In this tutorial, we will use an example to show you how to detect and decode barcode in python opencv.

1.Install python pyzbar library

pip install pyzbar

In order to decode barcode, we need install python pyzbar library.

2.Read barcode image

import cv2
from pyzbar.pyzbar import decode
image = cv2.imread('C:/Users/N/Desktop/barcode.png')

3.Use decode() method to decode barcode

detectedBarcodes = decode(image)
for barcode in detectedBarcodes:
	
	(x, y, w, h) = barcode.rect
	cv2.rectangle(image, (x, y), (x + w, y + h), (255, 0, 0), 5)
 
	print(barcode.data)
	print(barcode.type)

Here barcode.data is the content of barcode.

4.Display barcode image in opencv

cv2.imshow("Image", image)
 
cv2.waitKey(0)
cv2.destroyAllWindows()
