Multi Receipts Detector

Multi Receipts Detector

The PHP SDK supports the Mindee V1 Multi Receipts Detector API.

Product Specifications

Specification	Details
Endpoint Name	multi_receipts_detector
Recommended Version	v1.1
Supports Polling/Webhooks	❌ No
Support Synchronous HTTP Calls	✔️ Yes
Geography	🌐 Global

Quick-Start

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

Sample Code

<?php

use Mindee\Client;
use Mindee\Product\MultiReceiptsDetector\MultiReceiptsDetectorV1;

// 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
$apiResponse = $mindeeClient->parse(MultiReceiptsDetectorV1::class, $inputSource);

echo $apiResponse->document;

Sample 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 (float|string): corresponds to the field value. Can be null 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, always null when at document-level.

• reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

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.

PositionField

The position field PositionField does not implement all the basic BaseField attributes, only boundingBox, polygon and pageId. On top of these, it has access to:

• rectangle ([Point, Point, Point, Point]): a Polygon with four points that may be oriented (even beyond canvas).

• quadrangle ([Point, Point, Point, Point]): a free polygon made up of four points.

Attributes

The following fields are extracted for Multi Receipts Detector V1:

List of Receipts

receipts : Positions of the receipts on the document.

foreach ($result->document->inference->prediction->receipts as $receiptsElem)
{
    echo $receiptsElem->polygon;
    echo $receiptsElem->quadrangle->getCoordinates();
    echo $receiptsElem->rectangle->getCoordinates();
    echo $receiptsElem->boundingBox->getCoordinates();
}
