Why is file not being processed by opencv from Django form?

Question

Django

Uploading a file using forms in Django and trying to process it. In the following way:

[PYTHON]
        if form.is_valid():
            rb = form.save(commit=False)
            pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files (x86)\Tesseract-OCR5\tesseract.exe'
            rb.text = pytesseract.image_to_string(Image.open(rb.image), lang='rus')
            im = cv2.imread(rb.image)
            rb.for_what= rec(rb.image)
            rb.delegate= 's'
            rb.date = 's'
            rb.delegate = 'f'
            rb = form.save()
            return redirect('main:profile')
[/PYTHON]

why through Image.open(rb.image) everything is fine and the file is opened, while cv2.imread(rb.image) gives an error returned NULL without setting an error

Answer 1

Understand what cv2.imread and Image.open expect as a parameter and what rb.image returns
