Python | Using PIL ImageGrab and PyTesseract

ImageGrab and PyTesseract

ImageGrab is a Python module that helps to capture the contents of the screen. PyTesseract is an Optical Character Recognition(OCR) tool for Python. Together they can be used to read the contents of a section of the screen. Installation -

Pillow (a newer version of PIL)

pip install Pillow

PyTesseract

pip install pytesseract

Apart from this, a tesseract executable needs to be installed.

Implementation of code

The following functions were primarily used in the code -

pytesseract.image_to_string(image, lang=**language**) - Takes the image and searches for words of the language in their text. cv2.cvtColor(image, **colour conversion**) - Used to make the image monochrome(using cv2.COLOR_BGR2GRAY). ImageGrab.grab(bbox=**Coordinates of the area of the screen to be captured**) - Used to repeatedly(using a loop) capture a specific part of the screen.

The objectives of the code are:

1. To use a loop to repeatedly capture a part of the screen.
2. To convert the captured image into grayscale.
3. Use PyTesseract to read the text in it.
