Hands-On Vision and Behavior for Self-Driving Cars

By: Luca Venturi, Krishtof Korda

Overview of this book

The visual perception capabilities of a self-driving car are powered by computer vision. The work relating to self-driving cars can be broadly classified into three components - robotics, computer vision, and machine learning. This book provides existing computer vision engineers and developers with the unique opportunity to be associated with this booming field. You will learn about computer vision, deep learning, and depth perception applied to driverless cars. The book provides a structured and thorough introduction, as making a real self-driving car is a huge cross-functional effort. As you progress, you will cover relevant cases with working code, before going on to understand how to use OpenCV, TensorFlow and Keras to analyze video streaming from car cameras. Later, you will learn how to interpret and make the most of lidars (light detection and ranging) to identify obstacles and localize your position. You’ll even be able to tackle core challenges in self-driving cars such as finding lanes, detecting pedestrian and crossing lights, performing semantic segmentation, and writing a PID controller. By the end of this book, you’ll be equipped with the skills you need to write code for a self-driving car running in a driverless car simulator, and be able to tackle various challenges faced by autonomous car engineers.

Chapter 5: Deep Learning Workflow

In this chapter, we will go through the steps that you might perform while training your neural network, and when putting it into production. We will discuss more about the theory behind deep learning, to explain better what we actually did in Chapter 4, Deep Learning with Neural Networks, but we will stay mostly focused on arguments related to self-driving cars. We will also introduce some concepts that will help us to achieve better precision on CIFAR-10, a famous dataset of small images. We are sure that the theory exposed in this chapter, plus the more practical knowledge associated with Chapter 4, Deep Learning with Neural Networks, and Chapter 6, Improving Your Neural Network, will give you enough tools to be able to perform tasks that are common in the field of self-driving cars.

In this chapter, we will cover the following topics:

  • Obtaining or creating the dataset
  • Training, validation, and test datasets
  • Classifiers
  • Data...
