The Java OCR SDK supports the Delivery note API.

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

Quick-Start

import com.mindee.MindeeClient;
import com.mindee.input.LocalInputSource;
import com.mindee.parsing.common.AsyncPredictResponse;
import com.mindee.product.deliverynote.DeliveryNoteV1;
import java.io.File;
import java.io.IOException;

public class SimpleMindeeClient {

  public static void main(String[] args) throws IOException, InterruptedException {
    String apiKey = "my-api-key";
    String filePath = "/path/to/the/file.ext";

    // Init a new client
    MindeeClient mindeeClient = new MindeeClient(apiKey);

    // Load a file from disk
    LocalInputSource inputSource = new LocalInputSource(new File(filePath));

    // Parse the file asynchronously
    AsyncPredictResponse<DeliveryNoteV1> response = mindeeClient.enqueueAndParse(
        DeliveryNoteV1.class,
        inputSource
    );

    // Print a summary of the response
    System.out.println(response.toString());

    // Print a summary of the predictions
//  System.out.println(response.getDocumentObj().toString());

    // Print the document-level predictions
//    System.out.println(response.getDocumentObj().getInference().getPrediction().toString());

    // Print the page-level predictions
//    response.getDocumentObj().getInference().getPages().forEach(
//        page -> System.out.println(page.toString())
//    );
  }

}

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 (Polygon): 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 extends List<Point>) of a polygon containing the field in the image.
pageId (Integer): the ID of the page, always null when at document-level.

Note: A Point simply refers to a List of Double.

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.

Attributes

The following fields are extracted for Delivery note V1:

Customer Address

customerAddress: The Customer Address field is used to store the address of the customer receiving the goods.

System.out.println(result.getDocument().getInference().getPrediction().getCustomerAddress().value);

Customer Name

customerName: The Customer Name field is used to store the name of the customer who is receiving the goods.

System.out.println(result.getDocument().getInference().getPrediction().getCustomerName().value);

Delivery Date

deliveryDate: Delivery Date is the date when the goods are expected to be delivered to the customer.

System.out.println(result.getDocument().getInference().getPrediction().getDeliveryDate().value);

Delivery Number

deliveryNumber: Delivery Number is a unique identifier for a Global Delivery Note document.

System.out.println(result.getDocument().getInference().getPrediction().getDeliveryNumber().value);

Supplier Address

supplierAddress: The Supplier Address field is used to store the address of the supplier from whom the goods were purchased.

System.out.println(result.getDocument().getInference().getPrediction().getSupplierAddress().value);

Supplier Name

supplierName: Supplier Name field is used to capture the name of the supplier from whom the goods are being received.

System.out.println(result.getDocument().getInference().getPrediction().getSupplierName().value);

Total Amount

totalAmount: Total Amount field is the sum of all line items on the Global Delivery Note.

System.out.println(result.getDocument().getInference().getPrediction().getTotalAmount().value);
