Abstract

In previously known methods, the measurement was carried out by optical measurement using a raster wall as a reference plate, the measurement having been carried out by means of a line grating projected from a certain angle. However, such a known method has the disadvantage that the recording of photos produced by double exposure is cumbersome and time-consuming and no automation is possible. The invention is based on the object of creating an improved method for body measuring, by means of which the disadvantages of previously known methods can be avoided. The object is achieved by a method which is characterised by combining the method steps of projecting lines on a body by means of a projector and the method step of recording the body with the lines by means of a video camera, which inputs the image for automatic analysis into a computer in which a reference raster already exists as program component.

Description

Die Erfindung betrifft ein Verfahren zur rechnerge­ stützten dreidimensionalen Video-Körpervermessung.The invention relates to a method for computing supported three-dimensional video body measurement.

Bei bisher bekannten Verfahren zur dreidimensionalen Vermessung plastischer Körper, insbesondere der mensch­ lichen Körpermaße wurde die Vermessung durch eine optische Körpervermessung mit einer Rasterwand als Referenzplatte und einem aus einem bekannten Winkel projezierten Linien­ gitter vorgenommen. Hierbei wurden durch Doppelbelichtung entstandene Fotos hergestellt, die dann von Hand ausge­ wertet werden mußten.In previously known methods for three-dimensional Measuring plastic bodies, especially humans body measurements, the measurement was made by an optical Body measurement with a grid wall as a reference plate and a line projected from a known angle grid made. This was done by double exposure created photos, which are then made by hand had to be evaluated.

Ein derartiges bekanntes Verfahren zur dreidimensionalen Körpervermessung weist jedoch den Nachteil auf, daß das Aufnehmen von durch Doppelbelichtung entstandenen Fotos umständlich und zeitraubend ist und daß eine Automati­ sierung des Verfahrensvorganges nicht möglich ist.Such a known method for three-dimensional However, body measurement has the disadvantage that the Take photos from double exposure is cumbersome and time consuming and that an automati Sation of the process is not possible.

Es ist auch bereits in Englang ein Verfahren zur drei­ dimensionalen Körpervermessung entwickelt worden, bei wel­ chem die dreidimensionale Vermessung durch einen Licht­ balken ermöglicht wird, der aus einem bekannten Winkel auf den Körper projeziert wird, der hierbei über die Fläche des Körpers bewegt wird, wobei er aus einer anderen Pers­ pektive von einer Videokamera aufgenommen wird. Die Aus­ wertung erfolgt hierbei durch einen programmierten Rech­ ner (Isis).There is already a procedure for three in Englang dimensional body measurement has been developed at wel chem the three-dimensional measurement by a light beam is made possible from a known angle the body is projected over the surface of the body is moved from another person perspective is recorded by a video camera. The out evaluation is carried out by a programmed calculation ner (Isis).

Auch dieses bekannte Verfahren weist den Nachteil auf, das die Herstellung von Doppelbelichtungen umständlich und zeitaufwendig ist und eine Laufzeit für den projezierten Strahl in Kauf zu nehmen ist und keine Automatisierung er­ zielbar ist.This known method also has the disadvantage that that the production of double exposures is cumbersome and is time consuming and a runtime for the projected Beam is accepted and not automation is aimable.

Der Erfindung liegt die Aufgabe zugrunde ein der­ artiges verbessertes Verfahren zur dreidimensionalen Körpervermessung zu schaffen, mit welchem die Nachteile der bisher bekannten Verfahren vermieden werden können und mit dem es ermöglicht werden soll, bei Vermeidung von Doppelbelichtungen und dadurch bedingtem Zeitauf­ wand das Verfahren auf unkomplizierte einfache weise durchzuführen und dabei eine Automatisierung des Ver­ fahrenvorganges zu ermöglichen.The invention is based on the object like improved process for three-dimensional To create body measurement, with which the disadvantages of the previously known methods can be avoided and to make it possible, if avoidance of double exposures and the resulting time the process worked in an uncomplicated, simple manner perform and automate the Ver To enable driving process.

Die Aufgabe wird durch die Merkmale des kennzeich­ nenden Teiles des Patentbegehrens gelöst.The task is characterized by the characteristics of resolved part of the patent request.

Das neue Verfahren zur rechnergestützten dreidimensio­ nalen Video-Körpervermessung kombiniert das Verfahrens­ merkmal der Linienprojektion und das Verfahrensmerkmal der Vidoeaufzeichnung. Das Bezugsraster wird von einem Rechner vollständig erstellt. Erfindungsgemäß ergibt sich der Vorteil, daß keine Doppelbelichtung und keine Lauf­ zeit für den projezierten Strahl (Isis) in Kauf ge­ nommen werden muß und daß eine automatische Auswertung von Körperoberflächen durch die verwendete programmierte Rechnereinheit erzielbar ist.The new process for computer-based three-dimensional nal video body measurement combines the procedure feature of line projection and the procedural feature the video recording. The reference grid is from one Computer completely created. According to the invention the advantage that no double exposure and no run Purchase time for the projected beam (Isis) must be taken and that an automatic evaluation of body surfaces programmed by the used Computer unit can be achieved.
