Over the past year the PyImageSearch blog has had a lot of popular blog posts. Using k-means clustering to find the dominant colors in an image was (and still is) hugely popular. One of my personal favorites, building a kick-ass mobile document scanner has been the most popular PyImageSearch article for months. And the first (big) tutorial I ever wrote, Hobbits and Histograms, an article on building a simple image search engine, still gets a lot of hits today.
But by far, the most popular post on the PyImageSearch blog is my tutorial on installing OpenCV and Python on your Raspberry Pi 2 and B+. It’s really, really awesome to see the love you and the PyImageSearch readers have for the Raspberry Pi community — and I plan to continue writing more articles about OpenCV + the Raspberry Pi in the future.
Anyway, after I published the Raspberry Pi + OpenCV installation tutorial, many of the comments asked that I continue on and discuss how to access the Raspberry Pi camera using Python and OpenCV.
In this tutorial we’ll be using picamera, which provides a pure Python interface to the camera module. And best of all, I’ll be showing you how to use picamera to capture images in OpenCV format.
