pyxploiter / barcode-detection-and-decoding Goto Github PK

Hello, i want to ask, can this code be modify to using camera or webcam for detect and decode the barcode and show the result of barcode code ?

I am getting this Error.

One File in the repository is in python 2 and the other in python 3
How do you suppose to run in in Linux environment ?

the file detect_barcode_opencv.py is in python 3
and the file barcode_detect_and_decode.py is in python 2, due to the zbar dependency.
How do you use this library in production environment ?

Getting an error barcode_opencv.py --image bilet.jpg
Traceback (most recent call last):
File "detect_barcode_opencv.py", line 62, in
c = sorted(cnts, key = cv2.contourArea, reverse = True)[0]
TypeError: Expected cv::UMat for argument 'contour'

I had to remove two returns from cnts = cv2.findContours as I believe it has changed to return just 1 item. I believe the error has to do with cnts being a tuple and not a list. I've seen others use imutils to turn into a list, but it has not worked on my images.
