How to import YOLO OBB data into Labelstudio?

Label Studio Support
1

My objective is to import YOLO OBB data to check them and eventually correct them with labelstudio.

I tried the tutorial approach here but it does not work with my YOLO OBB data.

Have some tips to make it work to import YOLO OBB data?

Version of labelstudio : Label Studio version: 1.14.0.post0
Version of label-studio-converter: 1.0.7

Hello, right now LS doesn’t support YOLO OBB import in a native way.

  1. The main entry point for simple yolo import is here:
    label-studio-sdk/src/label_studio_sdk/converter/imports/yolo.py at master · HumanSignal/label-studio-sdk · GitHub
    (label-studio-converter was moved to LS SDK).

  2. However, we have this function to convert YOLO ML predictions to Label Studio:
    label-studio-sdk/src/label_studio_sdk/converter/utils.py at master · HumanSignal/label-studio-sdk · GitHub

  3. It’s used in Label Studio ML Backend for YOLO:
    label-studio-ml-backend/label_studio_ml/examples/yolo/control_models/rectangle_labels_obb.py at master · HumanSignal/label-studio-ml-backend · GitHub

So, you can try to combine SDK Converter from (1) and function from (2) to write your converter from YOLO OBB to Label Studio RectangleLabels with rotation.

Thanks you.

I’ll code one adaptation to import YOLO OBB.

I made the code and tested it.
It works fine.

See the branch
It works like :

python main.py import yolo_obb -i path_to_my_data -o path_to_my_output/output.json --image-root-url "/data/local-files/?d=my_datasets/images"

I did not add test function. It is in the agenda.

However, on which branch should I make the PR?
I did not see a develop branch.
