Validación manual para digitalizar documentos

The example below explains how to manually extract data from an image and present the output in a separate file. It presents activities such as Digitize Document or Present Validation Station. You can find these activities in the UiPath.IntelligentOCR.Activities package.

Nota:

This workflow is using an older version of the UiPath.IntelligentOCR.Activities package.

Steps:

1. Abre Studio y crea un nuevo Proceso llamado Principal de forma predeterminada.

   Nota:

   Make sure to add all the needed files (.json files and all the images) inside the project folder.

2. Add a Sequence container in the Workflow Designer and create the variables shown in the following table:

   Table 1. Variables to be created

   	Tipo de variable	Valor predeterminado
   Text	Cadena
   DOM	UiPath.DocumentProcessing.Contracts.Dom.Document
   Data	UiPath.DocumentProcessing.Contracts.Taxonomy.DocumentTaxonomy
   DocumentTaxonomy	UiPath.DocumentProcessing.Contracts.Taxonomy.DocumentTaxonomy
   TaxonomyJSON	Cadena
   HumanValidated	UiPath.DocumentProcessing.Contracts.Results.ExtractionResult

3. Add a Read Text File activity inside the sequence.

   • In the Properties panel, add the name of the file, in this case "taxonomy.json", in the FileName field.
   • Add the variable TaxonomyJSON in the Content field.

4. Add an Assign activity after the Read Text File activity.

   • Add the variable Data in the To field and the expression DocumentTaxonomy.Deserialize(TaxonomyJSON) in the Value field. This activity builds the taxonomy for extraction.

5. Add a Digitize Document activity after the Assign activity.

   • In the Properties panel, add the value 1 in the DegreeOfParallelism field.
   • Add the expression "Input\Invoice01.tif" in the DocumentPath field.
   • Add the variable DOM in the DocumentObjectModel field.
   • Add the variable Text in the DocumentText field.

6. Add a Google OCR engine inside the Digitize Document activity.

   • En el panel de propiedades, añade la variable Image al campo Imagen.
   • Select the check box for the ExtractWords option. This option extracts the on-screen position of all detected words.
   • Add the expression "eng" in the Language field.
   • Select the option Legacy from the Profile drop-down list.
   • Agrega el valor 2 en el campo Escala.

7. Add a Present Validation Station activity after the Digitize Document activity.

   • In the Properties panel, add the variable DOM in the DocumentObjectModel field.
   • Add the expression "Input\Invoice01.tif" in the DocumentPath field.
   • Add the variable Text in the DocumentText field.
   • Add the variable Data in the Taxonomy field.
   • Add the variable HumanValidated in the ValidatedExtractionResults field.

8. Add a For Each activity under the Present Validation Station activity.

   • In the Properties panel, select the option UiPath.DocumentProcessing.Contracts.Results.ResultsDataPoint from the TypeArgument drop-down list.
   • Add the expression HumanValidated.ResultsDocument.Fields in the Values field.

9. Add a Log Message activity inside the Body of the For Each activity.

   • Select the option Info from the Level drop-down list.
   • Agrega la expresión item.FieldName en el campo Mensaje.

10. Add a Log Message activity below the first Log Message activity.

    • Select the option Info from the Level dropdown list.
    • Agrega la expresión item.Values(0).Value.ToString en el campo Mensaje.

11. Add a Write Line activity under the Log Message activities.

    • Añade el valor "" al campo Texto.

12. Ejecuta el proceso. El robot utiliza las actividades IntelligentOCR para procesar manualmente los datos y presentar los resultados.
