flutter_ocr_sdk 0.0.1

A new flutter plugin project.

flutter_ocr_sdk

A wrapper for Dynamsoft OCR SDK, focusing on Passport MRZ recognition.

Try Passport MRZ Example

cd example
flutter run -d <device>

Usage

• Download the model package. Unzip model files to model/ folder, and configure assets in pubspec.yaml:

  assets:
  - model/
  - model/CharacterModel/
  

• Initialize the object and load the model path by the asset path:

  _textRecognizer = FlutterOcrSdk();
  _textRecognizer.loadModel('model/');
  

• Recognize passport MRZ by setting an image file and the template name locr. The template name is defined in model/wholeImgMRZTemplate.json:

  String ret = await _textRecognizer.recognizeByFile(image?.path, 'locr');
  

• Recognize passport MRZ by setting an image buffer (E.g. CameraImage) and the template name locr:

  CameraImage availableImage;
  String ret = await _textRecognizer.recognizeByFile(availableImage.planes[0].bytes,
            availableImage.width,
            availableImage.height,
            availableImage.planes[0].bytesPerRow,
            format, 'locr');
  

• Set the organization ID if you have a Dynamsoft account:

  await _textRecognizer.setOrganizationID('YOUR-ID');
