Hands-On Robotics Programming with C++

By: Dinesh Tavasalkar, Lentin Joseph

Overview of this book

C++ is one of the most popular legacy programming languages for robotics, and a combination of C++ and robotics hardware is used in many leading industries. This book will bridge the gap between Raspberry Pi and C/C++ programming and enable you to develop applications for Raspberry Pi. You'll even be able to implement C programs in Raspberry Pi with the WiringPi library. The book will guide you through developing a fully functional car robot and writing programs to move it in different directions. You’ll then create an obstacle-avoiding robot using an ultrasonic sensor. In addition to this, you’ll find out how to control the robot wirelessly using your PC or Mac. This book will also help you work with object detection and tracking using OpenCV, and guide you through exploring face detection techniques. Finally, you will create an Android app and control the robot wirelessly with an Android smartphone. By the end of this book, you will have gained experience in developing a robot using Raspberry Pi and C/C++ programming.

Image processing with OpenCV

In this section, we will look at the important functions of the OpenCV library. After that, we will write a simple C++ program using the OpenCV libraries and perform different image-processing operations on an image.

Important functions in OpenCV

Before writing any OpenCV program, it is important to understand some of the main functions in OpenCV and the output that these functions can give us. Let's start by looking at the functions:

  • imread(): The imread() function is used to read an image or a video feed from the Pi camera or webcam. Inside the imread() function, we have to provide the location of the image. If the image and program files are in the same folder, we only need to provide...
