Jetson Nano – RealSense Depth Camera

Jetson Nano + Intel RealSense Depth Camera

Getting full support for the Intel RealSense Depth Camera on the NVIDIA Jetson Nano Developer Kit is simplified by using a couple of installation scripts. Looky here:


In an earlier article, we installed an Intel RealSense Tracking Camera on the Jetson Nano along with the librealsense SDK. We’ve have used the RealSense D400 cameras a lot on the other Jetsons, now it’s time to put them to work on the Jetson Nano.

For best performance and support of the RealSense Depth Camera features, Intel recommends modifying the Linux kernel and modules.

To remind you of the different cameras available, here’s a couple of the more popular models which points out their features:

Intel® RealSenseTM Depth Camera D415

Intel® RealSenseTM Depth Camera D435/D435i 

For robotics applications, the D435 is popular due to its global shutter and wide field of view.

Software Installation

To interface with the camera,  Intel provides the open source library librealsense. On the JetsonHacksNano account on Github, there is a repository named installLibrealsense. The repository contains convenience scripts to install librealsense.

In order to use the install script, you will either need to create a swapfile to ease an out of memory issue, or modify the install script to run less jobs during the make process. In the video, we chose the swapfile route. To install the swapfile:

$ git clone
$ cd installSwapfile
$ ./
$ cd ..

You’re now ready to install librealsense.

$ git clone
$ cd installLibrealsense
$ ./

While the script has the option to compile the librealsense with CUDA support. If you want to add CUDA support to the librealsense SDK, add a -c switch to the shell script:

$ ./ -c

Kernel and Modules

For the RealSense Depth Cameras, you will find that performance is much better if you apply the patches to the kernel models. Note: If you have a D435i, the camera will not be detected without the patches.

This video covers the differences between only installing librealsense versus librealsense plus the kernel modifications. Looky here:

To install the kernel and module patches, build them, and then install first switch to the installLibrealsense directory then:

You’re now ready to install librealsense.

$ ./

This will start the patch, build and install process. On a micro SD card this will take ~ one hour, 20 minutes. Note: If you compile the kernel and modules on a USB SSD, remember to copy the new Image to the /boot directory of the SD card which you boot from.


Go to the demos and tools directory in /usr/local/bin, and checkout the realsense-viewer application and all of the different demonstrations! There are a wide variety of code samples for different uses in the librealsense SDK. When you go to program against the SDK, you’ll benefit from having a good catalog with which to work.
