We’ll utilize NumPy for numeric processing, argparse for parsing command line arguments, and cv2 for our OpenCV bindings. The first thing we’ll do is import the packages we’ll need. # construct the argument parse and parse the argumentsĪp.add_argument("-i", "-image", required = True, Open up a new file, name it detect_barcode.py, and let’s get coding: # import the necessary packages Let’s go ahead and start writing some code. It’s important to note that this algorithm will not work for all barcodes, but it should give you the basic intuition as to what types of techniques you should be applying.įor this example, we will be detecting the barcode in the following image: Figure 1: Example image containing a barcode that we want to detect.

I have gone through the code and provided some updates and improvements to the original algorithm. My implementation of the algorithm is originally based loosely on this StackOverflow question. The goal of this blog post is to demonstrate a basic implementation of barcode detection using computer vision and image processing techniques. Looking for the source code to this post?

In the rest of this blog post I’ll show you how to detect barcodes in images using nothing but Python and OpenCV. Imagine how silly you would feel, standing in line, waiting to checkout, only to scan the barcode on the latest season of Game of Thrones only to find out that Target has it for $5 cheaper?

During Black Friday.Īnd I have to ask, is all this chaos and bedlam worth it?Īny shopping I do this Black Friday will be from (safely) behind my laptop screen, likely nursing a hangover from the night before with a cup of coffee and a handful of Tylenol.īut if you decide you are going to venture out into the real-world and brave the bargain hunters, you’ll want to download the source code to this blog post first… All of this simply because she wanted to purchase the latest Halo game for Timmy, her little 9 year old grandson, who’s parents passed away this time last year. From frostbitten families camping out all night in the blistering cold, to the little old lady trampled by raging bargain hunters as the doors open, akin to the Gallimimus stampede in Jurassic Park. Of course, the media won’t help - they will sensationalize every last little piece. And their thunderous footsteps will cause earthquakes across the Great Plains. Their war cries of discounts and sales will reach the heavens. But instead of human flesh, they crave petty consumer sustenance. They’ll rally, beating at the locked doors with their hands and heads until their bodies are raw and bloody, like zombies from 28 Days Later. They’ll lineup outside the Wal-Mat doors on Thanksgiving at midnight.
Stampedes of middle-aged midwestern women, their toothless gums bloodthirsty for 75% off the latest season of Game of Thrones at the local Wal-Mart. For some context, I had just finished watching the South Park Black Friday episodes prior to writing this post so I definitely had some inspiration regarding zombie shoppers, Black Friday chaos, and Game of Thrones.
