- Refactor Output Structure.
- Support Thai Driving License (Beta) สามารถสกัดข้อมูลจากภาพถ่ายใบขับขี่ได้บางรูปแบบ เนื่องจาก กรมทางขนส่งทางบก มีรูปแบบบัตรหลากหลายรูปแบบ และแต่ละรูปแบบมีตำแหน่งข้อมูลที่แตกต่างกัน จึงทำให้ประสิทธิภาพต่ำ

Usage
# With build-in Config Options.
import ThaiPersonalCardExtract as card
reader = card.PersonalCard(
lang=card.THAI,
provider=card.DEFAULT,
tesseract_cmd="D:/Program Files/Tesseract-OCR/tesseract",
save_extract_result=True,
path_to_save="D:/dev/ThaiPersonalCardExtract/examples/extract")
result = reader.extractInfo('examples/card.jpg')
print(result)
# With free-style ตัวอย่างการเรียกใช้งานคลาส PersonalCard เพื่อสกัดข้อมูลบัตรประจำตัวประชาชน
from ThaiPersonalCardExtract import PersonalCard
reader = PersonalCard(lang="mix", tesseract_cmd="D:/Program Files/Tesseract-OCR/tesseract") # for windows need to pass tesseract_cmd parameter to setup your tesseract command path.
result = reader.extractInfo('examples/card.jpg')
print(result)
# With free-style ตัวอย่างการเรียกใช้งานคลาส DrivingLicense เพื่อสกัดข้อมูลใบอนุญาตขับขี่
from ThaiPersonalCardExtract import DrivingLicense
reader = DrivingLicense(lang="mix", tesseract_cmd="D:/Program Files/Tesseract-OCR/tesseract") # for windows need to pass tesseract_cmd parameter to setup your tesseract command path.
result = reader.extractInfo('examples/card.jpg')
print(result)
# With free-style ตัวอย่างการเรียกใช้งานคลาส ThaiGovernmentLottery เพื่อสกัดข้อมูลลอตเตอร์รี่
from ThaiPersonalCardExtract import ThaiGovernmentLottery
reader = ThaiGovernmentLottery(save_extract_result=True, path_to_save="D:/dev/ThaiPersonalCardExtract/examples/extract/thai_government_lottery") # for windows need to pass tesseract_cmd parameter to setup your tesseract command path.
result = reader.extractInfo("../examples/card7.jpg")
