So people have all found the venue and a couple of people even want to buy some images. You wouldn’t want people getting lost would you. The venue is quite hard to find, good job you included a QR code that links to a Google map. So you have followed all of the tips and tutorials on Digital Photography School and you have decided to share your beautiful photographs in an exhibition! Great news! Why not send people invites and include a QR code that will allow people to add the event into their diary using vcalendar. So we now know what a QR code is but how could it help me, a photographer? Event If you have downloaded the QR reader for your smartphone give it ago! So I have created this QR code that will take you to the Digital Photography School forum. Once you have downloaded a QR reader you simply take a photo of the code and the reader processes it. This QR code can hold a range of information which can be accessed using a QR reader, these readers are widely available (and free) for the majority of smart phones. QR means Quick Response Code and is a two dimensional barcode which is very similar to the standard barcode used on general products. In a nutshell, to get best performance of Dynamsoft Barcode Reader SDK, you should start with the simplest settings and then gradually increase and tune algorithm parameters.QR codes can be a great marketing tool, even if you don’t know what one is I’m sure you will have seen one on your travels. For better studying the parameter differences among different modes, we can scroll down the page and save all parameters to a json file. You can click Advanced Settings to expand the parameters of a mode. There are five modes available for selection. Fortunately, we can leverage the parameter tuning tool of Dynamsoft Barcode Reader online demo to customize parameters for specific images.

There are quite a lot of parameters to tune, but you cannot find a crash course on how to tune these parameters. decode_buffer_manually ( buffer, width, height, stride, pixel_format, "" ) end = time. imread ( 'Air-Force-Reserve-San-Diego.jpg' ) def detect ( windowName, image, pixel_format ): try : buffer = image. init_license ( "DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ=" ) # Import cv2 import numpy as np import dbr import time reader = dbr. We can then export the template to a JSON file and load it in our Python code: Now the QR code is recognized extremely fast.
Go to Advanced Settings > Binarization mode > Threshold.It successfully recognizes the QR code but takes 828 milliseconds.īoth of them are not ideal according to our test. It takes 15 milliseconds but fails to recognize the QR code. Now, we upload the perspective distorted QR image to see the difference between the best speed and best coverage. You may try the templates in our server-side barcode scanner demo. The more algorithms are enabled for barcode recognition, the more time it takes. There is a tradeoff between the barcode decoding speed and recognition accuracy. Two of the mostly used templates are speed and coverage. Dynamsoft’s QR Code SDK is extensively customizable and offers a variety of scanning templates.
