Abstract

The method involves using a monochrome laser. The laser scans the three-dimensional surface structure of three-dimensional elements that are still standing. The co-ordinates determined by scanning the surface are then stored. The scanning can be carried out using a scanning arrangement, deflecting the laser beam by a revolving mirror. Corresponding piece parts are cast or produced directly by milling using a CNC negative with the help of the three-dimensional co-ordinates obtained by scanning with the laser.

Description

Die Erfindung richtet sich auf ein Verfahren zur Erfassung von Stuck­ strukturen oder dergleichen, insbesondere zur Sanierung von Altbauten.The invention relates to a method for detecting stucco structures or the like, in particular for the renovation of old buildings.

Bei der Sanierung von Altbauten, vor allem von historischen Gebäuden, stellt sich oft das Problem, daß Stuckstrukturen der Fassade oder im Inn­ nenraumbereich, z. B. an Decken, nur noch in Fragmenten erhalten sind und deshalb zur Restaurierung die fehlenden Teilen rekonstruiert werden müs­ sen.When renovating old buildings, especially historical buildings, the problem often arises that stucco structures of the facade or inside nenraumbereich, z. B. on ceilings, are only preserved in fragments and therefore the missing parts must be reconstructed for restoration sen.

Hierzu geht man herkömmlicherweise so vor, daß die noch vorhandenen Strukturen abgeformt werden und aus den so erstellten Negativformen dann jeweils passende Teilstücke gegossen werden, die in die Stucklücken einge­ setzt werden.To do this, the conventional procedure is to ensure that the still existing ones Structures are molded and then from the negative shapes created in this way each matching sections are poured into the stucco gaps be set.

Ein derartiges in handwerklicher Arbeitsweise durchzuführendes Verfahren ist außerordentlich aufwendig, zeitraubend und kostenintensiv.Such a method to be carried out in a manual manner is extremely complex, time-consuming and costly.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfah­ ren der eingangs genannten Art so auszugestalten, daß Kosten gegenüber herkömmlichen Verfahren eingespart werden und auch großflächige Re­ staurierungen vergleichsweise schnell bewerkstelligt werden können.Proceeding from this, the object of the invention is a method ren of the type mentioned in such a way that costs compared conventional processes can be saved and large-scale re restorations can be accomplished comparatively quickly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die dreidimen­ sionale Oberflächenstruktur der noch vorhandenen Stuckelemente mittels eines monochromen Lasers abgetastet und die so ermittelten Koordinaten abgespeichert werden.This object is achieved in that the three dimensions sional surface structure of the remaining stucco elements by means of  of a monochrome laser and the coordinates determined in this way can be saved.

Die Koordinatenbestimmung kann entweder aus der momentanen Strahl­ richtung des Lasers und der aus der Laufzeit des reflektierten Lichtes er­ mittelten Entfernung oder durch Triangulieren bestimmt werden.The coordinate determination can either be from the current beam direction of the laser and the runtime of the reflected light mean distance or by triangulation.

Das Abtasten des jeweiligen Objekts kann am einfachsten durch eine Scan­ ning-Anordnung bewerkstelligt werden, die den Laserstrahl mit Hilfe von Drehspiegeln umlenkt.The easiest way to scan the respective object is by performing a scan ning arrangement are accomplished, which the laser beam with the help of Deflecting rotating mirrors.

Mit Hilfe der auf diese Weise gewonnenen dreidimensionalen Koordinaten können über eine CNC-Steuerung entweder Negativformen zum Gießen von entsprechenden Stuckteilen hergestellt werden oder die entsprechenden Stuckteile können aus einem Block mit Hilfe eines CNC-Frasers unmittel­ bar ausgefräst werden.With the help of the three-dimensional coordinates obtained in this way can use a CNC control to cast either negative molds of corresponding stucco parts or the corresponding Stucco parts can be cut from a block with the help of a CNC router be milled out in cash.

Ein erfindungsgemäßes Verfahren hat gegenüber herkömmlichen Verfahren den Vorteil, daß die einmal gewonnenen Koordinaten-Daten softwaremäßig beliebig bearbeitet werden können, d. h. es ist beispielsweise bei der For­ merstellung möglich einen Schrumpfungsfaktor mit einzukalkulieren. Wei­ terhin ist es durch Extrapolation möglich, auch solche Stuckbereiche zu rekonstruieren, die überhaupt nicht mehr vorhanden sind und deshalb nicht unmittelbar abgeformt oder abgescannt werden können.A method according to the invention has compared to conventional methods the advantage that the once obtained coordinate data in software can be edited as desired, d. H. it is for example with the For It is possible to calculate a shrinkage factor. Wei it is also possible to extrapolate such stucco areas reconstruct that are no longer there and therefore not can be molded or scanned immediately.

Die erfindungsgemäß abgespeicherten Daten ermöglichen eine beliebig häufige Reproduktion, so daß auch sehr umfassende und großflächige Stuckstrukturen rekonstruiert werden können.The data stored according to the invention make any one possible frequent reproduction, so that even very extensive and extensive Stucco structures can be reconstructed.
