Abstract

Conventional image scanners for large images are generally complex and expensive. Cheaper hand-held scanners can only scan narrow image strips, creating the problem of how to align the scanned strips in a large image. The problem is solved by mounting a hand-held scanner (1) in place of the pen in a plotter, and using software to drive the plotter to scan the image (2) in a regular, precise strip pattern. Accurate alignment can be achieved using standard slip-correction software for the plotter. ADVANTAGE - Cheaper than large image scanner with similar performance.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Übertragung flächenhafter Darstellungen, wie technischer Zeichnungen usw. in EDV-Anlagen, nach dem Oberbegriff des Anspruchs 1.The invention relates to a method and a device to transfer areal representations, such as technical drawings etc. in computer systems, according to Preamble of claim 1.

Das erfindungsgemäße Verfahren und die Vorrichtung zu dessen Durchführung eignen sich insbesondere zur genauen Übertragung der vom Lesekopf eines handy-scanners beim streifenweisen Abtasten einer Zeichnung aufgenommenen Daten in eine EDV-Anlage. Dies ist insbesondere für die Archivierung und Bearbeitung alter, handgefertigter techn. Zeichnungen notwendig.The method according to the invention and the device its implementation are particularly suitable for exact transmission of the read head of a cell phone scanner when scanning a drawing in strips recorded data in a computer system. This is especially for archiving and editing old, handmade techn. Drawings necessary.

Es sind bereits Scanner bekannt, die, an einen Plotter montiert, solche Zeichnungen insgesamt zu lesen und an eine EDV-Anlage zu übertragen imstande sind. Solche Scanner-Plotter-Anordnungen sind jedoch sehr aufwendig und daher teuer. Kleinere Scanner, wie z. B. sogen. handy-scanner sind zwar prinzipiell auch in der Lage eine Zeichnung zu lesen, jedoch nur streifenweise, wobei die Breite des abgetasteten Streifens der aktiven Breite des Lesekopfes entspricht. Beim Zusammenfügen der einzelnen Streifen zu einer Gesamtdarstellung, die der Originalvorlage zu entsprechen hat, ergeben sich insofern erhebliche Schwierigkeiten, als die Nahtstellen der einzelnen Streifen und somit die Linien der Zeichnung etwas versetzt sein können. Dies macht die übertragene Darstellung, ohne weitere zeit- und arbeitsaufwendige Bearbeitung, unbrauchbar.Scanners are already known which are connected to a plotter assembled to read and such drawings in total are able to transfer a computer system. Such However, scanner-plotter arrangements are very complex and therefore expensive. Smaller scanners, such as B. so-called. In principle, cell phone scanners are also capable to read a drawing, but only in strips, where the width of the scanned strip of the active Corresponds to the width of the read head. When assembling  the individual strips to an overall representation, which must correspond to the original template considerable difficulties in that the Seams of the individual strips and thus the Lines of the drawing can be slightly offset. This makes the transferred representation without further time and labor-intensive processing, unusable.

Hier setzt die Erfindung ein. Die Erfindung, wie sie in den Ansprüchen beschrieben ist, löst die Aufgabe, ein Verfahren und eine Vorrichtung zu schaffen, die die genaue Übertragung von flächenhaften Darstellungen, wie techn. Zeichnungen etc., in eine EDV-Anlage auf einfache Weise und kostengünstig durchzuführen.This is where the invention comes in. The invention as it is is described in the claims, solves the problem to provide a method and an apparatus which the exact transfer of areal representations, like techn. Drawings etc., in a computer system easily and inexpensively.

Die mit der Erfindung erzielten Vorteile liegen insbesondere in der Einfachheit des Verfahrens und der Vorrichtung.The advantages achieved with the invention are in particular in the simplicity of the procedure and the Contraption.

Durch den Einsatz des Lesekopfes eines kleinen Scanners, z. B. eines sogen. handy-scanners oder entsprechenden Gerätes anstelle des Stiftschlittens in den Kopplungsmechanismus eines Plotters, vorzugsweise durch eine einfach und rasch zu lösende magnetische Kopplung, kann jede in den Plotter eingelegte Zeichnung streifenförmig abgetastet werden. Die bei der Durchführung eines solchen Verfahrens mittels eines schmalen Lesekopfes zwangsläufig auftretenden Ungenauigkeiten an den Nahtstellen der einzelnen Streifen, werden durch ein integriertes Korrekturprogramm ausgeglichen, das die Geometrie des Scanners berücksichtigt (sogen. Slipkorrektur), sodaß die in der EDV-Anlage gespeicherte Darstellung exakt und bei der Ausgabe wieder lesbar ist, ohne irgendwelche Ungenauigkeiten der Linienführung an den Nahtstellen. Sie entspricht somit der mittels eines Großscanners abgetasteten Gesamtzeichnung. Die am Plotter vorgesehene Führungsschiene des Stiftschlittens wird für den Lesekopf des Scanners entsprechend genutzt und, durch eine Programmsteuerung, der Plotter und der Scanner synchron gesteuert.By using the read head of a small one Scanners, e.g. B. a so-called. cell phone scanners or equivalent Device instead of the pen carriage in the coupling mechanism of a plotter, preferably thanks to an easy and quick to remove magnetic Coupling, any drawing inserted in the plotter to be scanned in strips. The at the Carrying out such a process by means of a narrow reading head inevitably occurring inaccuracies at the seams of the individual strips, are compensated by an integrated correction program, that takes into account the geometry of the scanner (so-called slip correction), so that in the computer system saved representation exactly and at the output is readable again without any inaccuracies  the lines at the seams. It corresponds thus the one scanned by a large scanner Overall drawing. The guide rail provided on the plotter of the pen carriage is used for the reading head of the Scanners used accordingly and, through program control, the plotter and the scanner synchronously controlled.

Die erfindungsgemäße Vorrichtung ist anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigt:The device according to the invention is based on a the illustrations shown embodiment explained in more detail. It shows:
