Creating an OpenCV 4 Project in Visual Studio 2017 & 2019

Mon, 24 Dec 2018 00:00:00 +0000

In my previous tutorial, I outlined how to build the OpenCV 4 library on Microsoft Windows 10. In that tutorial, however, I did not mention how to use that library in an actual project. This time around I will be showing you how to create an OpenCV 4 project within Microsoft Visual Studio 2017.

Please note that I am going to assume that your OpenCV install is set up in the way I outlined in my previous tutorial. That is to say that the necessary files are located within an OpenCV folder in your C:\ drive. If this is not the case you’ll have to make some minor modifications to the steps outlined here to suit your setup.

Let’s get started!

Installing OpenCV 4 on Windows 10

Mon, 24 Dec 2018 00:00:00 +0000

I love working with the OpenCV library, but it can be a royal pain in the butt to get it installed and running on your machine. This is especially true for Microsoft Windows. Despite a Google search turning up plenty of results for articles promising to show you how to do it, they all seem to have issues or be incomplete. This results in a rather frustrating experience when you just want to get things up and running.

The purpose of this tutorial is to walk you through, step-by-step, how to install OpenCV version 4 on your Microsoft Windows 10 system. So, let’s quit talking about it and jump right in!

Mon, 07 Aug 2017 00:00:00 +0000

Have you ever written code to interface with a webcam? Well, if you have then you know that it can be a royal pain in the ass. And God forbid you want it to be a cross-platform solution! The good news is that there is a ready-made solution that can help us out: OpenCV. Yes, you heard me right. Not only is OpenCV and amazing computer vision library, but it also provides a handy, cross-platform way of interfacing with webcams. Let’s take a look at how simple OpenCV makes this. I’ll be using Python for these examples, but the API is similar in other languages.
