Updated: September 16th, 2019 Ever since I wrote the first PyImageSearch tutorial on installing OpenCV + Python on the Raspberry Pi B+ back in February 2015 it has been my dream to offer a downloadable, pre-configured Raspbian .img file with OpenCV…

Today’s blog post will take a short diversion from our recent trend of Deep Learning tutorials here on the PyImageSearch blog and instead focus on a topic that I’ve been receiving a ton of emails about lately — common errors…

Here’s a common question I get asked on the PyImageSearch blog: How do I make a Python + OpenCV script start as soon as my system boots up? There are many ways to accomplish. By my favorite is to use…

Last week we learned a bit about Python virtual environments and how to access the RPi.GPIO and GPIO Zero libraries along with OpenCV. Today we are going to build on that knowledge and create an “alarm” that triggers both an…

I can’t believe this is the first time I am writing a blog post on GPIO and the Raspberry Pi. It’s a pretty big mistake on my part. I should have written this post much earlier. You see, on average,…

Can you believe it’s been over four years since the original Raspberry Pi model B was released? Back then the Pi Model B shipped with only 256MB of RAM and a 700MHz single core processor. Just over one year ago…

Let me just start this blog post by saying that writing to video with OpenCV can be a huge pain in the ass. My intention with this tutorial is to help you get started writing videos to file with OpenCV…

One of my favorite parts of running the PyImageSearch blog is a being able to link together previous blog posts and create a solution to a particular problem — in this case, real-time panorama and image stitching with Python and…
