A ROS package that extracts line segments from LaserScan messages using a configurable split-and-merge algorithm with weighted line fitting.
Laser Line Extraction is a ROS package that processes laser scanner data to extract line segments from LaserScan messages. It uses a split-and-merge algorithm combined with weighted line fitting to identify geometric structures in environments, such as walls or corridors, from point cloud data. This helps robots understand their surroundings for tasks like mapping and navigation.
Robotics researchers, developers, and students working with ROS who need to extract geometric features from laser scanner data for applications like SLAM, environment modeling, or autonomous navigation.
Developers choose Laser Line Extraction for its robust, configurable algorithm that provides accurate line segments with covariance matrices, seamless ROS integration, and practical visualization tools, making it a trusted solution in academic and research robotics projects.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses a split-and-merge algorithm combined with weighted line fitting by Pfister et al. to accurately extract lines with covariance matrices for uncertainty estimation, as detailed in the README references.
Offers extensive tuning parameters like min_line_length, max_line_gap, and outlier_dist, allowing adaptation to various environments, as shown in the Parameters section of the README.
Publishes custom LineSegment messages and optional visualization markers for rviz, making it easy to integrate into existing ROS workflows, as described in the Topics and Messages sections.
Designed to process LaserScan messages efficiently, supporting real-time robotics applications like navigation and mapping, as highlighted in the Key Features.
Requires manual adjustment of numerous parameters (e.g., least_sq_thresholds, outlier_dist) for different environments, which can be time-consuming and error-prone, as noted in the Usage section.
Only handles 2D LaserScan messages, with no support for 3D point clouds or other sensor types, restricting its use to flat-plane geometric extraction.
Heavily reliant on ROS for message handling and visualization, making it unsuitable for non-ROS projects or those transitioning to newer frameworks like ROS 2 without modification.
