Real-time industrial visual inspection: A Review

This paper provides a review of state-of-the-art techniques and technologies associated with real-time automated visual inspection as applied in industrial situations. A survey of the most widely used machine vision algorithms is presented, with emphasis on those algorithms most suited to real-time application. Practical illumination schemes for real-time industrial inspection are also considered. The paper then focusses on areas which have received scant attention from the research community but which look set to become increasingly important in the next few years, namely system robustness and verification, including temporal verification.
