Facing an error in Uploading the image/file to detect the number plate. need help

[Mehfooz Ali]

Hello Experts,

"ERROR FILE ATTACHED"

I am working on a project on Image Processing with OpenCV. Project License Number Plate Detection.

I have developed this in simple python code. Now I want to integrate OpenCV Code with Django and I need a Web Based project. 

Can you please guide me on how to do it? I am an Intermediate Django Developer and don't know much about AI, ML, or OpenCV Project integrations. 

I have tried to make Models, Forms, URLS, and Views. But I don't know how to process it.

Views.py Code:

from tempfile import NamedTemporaryFile

from django.shortcuts import render, redirect

from .models import LicensePlate

from .forms import LicensePlateForm

import numpy as np

import cv2

import pytesseract

def home(request):

    if request.method == 'POST':

        form = LicensePlateForm(request.POST, request.FILES)

        if form.is_valid():

            # Save the uploaded image to a temporary file

            image_file = request.FILES['image']

            temp_file = NamedTemporaryFile()

            for chunk in image_file.chunks():

                temp_file.write(chunk)

            temp_file.flush()

            # Load the image and convert it to grayscale

            image = cv2.imread(temp_file.name)

            gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

            # Load the Haar cascade for detecting Russian license plates

            cascade_path = 'haarcascade_russian_plate_number.xml'

            cascade = cv2.CascadeClassifier(cascade_path)

            # Detect the license plate in the image

            license_plates = cascade.detectMultiScale(gray, 1.1, 4)

            # Extract the text from the license plate using OCR

            for (x, y, w, h) in license_plates:

                license_plate = image[y:y+h, x:x+w]

                text = pytesseract.image_to_string(license_plate)

            # Save the extracted text to the database

            car = LicensePlate(image=request.FILES['image'], license_plate=text)

            car.save()

            # Render the template with the extracted text and the uploaded image

            return render(request, 'home.html', {'form': form, 'text': text, 'image': image_file})

    else:

        form = LicensePlateForm()

    return render(request, 'home.html', {'form': form})
