Number Plate Datasets

Dataset of license plate photos for computer vision. Some research groups provide clean and annotated datasets. However most dataset are rather small. Those dataset may be used by any object detection frameworks like YOLO or SSD if the bounding boxes are provided. However some work is necessary to reformat the dataset.

Holistic Recognition of Low Quality License Plates by CNN using Track Annotated Data

Datasets of number plate images. It can be used to train machine learning algorithms. Some of those datasets may contain restrictions. Please see links for details.


Plate Recognizer Proprietary Dataset

We spend all day and night looking at license plates.  We have permission from some of our partners to share images upon request.  Contact us for more info.

UCSD Car Dataset

About 10 hours of recorded video of cars entering the UCSD campus from the Gilman entrance during various times of day. Still frames taken from video feeds, hand-labeled with make and model information, license plate locations, and license plate texts. Frame by frame snapshots of the license plates of 878 cars. Still images of 291 cars in parking lots taken with a digital camera. Files are password protected.



900 of cars with gray LP; 300 of cars with red LP; 300 of motorcycles with gray LP. The dataset is released for academic research only, and is free to researchers from educational or research institutes for non-commercial purposes.


500 Images of the Rear View

License Plate Detection, Recognition and Automated Storage. Has around 500 images of the rear views.


License Plates from California

Vanity California license plates from 2015 and 2016.


South America License Plates

Dataset of South America Mercosur license plates with iamges and labels.


CCPD: Chinese City Parking Dataset

Open-source dataset for license plate detection and recognition, described in 《Towards End-to-End License Plate Detection and Recognition: A Large Dataset and Baseline》. This dataset is open-source under MIT license. More details about this dataset are avialable at our ECCV 2018 paper (also available in this github) 《Towards End-to-End License Plate Detection and Recognition: A Large Dataset and Baseline》.
