We’ll then load the selected image using OpenCV, perform edge detection, and finally display both the original image and edge map in our GUI.
A few weeks ago Raspbian Jessie was released,. However, the update to Jessie also broke the previous OpenCV + Python install instructions for Raspbian Wheezy: • • Since PyImageSearch has become the online destination for learning computer vision + OpenCV on the Raspberry Pi, I decided to write a new tutorial on installing OpenCV 3 with Python bindings on Raspbian Jessie. As an additional bonus, I’ve also included a video tutorial that you can use to follow along with me as I install OpenCV 3 on my own Raspberry Pi 2 running Raspbian Jessie. This video tutorial should help address the most common questions, doubts, and pitfalls that arise when installing OpenCV + Python bindings on the Raspberry Pi for the first time. Assumptions For this tutorial I am going to assume that you already own a with. Other than that, you should either have (1) physical access to your Pi 2 and can open up a terminal or (2) remote access where you can SSH in.

To make the installation process easier, I’ve included timings for each step (when appropriate) so you know when to stick by your terminal, grab a cup of coffee, or go for a nice long walk. If you’re an experienced Linux user or have already installed OpenCV on a Raspberry Pi (or another other system) before, you can likely just follow the steps outlined below. However, if this is your first time installing OpenCV (or you don’t have much prior exposure to the Linux operating systems and the command line), I highly recommend that you watch the video above and follow along with me as I show you how to install OpenCV 3 on your Rasberry Pi running Raspbian Jessie. That said, let’s get started installing OpenCV 3. Step #1: Install dependencies The first thing we should do is update and upgrade any existing packages, followed by updating the Raspberry Pi firmware.
