![]() 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 : breakĭynamsoft Barcode Reader can detect multiple barcodes and QR codes from a single image. imshow ( 'Barcode & QR Code Scanner', frame ) ch = cv. FONT_HERSHEY_SIMPLEX, 0.5, ( 0, 0, 255 )) if len ( barcodeTasks ) < threadn : task = pool. get () if results != None : for result in results : points = result. read () while len ( barcodeTasks ) > 0 and barcodeTasks. decode_buffer ( frame ) except BarcodeReaderError as bre : print ( bre ) return results while True : ret, frame = cap. An incomplete uninstallation of a program may cause problems, which is why thorough removal of programs is recommended.Def process_frame ( frame ): results = None try : results = reader. There could be other causes why users may not be able to uninstall CodeTwo QR Codes Desktop Reader. Another process is preventing the program from being uninstalled.Due to an error, not all of the files were successfully uninstalled.A file required for the uninstallation to complete could not be run.The program’s built-in uninstaller does not start or does not operate properly.Possible problems that can arise during uninstallation of CodeTwo QR Codes Desktop Reader ![]()
