Generic Document Scanner | Flutter Document Scanner

Introduction​

The Scanbot SDK provides the ability to detect various types of documents in an image, crop them and recognize data fields via the Generic Document Recognizer.

Currently, the Generic Document Recognizer supports the following types of documents:

  • German ID Card
  • German Passport
  • German Driver's License
  • German Residence Permit

The Generic Document Recognizer is based on the OCR feature and thus requires the proper installation of the corresponding OCR language files (e.g. for English please add the file eng.traineddata). For more details on how to set up the OCR language files please refer to the OCR section.

Example Integration​

The Generic Document Scanner is available as a ready-to-use UI (RTU-UI) component. To see it in action, explore our example apps:

As a result of scanning, the user gets the GenericDocumentResults object, if the result of the scanning was successful. GenericDocument is a hierarchically structured type that contains the document's GenericDocumentNormalizedType, eventually a list of child documents, total recognition confidence, and a list of the document's fields. Each field is represented by the Field class, holding the field's type, a cropped image of the field, the recognized text and the field's recognition confidence.
