FR Health Card OCR PHP
The PHP 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
<?php
use Mindee\Client;
use Mindee\Product\Fr\HealthCard\HealthCardV1;
// Init a new client
$mindeeClient = new Client("my-api-key");
// Load a file from disk
$inputSource = $mindeeClient->sourceFromPath("/path/to/the/file.ext");
// Parse the file asynchronously
$apiResponse = $mindeeClient->enqueueAndParse(HealthCardV1::class, $inputSource);
echo $apiResponse->document;
Output (RST):

Document

:Mindee ID: 9ee2733d-933a-4dcd-a73a-a31395e3b288

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 (
float|string
): corresponds to the field value. Can benull
if no value was extracted. - confidence (
float
): the confidence score of the field prediction. - boundingBox (
[Point, Point, Point, Point]
): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document. - polygon (
Point[]
): contains the relative vertices coordinates (Point
) of a polygon containing the field in the image. - pageId (
integer
): the ID of the page, alwaysnull
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 __toString
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:
- dateObject (
date
): an accessible representation of the value as a php object. Can benull
.
StringField
The text field StringField
implements the following:
- value (
string
): represents the value of the field as a string. - rawValue (
string
): the value of the string as it appears on the document.
Attributes
The following fields are extracted for Health Card V1:
Given Name(s)
givenNames : The given names of the card holder.
foreach ($result->document->inference->prediction->givenNames as $givenNamesElem)
{
echo $givenNamesElem->value;
}
Issuance Date
issuanceDate : The date when the carte vitale document was issued.
echo $result->document->inference->prediction->issuanceDate->value;
Social Security Number
socialSecurity : The social security number of the card holder.
echo $result->document->inference->prediction->socialSecurity->value;
Surname
surname : The surname of the card holder.
echo $result->document->inference->prediction->surname->value;
