The Python OCR SDK supports the Driver License API.

Using the sample below, we are going to illustrate how to extract the data that we want using the OCR SDK.
Driver License sample

Quick-Start

from mindee import Client, product, AsyncPredictResponse

# Init a new client
mindee_client = Client(api_key="my-api-key")

# Load a file from disk
input_doc = mindee_client.source_from_path("/path/to/the/file.ext")

# Load a file from disk and enqueue it.
result: AsyncPredictResponse = mindee_client.enqueue_and_parse(
    product.DriverLicenseV1,
    input_doc,
)

# Print a brief summary of the parsed data
print(result.document)

Output (RST):

Field Types

Standard Fields

These fields are generic and used in several products.

BaseField

Each prediction object contains a set of fields that inherit from the generic BaseField class.
A typical BaseField object will have the following attributes:

value (Union[float, str]): corresponds to the field value. Can be None if no value was extracted.
confidence (float): the confidence score of the field prediction.
bounding_box ([Point, Point, Point, Point]): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.
polygon (List[Point]): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.
page_id (int): the ID of the page, always None when at document-level.
reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

Note: A Point simply refers to a List of two numbers ([float, float]).

Aside from the previous attributes, all basic fields have access to a custom __str__ method that can be used to print their value as a string.

DateField

Aside from the basic BaseField attributes, the date field DateField also implements the following:

date_object (Date): an accessible representation of the value as a python object. Can be None.

StringField

The text field StringField only has one constraint: its value is an Optional[str].

Attributes

The following fields are extracted for Driver License V1:

Country Code

country_code (StringField): The alpha-3 ISO 3166 code of the country where the driver license was issued.

print(result.document.inference.prediction.country_code.value)

Date of Birth

date_of_birth (DateField): The date of birth of the driver license holder.

print(result.document.inference.prediction.date_of_birth.value)

DD Number

dd_number (StringField): The DD number of the driver license.

print(result.document.inference.prediction.dd_number.value)

Expiry Date

expiry_date (DateField): The expiry date of the driver license.

print(result.document.inference.prediction.expiry_date.value)

First Name

first_name (StringField): The first name of the driver license holder.

print(result.document.inference.prediction.first_name.value)

ID

id (StringField): The unique identifier of the driver license.

print(result.document.inference.prediction.id.value)

Issued Date

issued_date (DateField): The date when the driver license was issued.

print(result.document.inference.prediction.issued_date.value)

Issuing Authority

issuing_authority (StringField): The authority that issued the driver license.

print(result.document.inference.prediction.issuing_authority.value)

Last Name

last_name (StringField): The last name of the driver license holder.

print(result.document.inference.prediction.last_name.value)

MRZ

mrz (StringField): The Machine Readable Zone (MRZ) of the driver license.

print(result.document.inference.prediction.mrz.value)

Place of Birth

place_of_birth (StringField): The place of birth of the driver license holder.

print(result.document.inference.prediction.place_of_birth.value)

State

state (StringField): Second part of the ISO 3166-2 code, consisting of two letters indicating the US State.

print(result.document.inference.prediction.state.value)
