The Python OCR SDK supports the Health Card API.

Using the sample below, we are going to illustrate how to extract the data that we want using the OCR SDK.
Health Card 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.fr.HealthCardV1,
    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 Health Card V1:

Given Name(s)

given_names (List[StringField]): The given names of the card holder.

for given_names_elem in result.document.inference.prediction.given_names:
    print(given_names_elem.value)

Issuance Date

issuance_date (DateField): The date when the carte vitale document was issued.

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

Social Security Number

social_security (StringField): The social security number of the card holder.

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

Surname

surname (StringField): The surname of the card holder.

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