FR Health Card OCR Ruby
The Ruby 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.
Quick-Start
require 'mindee'
# Init a new client
mindee_client = Mindee::Client.new(api_key: 'my-api-key')
# Load a file from disk
input_source = mindee_client.source_from_path('/path/to/the/file.ext')
# Parse the file
result = mindee_client.enqueue_and_parse(
input_source,
Mindee::Product::FR::HealthCard::HealthCardV1
)
# Print a full summary of the parsed data in RST format
puts result.document
# Print the document-level parsed data
# puts result.document.inference.prediction
Output (RST):

Field Types
Standard Fields
These fields are generic and used in several products.
Basic Field
Each prediction object contains a set of fields that inherit from the generic Field
class.
A typical Field
object will have the following attributes:
- value (
String
,Float
,Integer
,Boolean
): corresponds to the field value. Can benil
if no value was extracted. - confidence (Float, nil): the confidence score of the field prediction.
- bounding_box (
Mindee::Geometry::Quadrilateral
,nil
): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document. - polygon (
Mindee::Geometry::Polygon
,nil
): contains the relative vertices coordinates (Point
) of a polygon containing the field in the image. - page_id (
Integer
,nil
): the ID of the page, alwaysnil
when at document-level. - reconstructed (
Boolean
): indicates whether an object was reconstructed (not extracted as the API gave it).
Aside from the previous attributes, all basic fields have access to a to_s
method that can be used to print their value as a string.
Date Field
Aside from the basic Field
attributes, the date field DateField
also implements the following:
- date_object (
Date
): an accessible representation of the value as a JavaScript object.
String Field
The text field StringField
only has one constraint: it's value is a String
(or nil
).
Attributes
The following fields are extracted for Health Card V1:
Given Name(s)
given_names (Array<StringField>): The given names of the card holder.
for given_names_elem in result.document.inference.prediction.given_names do
puts given_names_elem.value
end
Issuance Date
issuance_date (DateField): The date when the carte vitale document was issued.
puts result.document.inference.prediction.issuance_date.value
Social Security Number
social_security (StringField): The social security number of the card holder.
puts result.document.inference.prediction.social_security.value
Surname
surname (StringField): The surname of the card holder.
