AN INTRODUCTION TO 3D COMPUTER VISION TECHNIQUES AND ALGORITHMS

Recent decades have seen rapidly growing research in many areas of computer science, including
computer vision. This comes from the natural interest of researchers as well as demands
from industry and society for qualitatively new features to be afforded by computers. One especially
desirable capability would be automatic reconstruction and analysis of the surrounding
3D environment and recognition of objects in that space. Effective 3D computer vision
methods and implementations would open new possibilities such as automatic navigation of
robots and vehicles, scene surveillance and monitoring (which allows automatic recognition
of unexpected behaviour of people or other objects, such as cars in everyday traffic), medical
reasoning, remote surgery and many, many more.
This book is a result of our long fascination with computers and vision algorithms. It started
many years ago as a set of short notes with the only purpose ‘to remember this or that’ or to
have a kind of ‘short reference’ just for ourselves. However, as this diary grew with the years
we decided to make it available to other people. We hope that it was a good decision! It is our
hope that this book facilitates access to this enthralling area, especially for students and young
researchers. Our intention is to provide a very concise, though as far as possible complete,
overview of the basic concepts of 2D and 3D computer vision. However, the best way to get
into the field is to try it oneself! Therefore, in parallel with explaining basic concepts, we
provide also a basic programming framework with the hope of making this process easier.We
greatly encourage the reader to take the next step and try the techniques in practice.
