mrs_laser_map - Local Multiresolution Grids for Efficient 3D Laser Mapping and Localization

mrs_laser_map is a mapping system for mobile robots using laser range sensors. It provides efficient local mapping for obstacle perception, and allocentric mapping for autonomous navigation. It has been successfully used on different robotic platforms, such as micro aerial vehicles and ground robots, in different research projects and robotic competitions.

Overview

The repository contains the following ROS packages:

• mrs_laser_maps: map data structure and surfel-based registration
• mrs_laser_mapping: ROS nodes for local and allocentric mapping
• config_server: parameter server
• parameter_tuner: rqt plugin for config server
• mod_laser_filters: laser filters for preprocessing
• cloud_compression: modified pcl cloud_compression

Dependencies

• Ubuntu 14.04

• ROS Indigo:

sudo apt-get install ros-indigo-desktop-full

• g2o:

sudo apt-get install ros-indigo-libg2o

Make sure you have the latest libg2o ROS package, previous versions were compiled without optimization.
