How long does it take to get started with OpenCV

Normally, you only need to study for 2 months.

OpenCV is just a tool that implements many useful algorithms in the field of computer vision.

Before learning OpenCV, please learn the basics of computer vision, and it is recommended to learn at least one theoretical book on computer vision and one theoretical book on image processing.

With the above basic theoretical foundation, and then learning OpenCV, you can watch the tutorial, but more should look at the reference documents. The reference documentation of opencv is very complete, and if you don't understand it, you can search on the Internet, and you have to grasp the main line of what this function is for, under what circumstances, and what the input and output are.

In addition, about and above versions.

I recommend that beginners start with a lot of MAT, as some functions are difficult for novices to understand.

In fact, the version is strong enough, I have done a lot of projects, all of them are used, for newbies, it is enough for you to gnaw for a year. Of course, there are many algorithms in the above version, but in fact, many algorithms are rarely used. So it's a good idea to start with.

It's the most basic, and more things have been added in the later stage and now, including the implementation of a lot of new algorithms, and the goal tracking, which I'm also learning by myself now, and I feel like I can start from the version, because the main application to the actual is basically included in it. Later, if you feel that it is not enough, you can continue to learn the version. Best wishes.

There is a book called learning opencv, and there is also a corresponding Chinese version, but it is still recommended to read the English version. It is not meant to read the whole book, but as a reference, like a dictionary. First of all, you must be very clear about what you want to do, which methods and functions in OpenCV you need to use, and then search for specific chapters in the corresponding directory.

You may be confused and don't know how to do it, so you can try to run the first two chapters of the routine first, and you probably know how to operate, and then you will slowly get started. However, many functions, the algorithm will indeed be a headache for the first time, try more, and there are many routines on the Internet.

OpenCV is very simple.,Introduce you to this book.,OpenCV Tutorial-Basics" Liu Ruizhen's,It's very basic.,Don't look so esoteric at first.,When the time comes, I'm not interested in learning.,If you don't understand, you can ask me.。

Chinese** Buy some books, the key is to program more!

1. opencv tutorials

This is first-hand. If you learn anything, the first-hand information must be up to date with the times and the most worth reading.

2.Learn OpenCV (Chinese version) (Douban).

Although this is the grammar of the OpenCV1 era, the essence of this book is to take you through the basics from image processing to computer vision step by step.

3.OpenCV2 Computer Vision Programming Manual (Douban).

This book is based on the syntax of OpenCV2.,It's an upgraded version of the grammar of "Learning OpenCV", and the source ** that comes with the book is worth reading.

4.Mastering OpenCV with Practical Computer Vision Projects (Douban).

The examples of this book are very interesting, augmented reality, and belong to the direction of the project that is very popular now. Follow along, and maybe it can come in handy.
