Which trans module do you use?

[pavlobu]

I'm using your python code to develop my app but I have the problem with this part

warped = trans.four_point_transform(img, src)
in file qrcode.py line 274

when it reaches this part it says:

AttributeError: 'module' object has no attribute 'four_point_transform'

indeed trans I installed from pip doesn't have it.

Can you help?

HI,
sorry you had to read my shitty code, I adapted this from a guy who wrote it for RASPBERRYPI, and made the code look even messier, I never intended to have anyone find it...

You can use the transform1.py under computer vision, and change the code to
warped,rect,maxWidth,maxHeight,dimension = transform1.four_point_transform(img,src)

although you may only need to use wrapped

I made some changes in the four-point-transform function so that you can obtain a top down bird eye view of the qr, which allows you to have your qr code identified at various tilting angles.thi function also contains a lot of nonsensical stuff I hard coded in to work for my purpose at the moment...you can simply ignore it.

Hope this helps

HI,
I have the same problem as hexenskull. How did you solve it? Where can i find the transform1.py?

Any News?

Here you go...still I don't suggest using the code...

Hello Guys,
I have found solution for this issue. Actually trans is not a module here.
Just download this file motion/transform.py & move into your folder.
Instead of using: import trans use import transform

Change warped = trans.four_point_transform(img,src) to warped= transform.four_point_transform(img,src)

Note: Here trans is not a module, it's a file named transform & four_point_transform is a function of that file.

I hope this will help. Now we can close this.
