FR Carte Vitale OCR .NET
The .NET OCR SDK supports the Carte Vitale API.
Using the sample below, we are going to illustrate how to extract the data that we want using the OCR SDK.
Quick-Start
using Mindee;
using Mindee.Input;
using Mindee.Product.Fr.CarteVitale;
string apiKey = "my-api-key";
string filePath = "/path/to/the/file.ext";
// Construct a new client
MindeeClient mindeeClient = new MindeeClient(apiKey);
// Load an input source as a path string
// Other input types can be used, as mentioned in the docs
var inputSource = new LocalInputSource(filePath);
// Call the API and parse the input
var response = await mindeeClient
.ParseAsync<CarteVitaleV1>(inputSource);
// Print a summary of all the predictions
System.Console.WriteLine(response.Document.ToString());
// Print only the document-level predictions
// System.Console.WriteLine(response.Document.Inference.Prediction.ToString());
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:
- Confidence (
double?
): the confidence score of the field prediction. - BoundingBox (
BoundingBox
): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document. - Polygon (
Polygon
): contains the relative vertices coordinates (Polygon
extendsList<Point>
) of a polygon containing the field in the image. - PageId (
int?
): the ID of the page, alwaysnull
when at document-level.
Note: A
Point
simply refers to a List ofdouble
.
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.
StringField
The text field StringField
extends BaseField
, but also implements:
- Value (
string
): corresponds to the field value. - RawValue (
string
): corresponds to the raw value as it appears on the document.
DateField
The date field DateField
extends StringField
, but also implements:
- DateObject (
DateTime?
): an accessible representation of the value as a C# object. Can benull
.
