tesseract-ocrHow can I integrate Tesseract OCR into a Unity project?

Integrating Tesseract OCR into a Unity project is relatively straightforward.

  1. First, you'll need to download the Tesseract OCR library from here.

  2. Then, you'll need to create a C# wrapper for Tesseract. This can be done using the Tesseract.Net library.

  3. Next, you'll need to create a script in Unity that calls the Tesseract library.

For example:

using System.IO;
using Tesseract;

public class OCRScript : MonoBehaviour {
  void Start() {
    // Create a new Tesseract Engine
    using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default)) {
      // Create an image object using the filename
      using (var img = Pix.LoadFromFile(@"./test.png")) {
        // Set the image to the engine
        using (var page = engine.Process(img)) {
          // Get the text from the engine
          var text = page.GetText();

This script will load the image test.png and output the text recognized by Tesseract using the Debug.Log function.

Finally, attach the script to a game object in the scene and run the game.

That's it! You should now have Tesseract OCR integrated into your Unity project.
