked by using Kalman filter with a contant velocity model. If it doesn't work well, change ndt_neighbor_search_method in hdl_localization.launch to "DIRECT1". It makes the scan matching significantly fast, but a little bit unstable.

jackal_velodyne - Simulate Jackal with Velodyne VLP-16 or HDL-32E in Gazebo

  •    C++

You can use the following commands to download and compile the package. It's recommended that upgrade your Gazebo to the latest version, which has great performance improvements.

Stevens-VLP16-Dataset - This dataset is captured using a Velodyne VLP-16, which is mounted on an UGV - Clearpath Jackal, on Stevens Institute of Technology campus

  •    

This dataset is captured using a Velodyne VLP-16, which is mounted on an UGV - Clearpath Jackal, on Stevens Institute of Technology campus. The VLP-16 rotation rate is set to 10Hz. This data-set features over 20K scans and many loop-closures. The TF transform in the bags is provided by LeGO-LOAM (without enabling the loop-cloure function, pure lidar odometry). The whole mapping process is also recorded in videos.
