Surface inspection systems are widely used in many industries including steel, tin, aluminum, and paper. These systems generally use machine vision technology to detect defective surface regions and can generate very high data output rates which can be difficult for line operators to absorb and use. A graphical, windowing interface is described which provides the operators with an overview of the surface quality of the inspected web while still allowing them to select individual defective regions for display. A touch screen is used as the only operator input. This required alterations to some screen widgets due to subtle ergonomic differences of touch screen input over mouse input. The interface, although developed for inspecting coated steel, has been designed to be adaptable to other surface inspection applications. Facility is provided to allow the detection, classification, and display functions of the inspection system to be readily changed. Modifications can be implemented on two main levels; changes that reflect the configuration of the hardware system and control the detection and classification components of the surface inspection system are accessible only to authorized staff while those affecting the display and alarm settings of defect types may be changed by operators and this can generally be done dynamically.
