Surface area calculator using OpenCV

In this OpenCV C++ tutorial article, we will learn how to calculate approximately the surface area of a random shape using various aspects of Computer Vision with OpenCV.

OpenCV is a set of libraries that can empower the software we are using or making today. Learning OpenCV is one of a good asset to the developer to improve aspects of coding and also helps in building a software development career.


Requirements

For a better understanding of this tutorial, you will need to know the basics of C++, have an idea about OpenCV and how it works and enjoy programming 😛, but it’s fine because I will provide you with a complete code ready to run.

Before we dive in, you can have a read about :

Introduction to OpenCV ( this link uses OpenCV for Python, but it provides a very good information about how OpenCV really do it’s magic. )

https://medium.com/edureka/python-opencv-tutorial-5549bd4940e3

Setup OpenCV C++ with VSCode ( yes, it’s one of the best source code editor)

https://medium.com/analytics-vidhya/vs-code-with-opencv-c-on-windows-10-explained-256418442c52

The idea behind

Before we begin, the idea behind this project was to automate the quality assurance of some 3D printed parts. Giving vision to the computer to automate this process made us gain enormous amount of money and time and the result was actually great, not too precise, but enough for our use case.

How ?

Okay, now that we introduced the use case, how will we achieve this ?

We will use a reference object that we know it’s surface area in advance, proportion it on the target object, and we will have the wanted surface area. Easy, right ?

This looks waaaay too simple. Let’s dive into a more detailed explanation.

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

Sorting Contours according to Size or Area OpenCV | How to Sort Contours OpenCV

This video explains the two ways of sorting contours according to the Size or Area using OpenCV. Contour sorting is very useful if in case you are building image detection or image recognition related applications. There are two ways you can sort contours. Number 1 is Sorting by area and number 2 sorting by spatial position. Sorting by area method is useful when you want to extract the large contours representing important parts of an image. It is also in getting rid of small contours thereby reducing the potential noise. On the other hand, sorting by spatial position helps us in sorting characters left or right. . This is the next video in the Python OpenCV Crash Course. Later on, in the upcoming videos, we will see how can we build face detection, object detection types of Computer Vision Projects.
