How to Extract Text from Image-UiPath RPA

 

To extract text from an image using UiPath, you can use the OCR (Optical Character Recognition) capabilities provided by UiPath. UiPath has built-in activities for OCR that allow you to extract text from images and PDFs. Here's a step-by-step guide on how to do this:

 

Install UiPath OCR Activities: 

Ensure that you have the necessary OCR activities installed in UiPath. You can check this in the "Manage Packages" section in UiPath Studio. If you don't have the required OCR activities installed, you can install them from the UiPath Package Manager.

Create a New Project: 

Open UiPath Studio and create a new project or use an existing one where you want to perform image text extraction.

Add an Image to the Project: 

Include the image from which you want to extract text in your project by adding it to the project folder or referencing its path.

 Use the "Read PDF Text" or "Read Text" Activity: 

Drag and drop the "Read PDF Text" or "Read Text" activity (depending on your image format, as these activities can handle both images and PDFs) into your workflow.

For images, you can use the "Read Image Text" activity.

For PDFs, you can use the "Read PDF Text" activity.

Load Image: -  

  This Activities enable to load an image from the disk and save it to an image  string variable  

Configure the Activity: 

Configure the activity to specify the input image path. You can do this by clicking on the activity and providing the image file path or by using variables if the path varies.

Choose OCR Engine: 

You can select the OCR engine that best suits your needs. UiPath provides several OCR engines, including Tesseract, Google OCR, and Microsoft OCR. Each has its strengths and may perform differently based on the image quality and content.

Output Variable: 

Configure an output variable to store the extracted text. This is where the text extracted from the image will be stored for further processing.

Handle Errors: 

It's a good practice to add error handling to deal with scenarios where text extraction may fail. You can use Try-Catch activities to handle exceptions that may occur during the OCR process.

Process the Extracted Text:

You can then use the extracted text as needed in your automation, whether it's for data entry, validation, or any other purpose.

Save the Extracted Text: 

If you need to save the extracted text to a file or a database, add the necessary activities to achieve this.

Run the Workflow: 

Finally, run your workflow to extract text from the image.

Remember that the accuracy of text extraction depends on the quality of the image and the chosen OCR engine. You may need to experiment with different OCR engines and preprocessing techniques to get the best results for your specific image.
