# NVIDIA Redtail project

Autonomous visual navigation components for drones and ground vehicles using deep learning. Refer to [wiki](https://github.com/NVIDIA-Jetson/redtail/wiki) for more information on how to get started.

This project contains deep neural networks, computer vision and control code, hardware instructions and other artifacts that allow users to build a drone or a ground vehicle which can autonomously navigate through highly unstructured environments like forest trails, sidewalks, etc. Our TrailNet DNN for visual navigation is running on NVIDIA's Jetson embedded platform. Our [arXiv paper](https://arxiv.org/abs/1705.02550) describes TrailNet and other runtime modules in detail.

The project's deep neural networks (DNNs) can be trained from scratch using publicly available data. A few [pre-trained DNNs](../master/models/pretrained/) are also available as a part of this project. In case you want to train TrailNet DNN from scratch, follow the steps on [this page](../../wiki/Models).

The project also contains [Stereo DNN](../master/stereoDNN/) models and runtime which allow to estimate depth from stereo camera on NVIDIA platforms.

**IROS 2018**: we presented our work at [IROS 2018](https://www.iros2018.org/) conference as a part of [Vision-based Drones: What's Next?](https://www.seas.upenn.edu/~loiannog/workshopIROS2018uav/) workshop.

**CVPR 2018**: we presented our work at [CVPR 2018](http://cvpr2018.thecvf.com/) conference as a part of [Workshop on Autonomous Driving](http://www.wad.ai/index.html).
