LSD currently supports many features:

• support multiple LiDAR, camera, radar and INS/IMU sensors.
• support user-friendly calibration for LiDAR and camera etc.
• support software time sync, data record and playback.
• support voxel 3D-CNN based pointcloud object detection, tracking and prediction.
• support FastLIO based frontend odometry and G2O based pose graph optimization.
• support Web based interactive map correction tool(editor).
• support communication with ROS.

• Quick Demo
• Architecture
• Mapping & Localization
• Object Detection & Tracking

[2023-10-08] Better 3DMOT (GIOU, Two-stage association).

[2023-07-06] A new detection model (CenterPoint-VoxelNet) is support to run realtime (30FPS+).

Note: the CenterPoint-VoxelNet is built on libspconv and the GPU with SM80+ is required.

[2023-06-01] Web UI(JS code of preview, tviz and map editor) is uploaded.

Ubuntu20.04, Python3.8, Eigen 3.3.7, Ceres 1.14.0, Protobuf 3.8.0, NLOPT 2.4.2, G2O, OpenCV 4.5.5, PCL 1.9.1, GTSAM 4.0

NVIDIA Container Toolkit is needed to install firstly Installation.

A x86_64 docker image is provided to test.

sudo docker pull 15liangwang/lsd-cuda118 # sudo docker pull 15liangwang/auto-ipu, if you don't have GPU
sudo docker run --gpus all -it -d --net=host --privileged --shm-size=4g --name="LSD" -v /media:/root/exchange 15liangwang/lsd-cuda118
sudo docker exec -it LSD /bin/bash

LSD is NOT built on the Robot Operating System (ROS), but we provides some tools to bridge the communication with ROS.

• rosbag to pickle: convert rosbag to pickle files, then LSD can read and run.
• pickle to rosbag: a convenient tool to convert the pickle files which are recorded by LSD to rosbag.
• rosbag proxy: a tool which send the ros topic data to LSD.

LSD is released under the Apache 2.0 license.

In the development of LSD, we stand on the shoulders of the following repositories:

• lidar_align: A simple method for finding the extrinsic calibration between a 3D lidar and a 6-dof pose sensor.
• lidar_imu_calib: automatic calibration of 3D lidar and IMU extrinsics.
• OpenPCDet: OpenPCDet Toolbox for LiDAR-based 3D Object Detection.
• AB3DMOT: 3D Multi-Object Tracking: A Baseline and New Evaluation Metrics.
• FAST-LIO: A computationally efficient and robust LiDAR-inertial odometry package.
• R3LIVE: A Robust, Real-time, RGB-colored, LiDAR-Inertial-Visual tightly-coupled state Estimation and mapping package.
• FLOAM: Fast and Optimized Lidar Odometry And Mapping for indoor/outdoor localization.
• hdl_graph_slam: an open source ROS package for real-time 6DOF SLAM using a 3D LIDAR.
• hdl_localization: Real-time 3D localization using a (velodyne) 3D LIDAR.
• ORB_SLAM2: Real-Time SLAM for Monocular, Stereo and RGB-D Cameras, with Loop Detection and Relocalization Capabilities.
• scancontext: Global LiDAR descriptor for place recognition and long-term localization.
