Abstract
A method is provided for determining a sheet height of a sheet conveyed by a sheet transportation unit. An optical sensor is used for sensing the surface geometry of the sheet, resulting in a two-dimensional height image of the sheet. The height image has pixels that have a value representing a local height of the sheet. The method comprises the steps of: a) selecting from the height image pixels that have a deviating value; b) substituting the deviating value of a selected pixel by a realistic value that is derived from not selected pixels; and c) determining a sheet height by finding a maximum value from the values of the not selected pixels and the substituted values. Furthermore, a print system is provided that comprises a control unit that is configured to apply the invented method.
