License Plate Detection

Install

pip install license_plate_detection

How to use

Download the dataset

Download the dataset from https://github.com/detectRecog/CCPD and put all of that into a directory. There is a ./exp/license_ds.csv file contains only samples of ccpd_base directory (there are few other of ccpd_* for other weather conditions) which is for faster data loading in fastai. For simplicity, I only used ccpd_base.

Experimenting

• There is a notebook named /exps/faster_rcnn.ipynb that illustrates a whole training neural workflow from loading dataset to inference

TODO

• Model haven’t been well trained, there must be some wrong implemtations
• Improve NMS operation, the current stage of region refinement of RPN is lack of NMS because the pure NMS is slow which may affects the speed of training
• Add OCR feature for detecting the license plate number of each predictions
• Add RPN config for easier customization
