Moon Detection Dataset for YOLOv8

This dataset was developed as part of the CubeRT-02 project, a CubeSat mission aimed at testing AI-powered vision systems in aerospace contexts. It consists of 7500+ annotated images for object detection of the Moon, optimized for use with the YOLOv8 architecture.

📸 Dataset Collection & Annotation

Initial set: ~400 web-sourced images used for theoretical model exploration.

Main dataset: 7500+ images captured over 6 months using smartphones and amateur camera devices, reflecting real-world scales, perspectives, and conditions.

Cleaning: Manual filtering of blurry, low-quality, or irrelevant images.

Annotation: Performed via Roboflow platform with bounding boxes for YOLOv8.

Augmentation: Basic augmentations applied during preparation; none used during final training due to negative effects on performance.

📁 Dataset Structure

This dataset follows the YOLOv8 format. A Python script and a YAML configuration file are included to help you easily train or test the dataset using Ultralytics' YOLOv8 implementation.
