PYTHON QR CODE READER API HOW TO
OpenCV repository contains a stitching.py file showing how to use the OpenCV stitcher API. Stitching Multiple Barcode and QR Code Images into a Panorama To solve this problem, we get camera closer to get high quality image for scanning, and then use OpenCV stitching API to stitch multiple barcode and QR code images into a panorama.
In this way, the barcode and QR code may become too small to read. As you can see in the above image, to capture all barcode and QR code, we need to increase the lens depth of field. However, the image quality affects the detection accuracy. waitKey ( 1 ) if ch = 27 : breakÄynamsoft Barcode Reader can detect multiple barcodes and QR codes from a single image. imshow ( 'Barcode & QR Code Scanner', frame ) ch = cv.
