MotoReID A deep learning pipeline for **MotoGP team detection, tracking, and re-identification** from race broadcast footage. This system combines **YOLOv8** for robust object detection with **DINOv3** (Vision Transformer) embeddings for semantic team classification. It addresses specific challenges in high-speed sports computer vision: persistent identity tracking across extreme occlusions, rapid camera cuts, and motion blur. This project is in active development.

Model Overview

This repository contains trained model weights for the MotoReID project.

Included Weights

File Description Size
motogp_yolov8m_detector.pt Fine-tuned YOLOv8m for MotoGP prototype (bike) detection ~50MB
dinov3_team_classifier.pkl Logistic Regression classifier trained on DINOv3 embeddings ~35KB

Pipeline Architecture 

Video Frame → YOLOv8 Detector → Crop → DINOv3 Feature Extraction → Team Classifier → Re-ID Tracking
  1. Detection: YOLOv8m (fine-tuned) localizes motorcycles in each frame
  2. Feature Extraction: DINOv3 ViT-S/16 extracts dense semantic features from detected regions
  3. Classification: Logistic Regression head predicts team identity from DINO embeddings
  4. Re-ID & Tracking: ByteTrack + Cosine Similarity Memory Bank for persistent tracking

Supported Teams (2025 Season)

Manufacturer Teams
Ducati Lenovo Team, Gresini Racing, VR46 Racing
Aprilia Factory Racing, Trackhouse Racing
KTM Factory Racing, Tech3
Honda Repsol HRC, LCR Honda
Yamaha Monster Energy, Prima Pramac
