RoadTrack: Real-Time Distant Parking Detection via Visual Geometric Projection and Velocity Estimation

📖 Overview

This project provides the first publicly available distant highway abnormal parking event dataset and baseline implementation. The dataset contains 1,000 video sequences, including 200 abnormal parking event videos and 800 normal traffic videos, providing a reliable training foundation and performance evaluation benchmark for highway abnormal event detection research.

🚀 Key Contributions

Highway Abnormal Parking Event Dataset

• Dataset Scale: 1,000 video sequences
• Data Distribution: 200 abnormal event videos + 800 normal traffic videos
• Annotation Quality: Provides detailed object detection and tracking annotations
• Research Value: Provides standardized evaluation benchmarks for subsequent research

🎬 Visualization

The following GIF animations demonstrate the detection process of vehicles transitioning from motion to stationary states at long distances. Green bounding boxes indicate moving vehicles, while red bounding boxes highlight stationary (parked) vehicles that are detected as abnormal parking events.

Event 3	Event 4

• 🚗 Green Boxes: Moving vehicles being tracked
• 🚨 Red Boxes: Stationary vehicles detected as abnormal parking events
• 📏 Long-distance Detection: Effective detection capability beyond 100 meters
• 🎯 Real-time Tracking: Continuous monitoring of vehicle status changes
