Usage Suggestions

This section offers suggestions for using a Realsense camera with the Isaac SDK.

Using a USB 3.0 Port with a USB 3.0 Cable

The Realsense camera requires a USB3.0+ connection. USB 3.0 ports and cables can be identified by blue-color components on the inside of ports and cable connectors. The Jetson Xavier USB-C ports are USB 3.0 ports.

Testing the Realsense camera with USB-C ports has revealed stability issues that are resolved by using an unpowered USB hub. The AmazonBasics USB 3.1 Type-C to 4-Port Aluminum Hub Connector has shown to be very reliable at working with the Realsense camera.

Setting the Power Model

Running sudo nvpmodel -m 0 enables all cores, and increases the scaling minimum clock frequency. This change persists over reboot. Run sudo nvpmodel -q to display current settings. This increases proccessing power and may result in reduced frame drops and image blur, in some situations.
