Library for extract infomation from thai personal identity card. imprement from easyocr and tesseract

New Feature v1.3.5 🎁

  • Support Base64 input parameter for image object for all class. (14 Sep. 2021)
  • Support Thai identity card laser code extract. (02 Sep. 2021)
  • Fix bug dataset folder not import thai_government_lottery resource. (23 Aug. 2021) #1
  • Increase performance.
  • Support Thai Government Lottery สกัดข้อมูลจากลอตเตอร์รี่ ใช้ได้ดีกับรูปภาพที่ได้จากเครื่องแสกน (16 Aug. 2021)
  • Refactor Output Structure.
  • Support Thai Driving License (Beta) สามารถสกัดข้อมูลจากภาพถ่ายใบขับขี่ได้บางรูปแบบ เนื่องจาก กรมทางขนส่งทางบก มีรูปแบบบัตรหลากหลายรูปแบบ และแต่ละรูปแบบมีตำแหน่งข้อมูลที่แตกต่างกัน จึงทำให้ประสิทธิภาพต่ำ

Example for new feature.

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.

# สำหรับตรวจจับภาพด้านหน้าบัตร
result = reader.extract_front_info("../examples/card1.jpg")
print(result)

# หรือหากต้องการส่งไฟล์ภาพเป็น ข้อมูลแบบเข้ารหัส base64 สามารถทำได้ดังนี้ 
# สามารถส่งข้อมูลแบบ base64 แทนการส่งที่อยู่ไฟล์แบบเดิมได้ในทุก class 
result = reader.extract_front_info("/9j/4AAQSkZJRgABAQEAeAB4AA....")
print(result)

# และด้านหลังบัตร
result = reader.extract_back_info("../examples/card5.jpg")
print(result)

Recommend ⚠

  • Image quality lowest should be 600x350
  • Images with minimal reflections should be used. for good results
  • Identity Card should be size in the image about 75%, if the image doesn't cropped that to be left only Identity Card area.
  • For faster, please resize image and usage CUDA GPU.

Usage

# With build-in Config Options. For extractInfo function please use  <= v1.3.3 

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 For extractInfo function please use  <= v1.3.3 

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")
print(result)

Output will be in list format, each item represents result of library can extract, respectively. type of namedtuple ผลลัพธ์ที่ได้จะเป็นประเภท namedtuple สามารถศึกษาเพิ่มเติมเพื่อใช้งานได้จากที่นี่ คลิก

 สามารถเข้าถึงตัวแปรได้ตามรูปแบบนี้
 print(result.LotteryNumber)
 print(result.LessonNumber)
 print(result.SetNumber)
 print(result.Year)

For set lang attribute to tha For extractInfo function please use <= v1.3.3

from ThaiPersonalCardExtract import PersonalCard
reader = PersonalCard(lang="tha", 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)

Output will be in list format, each item represents result of library can extract, respectively.

{
   "Identification_Number": "9999999999999",
   "FullNameTH": "นาย อายุมฺมุราเสะ",
   "PrefixTH": "นาย",
   "NameTH": "อายุมฺมุราเสะ",
