TrafficLab 3D: Digital-twin with just Mp4 and Google Maps
I built an open-source traffic digital twin tool that works from just:
- CCTV footage
- Google Maps imagery
Project:
https://github.com/duy-phamduc68/TrafficLab-3D
It includes:
- staged camera calibration
- object detection/tracking
- speed + orientation estimation
- synchronized CCTV + satellite visualization with 3D/floor boxes
Still has a lot of limitations (planar assumptions, occlusion problems, manual calibration workload), but I wanted to release it openly anyway and iterate from feedback.
