Python OCR Tesseract, find a certain word in the image and return me the coordinates - ocr

Question

I wanted your help, I've been trying for a few months to make a code that finds a word in the image and returns the coordinates where that word is in the image.
I was trying this using OpenCV, OCR tesseract, but I was not successful, could someone here in the community help me?
I'll leave an image here as an example:

Answer 1

Here is something you can start with:
import pytesseract
from PIL import Image
pytesseract.pytesseract.tesseract_cmd = r'C:\<path-to-your-tesseract>\Tesseract-OCR\tesseract.exe'
img = Image.open("img.png")
data = pytesseract.image_to_data(img, output_type='dict')
boxes = len(data['level'])
for i in range(boxes):
if data['text'][i] != '':
print(data['left'][i], data['top'][i], data['width'][i], data['height'][i], data['text'][i])

Answer 2

I managed to find the solution and I'll post it here for you:
import pytesseract
import cv2
from pytesseract import Output
pytesseract.pytesseract.tesseract_cmd = r'C:\<path-to-your-tesseract>\Tesseract-OCR\tesseract.exe'
filepath = 'image.jpg'
image = cv2.imread(filepath, 1)
# converting image to grayscale image
gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# converting to binary image by Thresholding
# this step is necessary if you have a color image because if you skip this part
# then the tesseract will not be able to detect the text correctly and it will give an incorrect result
threshold_img = cv2.threshold(gray_image, 0, 255, cv2.THRESH_BINARY | cv2.THRESH_OTSU)[1]
# displays the image
cv2.imshow('threshold image', threshold_img)
# Holds the output window until the user presses a key
cv2.waitKey(0)
# Destroying windows present on the screen
cv2.destroyAllWindows()
# setting parameters for tesseract
custom_config = r'--oem 3 --psm 6'
# now feeding image to tesseract
details = pytesseract.image_to_data(threshold_img, output_type=Output.DICT, config=custom_config, lang='eng')
# Color
vermelho = (0, 0, 255)
#Exibe todas as chaves encontradas
print(details.keys())
print(details['text'])
# For in all found texts
for i in range(len(details['text'])):
# If it finds the text "UNIVERIDADE" it will print the coordinates, and draw a rectangle around the word
if details['text'][i] == 'UNIVERSIDADE':
print(details['text'][i])
print(f"left: {details['left'][i]}")
print(f"top: {details['top'][i]}")
print(f"width: {details['width'][i]}")
print(f"height: {details['height'][i]}")
cv2.rectangle(image, (details['left'][i], details['top'][i]), (details['left'][i]+details['width'][i], details['top'][i]+details['height'][i]), vermelho)
