Object Detection with Jetson Nano

Hello, I’m trying to do image processing and object detection from Jetson Nano. For example, I want to detect the letters A, B, C, D, F. How can I do this? Is there a study on this subject or a resource you can recommend?

I’m moving this issue to Jetson Nano category for resolution.

Hi,

We do have an example for scene text recognition.
Does it meet your requirement?

Thanks.

Hi,
I cloned the file you sent and tried to install it, but it gives a lot of errors, the libraries are not installed.

Hi,

Which JetPack do you use?
It seems that the repository is built with JetPack 4.6

Thanks.

Hi,

We have tested the repository on Jetson+JetPack4.6.
It can work with some updates. Please find the details below:

1. Prerequisites

$ sudo apt-get install gfortran libopenblas-dev liblapack-dev
$ sudo pip3 install scikit-build

2. Cloning the repo

$ git clone https://github.com/NVIDIA-AI-IOT/scene-text-recognition.git
$ cd scene-text-recognition/
$ git submodule update --init --recursive

scene.patch (274 Bytes)

$ mv {scene.patch} .
$ git apply scene.patch

easyocr.patch (956 Bytes)

$ cd EasyOCR/
$ mv {easyocr.patch} .
$ git apply easyocr.patch

3. Install pytorch, torchvision
