VehicleNet-RFDETR-n

Overview

VehicleNet-RFDETR-n is a multi-class vehicle detection model designed for fine-grained vehicle type recognition in real-world traffic scenes. It is fine-tuned on the UVH-26-MV Dataset, curated and released by the Indian Institute of Science (IISc), Bangalore, which captures the highly complex, dense, and heterogeneous nature of Indian road traffic.

The model recognizes 14 vehicle categories, including hatchbacks, sedans, SUVs, MUVs, two-wheelers, three-wheelers, buses, trucks, and a range of commercial vehicle types. This nano variant is optimized for low-latency inference, balancing speed and accuracy for deployment on resource-constrained hardware.

The model is fine-tuned on the RFDETRNano architecture (arXiv: 2511.09554) by Roboflow, using rfdetr version 1.6.1.
