Lastly I would like to thank Steven Lovegrove for his brilliant Laser Tracking idea and constantly supplying me with cups of tea.Ĭontents 1 Introduction 1.1 The Application. I would also like to thank Prof Alexander Wolf for agreeing to be my second marker. The software developed here is used to evaluate the effectiveness of the tracking solution, showing that the idea of optical tracking with inexpensive cameras is a viable mechanism for computer interaction.Īcknowledgments I would like to thank my supervisor Dr Tony Field for his invaluable assistance and enthusiasm. This project aims to demonstrate that high accuracy optical tracking can be achieved using inexpensive video cameras in an unconstrained environment. Specialist equipment and the requirement for a highly controlled environment are obstacles stopping tracking from breaking into the consumer market. Tony Field Second Marker: Prof Alexander Wolf June 2007Ībstract Motion tracking has been employed by industry for many years but has remained an expensive and difficult process.
