[python] Pytesseract : "TesseractNotFound Error: tesseract is not installed or it's not in your path", how do I fix this?

Step 1:

Install tesseract on your system as per the OS. Latest installers can be found at https://github.com/UB-Mannheim/tesseract/wiki

Step 2: Install the following dependency libraries using : pip install pytesseract pip install opencv-python pip install numpy

Step 3: Sample code

import cv2
import numpy as np
import pytesseract
from PIL import Image
from pytesseract import image_to_string

# Path of working folder on Disk Replace with your working folder
src_path = "C:\\Users\\<user>\\PycharmProjects\\ImageToText\\input\\"
# If you don't have tesseract executable in your PATH, include the 
following:
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract- 
OCR/tesseract'
TESSDATA_PREFIX = 'C:/Program Files (x86)/Tesseract-OCR'

def get_string(img_path):
    # Read image with opencv
    img = cv2.imread(img_path)

    # Convert to gray
    img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

    # Apply dilation and erosion to remove some noise
    kernel = np.ones((1, 1), np.uint8)
    img = cv2.dilate(img, kernel, iterations=1)
    img = cv2.erode(img, kernel, iterations=1)

    # Write image after removed noise
    cv2.imwrite(src_path + "removed_noise.png", img)

    #  Apply threshold to get image with only black and white
    #img = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 31, 2)

    # Write the image after apply opencv to do some ...
    cv2.imwrite(src_path + "thres.png", img)

    # Recognize text with tesseract for python
    result = pytesseract.image_to_string(Image.open(src_path + "thres.png"))

    # Remove template file
    #os.remove(temp)

    return result


print('--- Start recognize text from image ---')
print(get_string(src_path + "image.png") )

print("------ Done -------")
