Fast and optimized LiDAR odometry and mapping for real-time indoor/outdoor robot localization, achieving up to 3x speedup over prior methods.
FLOAM is an optimized LiDAR odometry and mapping system that enables robots to localize themselves and build maps of their environment in real-time using 3D LiDAR data. It improves upon existing LOAM algorithms by reducing computational cost by up to 3x while maintaining high localization accuracy for both indoor and outdoor applications.
Robotics researchers and engineers working on autonomous systems that require real-time localization and mapping, particularly those using LiDAR sensors on resource-constrained platforms.
Developers choose FLOAM for its significantly faster processing speed compared to A-LOAM and LOAM while maintaining comparable or better accuracy, making it ideal for real-time robotic applications where computational efficiency is critical.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Processes LiDAR frames up to 3x faster than A-LOAM, reducing average time from 151ms to 59ms on KITTI datasets, enabling real-time operation on standard CPUs.
Shows lower localization errors on KITTI sequences, e.g., improving from 3.93% to 1.25% on sequence 02, maintaining or enhancing precision over benchmarks.
Provides simultaneous odometry and mapping for indoor and outdoor environments without specialized hardware, as demonstrated in demo videos.
Configurable for various LiDAR sensors like Velodyne VLP-16 and HDL-32 via adjustable scan lines in launch files, offering flexibility.
Fully integrated with ROS Noetic, simplifying deployment with standard launch files and node structures for robotic systems.
Tightly coupled with ROS Noetic on Ubuntu 20.04, lacking official support for ROS 2 or newer distributions, which may hinder future upgrades and compatibility.
Requires manual installation of dependencies like Ceres Solver and PCL, along with specific ROS packages, making initial setup time-consuming and prone to errors.
Focuses on core odometry and mapping without built-in loop closure or advanced SLAM features like semantic labeling, restricting use in complex, dynamic environments.
README provides basic setup instructions but lacks detailed tutorials for parameter tuning, custom sensor integration, or troubleshooting, requiring reliance on community or source code.
