Description

Verfahren zum Ausarbeiten von Meßbildpaaren Es ist bereits vorgeschlagen worden, beim Ausarbeiten von Meßbildpaaren mittels eilfies Doppelprojektors das räumlich erscheinende Bild, das man z. B. beim Itot-Grün-Verfahren sieht, unmittelbar mit einer geeigneten formbaren Masse, z. B. Gips, nachzubilden.Method for working out pairs of measurement images It has already been proposed when working out pairs of measuring images using eilfies double projector spatially appearing image that you z. B. sees the Itot-Grün method immediately with a suitable malleable mass, e.g. B. plaster of paris to replicate.

Die Erfindung bezweckt eitle solche Nachbildung dadurch zum Reliefplan zu machen, daß das Relief oder Modell mit einem entsprechenden photographischen Bild überzogen wird.The invention aims to create such a replica for the relief plan to make that the relief or model with an appropriate photographic Image is coated.

Zu diesem Zwecke wurden bisher Fliegerbilder oder danach angefertigte Bildentzerrungen auf lichtempfindlichem Papier hergestellt, worauf dann das Papier einem Dehnungsprozeß unterworfen und auf das in anderer bekannter Weise hergestellte Modell aufgeklebt wurde. Dieses Verfahren war langwierig und infolge der oft ungleichmäßigen Dehnung ungenau, wobei auch noch das nachträgliche Aufkleben nachteilig war.For this purpose, aviator pictures or afterwards have been made up to now Image distortion correction is made on photosensitive paper and then the paper subjected to a stretching process and produced in another known manner Model was glued on. This process was tedious and often uneven as a result of the Stretching inaccurate, and the subsequent gluing was also disadvantageous.

Die Erfindung vermeidet dieses Dehnen und nachträgliche Aufkleben des fertigen Bildes auf folgende Weise: Nachdem am Ausmeßgerät, z. B. am Doppelprojektor, unmittelbar nach dem erscheinenden Raumbilde das Modell geformt und gegebenenfalls auf eine geeignete bekannte Weise befestigt ist, wird eine, zweckmäßig flüssige, lichtempfindliche (also noch unbelichtete') Schicht aufgetragen und alsdann durch das projizierte Meßbild oder beim Doppelprojektor z. B. auch durch ein im Rot-Grün-Verfahren projiziertes Meßbildpaar belichtet.The invention avoids this stretching and subsequent sticking of the finished image in the following way: After the measuring device, z. B. on the double projector, Immediately after the spatial image that appears, the model is formed and, if necessary is attached in a suitable known manner, an expediently liquid, light-sensitive (i.e. not yet exposed) layer applied and then through the projected measurement image or the double projector z. B. also by a red-green process projected pair of measuring images exposed.

Während des Auftragens der lichtempfindlichen Schicht ist aktinisches Licht in bekannter Weise zu vermeiden, z. B. indem man während dieser Zeit nur gelbes oder rotes Licht leuchten läßt.During the application of the photosensitive layer there is actinic Avoid light in a known manner, e.g. B. by only yellow during this time or let the red light shine.

Da z. B. bei einem Doppelprojektor die Projektoren, nachdem sie einmal zum Herstellen des Modells ihre richtige Stellung .erhalten haben, diese auch für die weiteren Arbeitsgänge, also bis nach der Belichtung der aufgetragenen lichtempfindlichen Schicht, beibeihalten können, so ist die Herstellung des Reliefs mit der Lichtbilddarstellung sowohl einfacher als auch genauer als das Verfahren, bei dem fertige Bilder gedehnt und nachträglich aufgeklebt werden.Since z. B. with a double projector, the projectors after once have received their correct position for making the model, this also for the further work steps, i.e. until after the exposure of the applied photosensitive Layer, so is the production of the relief with the photograph both easier and more accurate than the process of stretching finished images and glued on afterwards.
