CCPD paper: Towards End-to-End License Plate Detection and Recognition: A Large Dataset and Baseline

To download CCPD dataset...

• 2019 and 2020 Blue Plate and Renewable Energy Green Plate: https://github.com/detectRecog/CCPD
• 2021 Yellow Plate: https://github.com/xiaosongshine/CCPD_Plus

Prerequisite:

pip install opencv-python

Just run bbox.py or ccpd2yolotxt.py. Don't forget to replace the default CCPD directory with yours.

Format:

• CCPD filename format:

  面积比-斜度-左上右下坐标-四个角坐标（右下角开始顺时针）-车牌-亮度-模糊度

• YOLO txt format:

  0 中心点（归一化宽） 中心点（归一化长） 框宽度（归一化） 框长度（归一化）

Issue:

• It is not easy for opencv to draw Chinese characters on a picture. You could replace Chinese characters with pinyin if needed. PR is welcomed.
