Isaac ROS Mapping And Localization

Overview

Isaac ROS Mapping And Localization contains a list of ROS 2 packages for mapping and localization.

• Isaac ROS Visual Global Localization provides a robust and accurate visual global localization solution as a ROS 2 package for robots. Built on the cuVGL library, this package uses stereo cameras to estimate a device’s or robot’s position in an environment without prior knowledge of its location.

• Isaac Mapping ROS includes the core implementations of cuVGL and tools for converting rosbags to cuVGL format.

• Isaac ROS Occupancy Grid Localizer provides global localization to an occupancy grid map using lidar scans.

• Isaac ROS Pointcloud Utils provides utilities for converting pointcloud messages to Flatscan messages.

• Isaac ROS Visual Mapping a ROS2 wrapper package for the visual mapping library to expose the built libraries and headers to ROS 2 ecosystem.

To learn more about cuVGL, refer to the Visual Global Localization documentation.

System Requirements

For Visual Global Localization, please see the Camera System Requirements.

Supported Platforms

This package is designed and tested to be compatible with ROS 2 Jazzy running on Jetson or an x86_64 system with an NVIDIA GPU.

Platform	Hardware	Software	Storage	Notes
Jetson	Jetson Thor	JetPack 7.0	128+ GB NVMe SSD	For best performance, ensure that power settings are configured appropriately.
x86_64	Ampere or higher NVIDIA GPU Architecture with 8 GB RAM or higher	Ubuntu 24.04	32+ GB disk space available	CUDA 13.0+ NVIDIA Driver 580+

Isaac ROS Environment

To simplify development, we strongly recommend leveraging the Isaac ROS CLI by following these steps. This streamlines your development environment setup with the correct versions of dependencies on both Jetson and x86_64 platforms.

Note

All Isaac ROS Quickstarts, tutorials, and examples have been designed with the Isaac ROS CLI-managed environment as a prerequisite.
