NanoOWL vs PeopleNet

I am undertaking a multi-company project to create a UAV prototype for surveillance and security of a restricted area and visual inspection of telecommunications infrastructures. My role in the project is to develop the AI component for intrusion detection and the visual analysis of infrastructures.

I decided to use your NVIDIA Jetson Orin Nano Developer Kit. I was studying/researching possible intrusion detection algorithms when I discovered that you have NanoOWL and PeopleNet. However, I wasn’t sure of the differences between them. Can anyone explain the differences between the two? How could I then train the algorithms? Do you also have software to adapt the code to my project/objectives?

Hello,

Welcome to the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,
Tom

My question is regarding the differences between NanoOWL and PeopleNet. Even so, should be moved to Jetson Category?

I don’t know of a better location for your topic. The Jetson folks will know for sure.

Hi,

PeopleNet is a pure detection model and can be trained with our TAO toolkit.

NanoOWL is a Vision Transformer (ViT) model which is optimized from an opensource model on huggingface.

In short, PeopleNet uses the predefined labels but NanoOWL’s output is runtime generated.

Thanks.

So for my case I should use the PeopleNet, right?

@tiagoveracruzcm ,

Thanks for reaching out.

PeopleNet is a model that is specialized in detecting people. If you need to detect people only, it is likely the better choice.

NanoOWL is an “Open-Vocabulary” object detection model, that detects objects based on generic prompts like (“a chair”, “a dog”, “a hat”, etc.). This may be a good starting point if you don’t have a model for your specialized task, or have multiple classes of interest.

Hope this helps.

Best,
John

Thank you for your help.

I will use PeopleNet for people detection.

I still have 2 more questions:

  • Does run in Jetson Orin Nano? For a flight of 30 minutes and sending the images for a outside user…
  • Could I use the NanoOwl for infrastructure inspection? Can detect flaws or it isn’t prepared for that?
