Overview of this book

Robot Operating System is one of the most widely used software frameworks for robotic research and for companies to model, simulate, and prototype robots. Applying your knowledge of ROS to actual robotics is much more difficult than people realize, but this title will give you what you need to create your own robotics in no time! This book is packed with over 14 ROS robotics projects that can be prototyped without requiring a lot of hardware. The book starts with an introduction of ROS and its installation procedure. After discussing the basics, you’ll be taken through great projects, such as building a self-driving car, an autonomous mobile robot, and image recognition using deep learning and ROS. You can find ROS robotics applications for beginner, intermediate, and expert levels inside! This book will be the perfect companion for a robotics enthusiast who really wants to do something big in the field.

Preface

Chapter 6. Object Detection and Recognition

Object recognition has an important role in robotics. It is the process of identifying an object from camera images and finding its location. Using this, a robot can pick an object from the workspace and place it at another location.

This chapter will be useful for those who want to prototype a solution for a vision-related task. We are going to look at some popular ROS packages to perform object detection and recognition in 2D and 3D. We are not digging more into the theoretical aspects, but you may see short notes about the algorithm while we discuss their applications.

You will learn about the following topics:

  • Getting started with object detection and recognition

  • The find_object_2d package in ROS

  • Installing find_object_2d

  • Detecting and tracking an object using a webcam

  • Detecting and tracking using 3D depth sensors

  • Getting started with 3D object recognition

  • Introducing the object-recognition package in ROS

  • Installing object-recognition packages

  • Detecting...
