ABSTRACT:

Camera calibration using known geometrical patterns are used extensively
in many computer vision and robotics applications. In this presentation,
we will first go through some fundamental theories in camera calibration
and in particular, the camera calibration technique based on planar
pattern of different orientations.

We then present our technique to efficiently calibrate a Pan-Tilt-Zoom
(PTZ) camera based on hand-drawn gridlines on a whiteboard. We also
illustrate our results in a human head tracking application.

BIOGRAPHY OF SPEAKER:

Dr Richard Xu is a lecturer in Computer Science and Centre Research
Fellow at Charles Sturt University. He obtained B.E (Computer
Engineering) from University of NSW and PhD (Computer Science) from
University of Technology, Sydney. He has been working in computer
vision, image processing and pattern recognition since 2001, and has
developed a series of multimedia systems, which incorporates the latest
computer vision algorithms. He has published more than thirty refereed
journal and conference papers, and currently principally supervising
one PhD and three Honour students in computer vision/image processing
projects. Dr Xu has also attracted funding from several industry
partners, such as Newcrest Mining and Sportstec.
