module 'cv2.cv2' has no attribute 'detail_BundleAdjusterRay'

[CheskaAbarro]

Hey,

First of all, thank you for this wonderful source code. It wasreally helpful for me as a beginner.

I am having a problem with you Stitching Tutorial jupyter notebook. In this line

from stitching.image_handler import ImageHandler

img_handler = ImageHandler()
img_handler.set_img_names(weir_imgs)

medium_imgs = list(img_handler.resize_to_medium_resolution())
low_imgs = list(img_handler.resize_to_low_resolution(medium_imgs))
final_imgs = list(img_handler.resize_to_final_resolution())

I am havig this error:

AttributeError: module 'cv2.cv2' has no attribute 'detail_BundleAdjusterRay'

and I tried searching it but there is no solution that I found on this one. Can you help me solve this? Greatly appreciated.

It seems strange that the module is named cv2.cv2.

here is stated that you might need to pip install opencv-contrib-python.

How did you installed opencv?

[CheskaAbarro]

I had the following

opencv-python 4.7.0.72 opencv-contrib-python 4.7.0.72 stitching 0.4.0

I tried bunch of times to install different versions of opencv but the error still persist.

you could try only installing stitching. Pip will figure out the dependencies.

Do other parts of opencv work? Can you e.g. imread a simple image independent of the stitching package?

[CheskaAbarro]

I had a stitching 0.4.0 installed already and I tested, cv2.imread() is working.

The only line of code that I'm having a problem is with the

from stitching.image_handler import ImageHandler

[lukasalexanderweber]

sorry I don't really get it becaue detail_BundleAdjusterRay is not even called in the image handler

Hello.

I had successfully executed your code. I downgraded the requirements into the following:

opencv-python = 3.4.2.16
opencv-contrib-python = 3.4.2.16
numpy = 1.21.6
stitching 0.2.0

Its a different error but somehow this solution works.

You have a wonderful work. Thanks again for sharing it.

Hello, I am having a similar problem on Mac.

Import "stitching.image_handler" could not be resolved Pylance(reportMissingImports)

I have tried uninstalling stitching, opencv-python, opencv-contrib-python, reinstalling only stitching… but nothing.

[lukasalexanderweber]

You need to use the new Tutorial Version
