摘要
A method is provided for measuring optical characteristics of a glass sheet as the glass sheet is conveyed in a system for fabricating glass sheets including one or more processing stations and one or more conveyors for conveying the glass sheet during processing. The method comprises providing a background screen including contrasting elements arranged in a pre-defined pattern and a camera for acquiring an image of the background screen; acquiring data associated with a shape of a glass sheet travelling on a conveyor upstream from the background screen; removing the glass sheet from the conveyor; and positioning the glass sheet between the camera and the screen and thereafter acquiring an image of the background screen; re-positioning the glass sheet for continued movement of the glass sheet on the conveyor; and performing one or more processing operations using the acquired image data to analyze the optical characteristics of the glass sheet.
