Isaac ros object detection usb camera

[rlatae123]

ros2 launch isaac_ros_detectnet isaac_ros_detectnet_quickstart.launch.py

When executing the above command, is there a way to proceed through a USB camera instead of a test image?

Hi @rlatae123

you can modify the isaac_ros_detectnet_quickstart.launch.py and run instead of a rosbag file a usb_cam package.
You can install on the Isaac ROS container with:

sudo apt install ros-humble-usb-cam

When you connect the USB cam node to the isaac_ros_detectnet check the encoding output and the image resolution you want to use with your camera.

Hi @Raffaello

I disabled the rosbag part of the quickstart.launch.py file and ran it again, but rosbag is still running.

Is there a way to build only the launch part?

[Raffaello]

yes, sure.

you can build your own ROS2 package, on the ROS2 workspace following the Open Robotics guidelines

The workspace folder on your x86 machine is located on your host in

cd  ~/workspaces/isaac_ros-dev/src

Or watch the documentation on Developer Environment Setup — isaac_ros_docs documentation
