Costa Rica license plate generator for computer vision
- 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.cfgandtemplates.jsonfiles for customization.
[Pending]
- Python >= 3.6.0
- Modules on requirements.txt
pip3 install -r requirements.txt
-
Add some images to ./backgrounds directory, these will work as random backgrounds for the plates. SUN Database is recommended.
-
Run the main file
python ./main.py -
Random plates will be generated on ./output directory
