HKUST WORKSHOP INTRODUCES
AUTOMATED VISUAL INSPECTION TECHNOLOGY
More than 30 engineers and managers from leading local and international companies learned to apply automated visual inspection technology to their manufacturing processes at a workshop held at the Hong Kong University of Science and Technology.
The detection of defects by visual inspection is one of the most difficult tasks in manufacturing. Fortunately, advances in computer technology, sensing devices and machine vision have successfully automated this task for many manufacturing processes, leading to increased productivity, improved product quality and reduced unit cost.
“Two important considerations in any visual inspection system are the lighting and optical setups in the image acquisition process,” said Dr Reddiar Anbalagan, guest speaker and author of numerous publications on image processing and pattern recognition.
The workshop on “Lighting and Optics For Visual Inspection” covered several illumination methods including laser, strobe lighting and polarized lighting. Various kinds of sensors were introduced, as well as topics such as surface properties, optical filtering and optical enhancement.
Workshop participants represented companies involved in engineering, manufacturing and quality control, including world-renowned semiconductor, optical and electronic enterprises. Professionals from the Government’s Industry Department also took part.
The one-day workshop was held on 19 December. It was organised by HKUST’s Department of Computer Science and the School of Engineering Continuing & Professional Education Programme, and sponsored by the Vocational Training Council’s New Technology Training Scheme.
