Print numbers from video frames to console using pytesseract

Question

This is my first ever Python program. It checks every frame of a video file with Tesseract then uses OCR to recognise numbers in that frame and prints it to the console.

import pytesseract
import os
import cv2
import openpyxl
from numpy import interp
import numpy as np

# Video URL
TEST_VID = cv2.VideoCapture("VET2.mp4")
READING, IMG = TEST_VID.read()

# Frame Number
INDEX = 0

# Colours
black = [0, 0, 0]


while READING:

    TEST_VID.set(1, INDEX)
    READING, IMG = TEST_VID.read()
    RET, FRAME = TEST_VID.read()

    # If I want to print images
    # print("new frame: ", READING)
    # if not RET:
    #     break

    # # Assign a name for the file
    # NAME = "./image_frames/frame" + str(INDEX) + ".png"

    # # Assign the print statement
    # print("Extracting frames..." + NAME)
    # cv2.imwrite(NAME, FRAME)

    pixel = FRAME[2100, 1800]

    # If a pixel is black, use these values
    if np.all(pixel == black):

        # Image coordinates [y1:y2, x1:x2]
        speed = FRAME[2775:2883, 1199:1486]
        rpm = FRAME[2948:3014, 1190:1500]
        gear = FRAME[3187:3248, 1359:1415]

    # Tesseract directory
    pytesseract.pytesseract.tesseract_cmd = (
        r"C:\Program Files\Tesseract-OCR\tesseract.exe"
    )

    # Print KPH to console
    print(
        "Speed = "
        + pytesseract.image_to_string(
            speed,
            lang="formula1",
            config="--psm 7 -c tessedit_char_whitelist=0123456789",
        )
    )
    # cv2.imshow("speed", speed)
    # cv2.waitKey(0)

    # Print RPM to console
    print(
        "RPM = "
        + pytesseract.image_to_string(
            rpm,
            lang="formula1",
            config="--psm 7 -c tessedit_char_whitelist=0123456789",
        )
    )
    # cv2.imshow("rpm", rpm)
    # cv2.waitKey(0)

    # Print Gear to console
    print(
        "Gear = "
        + pytesseract.image_to_string(
            gear,
            lang="formula1",
            config="--psm 7 -c tessedit_char_whitelist=0123456789",
        )
    )

    # cv2.imshow("gear", gear)
    # cv2.waitKey(0)

    print(INDEX)
    INDEX += 1
