A Multi-Vehicle Dataset with Camera, LiDAR, and Radar Sensors and Scanned 3D Models for Custom Auto-Annotation using RTK-GNSS

The paper introduces a multi-vehicle dataset that includes camera, LiDAR, and radar sensor data along with scanned 3D models of all vehicles. Each vehicle’s pose and continuous kinematics are provided via RTK‑GNSS, enabling precise knowledge of the dynamic surroundings at any time. The dataset supports single‑ and multi‑object recordings with seven target vehicles, allowing evaluation of measurement effects such as occlusion and reflections thanks to known vehicle surface normals.

Smartphone-Based Method for Automated Speed Enforcement

The paper presents a smartphone-based system that uses computer vision to automatically estimate vehicle speed and identify vehicles by license plate, make/model, and color. Experiments on a Brazilian dataset and real-world recordings in Austin, Texas show moderate recognition rates: 46% for license plates, 60.8% for color, 48.6% for make, and 16.89% for make/model. The study also discusses legal, technological, and practical considerations for deploying such smartphone recordings in traffic enforcement.
