Showing Webcam Video Stream using PyQt Usually, we can use OpenCV for Python to capture webcam frames. Find any QR code or bar code and hold it close to your webcam and it should pick up. Pure python Works with PIL / Pillow images, OpenCV / numpy ndarray s, and raw bytes Decodes locations of barcodes No dependencies, other than the zbar library itself Tested on Python 2.7, and Python 3.4 to 3. Below, we’ll be developing an application that scans the QR Code value from a bitmap image as well as detects QR Code through a camera and perform the relevant actions. Now I am going to add a little bit more code to scan barcodes from the webcam video stream. This project is forked from zbar library, I added few modifications, so webcam can be used as an image reader to detect QR and Bar codes. QR Code is the more popular format and is commonly seen in many applications. #Python qr code reader webcam driver
