License-Plates-Detector-Model: Optimized for Qualcomm Devices

A YOLOv8-nano object detection model fine-tuned on the UAE licence-plate dataset (Roboflow car-plate-k6xij v26). The model detects and classifies 51 object classes: digits 0-9, letters A-Z, UAE emirate region identifiers and a plate bounding-box class for the full plate region.

This is based on the implementation of License-Plates-Detector-Model found here. This repository contains pre-exported model files optimized for Qualcomm® devices. You can use the Qualcomm® AI Hub Models library to export with custom configurations. More details on model performance across various devices, can be found here.

Qualcomm AI Hub Models uses Qualcomm AI Hub Workbench to compile, profile, and evaluate this model. Sign up to run these models on a hosted Qualcomm® device.

Getting Started

Due to licensing restrictions, we cannot distribute pre-exported model assets for this model. Use the Qualcomm® AI Hub Models Python library to compile and export the model with your own:

  • Custom weights (e.g., fine-tuned checkpoints)
  • Custom input shapes
  • Target device and runtime configurations

See our repository for License-Plates-Detector-Model on GitHub for usage instructions.
