@kyoryuuu hello! It sounds like you're facing an issue with detecting large targets using YOLOv8-obb. Here are a couple of suggestions that might help improve the detection accuracy for large objects:
Here's an example of how you might adjust your training command: yolo obb train data=your_dataset.yaml model=yolov8n-obb.pt epochs=100 imgsz=1280 autoanchor=true These adjustments should help the model better learn and detect large-scale objects. Let us know how it goes! 🚀 |

Question
I tried to train yolov8-obb with a dataset that has 2500 images with both large and small targets in the dataset. But when I was trying to detect a 30,0005600 target in an image with a resolution of 35,00015,000 the target was detected as small ones. How can I fix it?
