Overview of this book

In this day and age, robotics has been gaining a lot of traction in various industries where consistency and perfection matter. Automation is achieved via robotic applications and various platforms that support robotics. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book focuses on the most stable release of ROS (Kinetic Kame), discusses advanced concepts, and effectively teaches you programming using ROS. We begin with aninformative overview of the ROS framework, which will give you a clear idea of how ROS works. During the course of this book, you’ll learn to build models of complex robots, and simulate and interface the robot using the ROS MoveIt! motion planning library and ROS navigation stacks. Learn to leverage several ROS packages to embrace your robot models. After covering robot manipulation and navigation, you’ll get to grips with the interfacing I/O boards, sensors, and actuators of ROS. Vision sensors are a key component of robots, and an entire chapter is dedicated to the vision sensor and image elaboration, its interface in ROS and programming. You’ll also understand the hardware interface and simulation of complex robots to ROS and ROS Industrial. At the end of this book, you’ll discover the best practices to follow when programming using ROS.

Chapter 10. Programming Vision Sensors Using ROS, Open CV, and PCL

In the last chapter, we discussed the interfacing of sensors and actuators using I/O boards in ROS. In this chapter, we are going to discuss how to interface various vision sensors in ROS and program them using libraries such as Open Source Computer Vision (OpenCV) and Point Cloud Library (PCL). The vision of a robot is an important aspect of the robot for manipulating objects and navigation. There are lots of 2D/3D vision sensors available on the market, and most of the sensors have an interface driver package in ROS. We will discuss the interfacing of new vision sensors to ROS and programming them using OpenCV and PCL. Finally, we will discuss the use of fiducial marker libraries to develop vision-based robotic applications.

We will cover the following topics in this chapter:

  • Integrating ROS, PCL, and OpenCV
  • Using a USB webcam in ROS
  • Learning how to calibrate a camera
  • Using RGB-D sensors in ROS
  • Using laser scanners in ROS
  • Working...
