Vision with Jetson Development Boards

This serves as a documentation & reference for the various resources available for the Jetson Orin Nano, Jetson Xavier NX & Jetson Nano development board with regards to Vision and AI based projects.

The documentation/resources related to the older Jetson Nano (B01) / Jetson Xavier NX development boards would be shifted to the archive directory & the README here.

Organisation

The directory is organised as follows:

• AI_ML: AI & Machine Learning related project(s)
• cpp_proj: C++ related projects
• scripts: Installation & setup scripts. Scripts for the older Jetson Nano and Jetson Xavier NX would be shifted to archive directory inside.

Nvidia lib location

• libargus/Argus (For image processing): /usr/src/jetson_multimedia_api/argus/
• Multimedia API: /usr/src/jetson_multimedia_api/

Prerequisite

CUDA paths

Ensure that the CUDA compiler (nvcc) is added to ~/.bashrc, which could be done so via the add_cuda_path.sh script.

cd ~/cv4-jet-nano/scripts
sudo chmod +x add_cuda_path.sh
./add_cuda_path.sh

Camera

Setup (CSI Camera)

Configure the camera via the jetson-io.py script for the Jetson Orin Nano.

sudo /opt/nvidia/jetson-io/jetson-io.py

The terminal show display the menu. Select Configure Jetson 24pin CSI Connector.
