Traffic Counter with Imaginary Line Crossing Detection

Objective

Counts the number of vehicles and pedestrians via CCTV when the object crosses the defined imaginary line.

Deteils

• Utilizing object detection: YOLOv5 by ultralytics for vehicle detection and localization.
• Utilizing object tracking: Deep Sort with PyTorch, PyTorch implementation from original Deep SORT.
• Detection of vehicles crossing the imaginary line using matrix calculation.
• All events will be stored to the database in realtime using API.

Keywords

object detection, object tracking, computer vision, machine learning
