method and device for the correction of höhenbildstandsfehlern

摘要

procedure for the correction of hu00f6henbildstandsfehlern in the reproduction of an intermittently transported by a perforated luftbildfilmes in the filmperforation intervening filmtransportzahnrolle, the pump is driven by an electric motor, whose rotor with a winkelgebereinri involved is connectedthe winkelstellung of the rotor position signals corresponding to the electric motor ansteuernde device.to correct geru00e4tespezifischer hu00f6henbildstandsfehler the bildstandspositionen with a geometrically exact meu00dffilm on a variety of images measured by the respective bildstandspositionen is stored and the position of the winkelgeberscheibe a correction value to the filmtran sportzahnrolle changed.to correct betriebsabhu00e4ngiger hu00f6henbildstandsfehler are fehlertabellen for projektionsbetrieb occurring bildstandsfehler which is stored bildstandspositionen is continuously measured and the collected measurements with the stored values in the fehlertabellen comparedone of the values represents fehlertabelle optimally identified and this fehlertabelle) korrekturtabelle selected whose correction be made to the device.
