Abstract
The invention relates to a method and apparatus for monitoring safety glass production or controlling a treatment process, such as a tempering process. Information representing a load of glass panels is used in controlling a treatment process, such as heating of glass panels, or in monitoring production. The information, which includes at least one of the following: shape, size, and position, is read with one or more cameras (). This is possible as glass is made visible by means of reflected light as high intensity light is applied to the glass surface. The line camera () is used for receiving low intensity background light radiation incident through the glass conveying plane, a substantial increase in its intensity, as light is reflected by glass, being deciphered as glass.
