Costa Rica license plate generator for computer vision

Features

  • Plate formats: car, motorcycle, trucks, taxi, disabled drivers.
  • Perspective rotations, size and random backgrounds.
  • Annotations with character bounding boxes (class, cx, cy, w, h)
  • configuration.cfg and templates.json files for customization.

Examples

[Pending]

Getting Started

Prerequisites

  • Python >= 3.6.0
  • Modules on requirements.txt pip3 install -r requirements.txt

Running sample code

  1. Add some images to ./backgrounds directory, these will work as random backgrounds for the plates. SUN Database is recommended.
