Practical Guide to Machine Vision Software: An Introduction with LabVIEW

Preface

We believe the basics of engineering and research is measurement. Also, all improvement starts from the measurement. We believe that LabVIEW is one of the best software tools to implement most kinds of measurement. There have been many basic books written for those wanting to learn LabVIEW measurement, which enables one to learn LabVIEW with ease. However, there are not many books on LabVIEW vision for the beginner. The purpose of this textbook is to guide the student in using LabVIEW's Vision Development Module rather than developing deep understanding of the underlying vision algorithms. For this reason, we do not discuss the details behind specific vision algorithms. We do try to explain the concepts involved in programming with the NI Vision Development Module.

In this book the NI Vision Development Module is used to analyze objects in an image. The Vision Development Module includes hundreds of functions to process acquired images. However, for most beginners it may be difficult to understand and use the vision functions. The Vision Assistant, which is a component installed with NI Vision Development Module, is very easy to use and can create LabVIEW or C code in the process of guiding you through image processing steps. Vision Assistant provides access to almost all the vision functionality available in LabVIEW.

The approach of this book is to use the LabVIEW Vision Assistant to create the initial code that can perform vision measurement and provide the beginner ...
