Attention
As of June 30, 2025, the Isaac ROS Buildfarm for Isaac ROS 2.1 on Ubuntu 20.04 Focal is no longer supported.
Due to an isolated infrastructure event, all ROS 2 Humble Debian packages that were previously built for Ubuntu 20.04 are no longer available in the Isaac Apt Repository. All artifacts for Isaac ROS 3.0 and later are built and maintained with a more robust pipeline.
Users are encouraged to migrate to the latest version of Isaac ROS. The source code for Isaac ROS 2.1
continues to be available on the release-2.1
branches of the Isaac ROS
GitHub repositories.
The original documentation for Isaac ROS 2.1 is preserved below.
Tutorial to Run NITROS-Accelerated Graph with Argus Camera
In this tutorial, you perform H.264 encoding using an Argus-compatible camera and an isaac_ros_h264_encoder. Then you save the compressed images into a rosbag.
Follow the quickstart here up to step 6.
Inside the container, install the
isaac_ros_argus_camera
package.sudo apt-get install -y ros-humble-isaac-ros-argus-camera
Run the launch file. This launch file launches the example and records
CompressedImage
andCameraInfo
topic data into a rosbag in your current folder.ros2 launch isaac_ros_h264_encoder isaac_ros_h264_encoder_argus.launch.py
(Optional) If you want to decode and visualize the images from the rosbag, you can place the recorded rosbag into an x86 machine equipped with NVIDIA GPU, then follow steps 7 and 8 in the Quickstart section. (Change the rosbag path and input dimension accordingly in step 7):
ros2 launch isaac_ros_h264_decoder isaac_ros_h264_decoder_rosbag.launch.py rosbag_path:=<"path to your rosbag folder">
For example, the result looks like:
