Abstract
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 England 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, und der hierbei über die Fläche des Körpers bewegt wird, wobei er aus einer anderen Per spektive von einer Videokamera aufgenommen wird. Die Aus wertung erfolgt hierbei durch einen programmierten Rech ner (Isis).There is already a procedure for three in England 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, and this over the surface of the body is moved from another person spective 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, daß 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 fahrensvorganges zu ermöglichen.The invention is based, one of the task 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 was straightforward and simple 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 dreidimen sionalen Video-Körpervermessung kombiniert das Ver fahrensmerkmal der Linienprojektion und das Verfahrens merkmal der Videoaufzeichnung. Das Bezugsraster wird von einem Rechner vollständig erstellt. Erfindungsge mäß ergibt sich der Vorteil, daß keine Doppelbelich tung und keine Laufzeit für den projezierten Strahl (s. Isis) in Kauf genommen werden muß und daß eine auto matische Auswertung von Körperoberflächen durch die verwendete programmierte Rechnereinheit erzielbar ist.The new process for computer-based three-dimen sional video body measurement combines the ver feature of the line projection and the procedure feature of video recording. The reference grid is completely created by a computer. Invention Ge moderately there is the advantage that no double exposure device and no runtime for the projected beam (see Isis) has to be accepted and that an auto matical evaluation of body surfaces by the programmed computer unit used can be achieved.
In der Zeichnung ist ein Ausführungsbeispiel der das Verfahren ausführenden Vorrichtung dargestellt. Es zeigtIn the drawing, an embodiment of the the device carrying out the method is shown. It shows
Fig. 1 eine seitliche Ansicht auf die das Ver fahren durchführende Vorrichtung; Fig. 1 is a side view of the drive by the Ver leading device;
Fig. 2 das auf den zu vermessenden Körper pro jezierte Linienraster in frontaler Ansicht. Fig. 2 on the body to be measured for each line grid in frontal view.
Ein aus einem bekannten Winkel von einem Linien projektor 1 auf die Oberfläche des zu vermessenden Körpers 4 projeziertes Linienraster 5 wird von einer Videokamera 2 aufgenommen, wobei die Informationen an eine Rechnereinheit 3 gehen. Die Hell-Dunkelinforma tionen werden in bezug zu einem in der Rechnereinheit 3 befindlichen Referenzraster gesetzt und automatisch ausgewertet. A line screen 5 projected from a known angle by a line projector 1 onto the surface of the body 4 to be measured is recorded by a video camera 2 , the information going to a computer unit 3 . The chiaroscuro information is set in relation to a reference grid located in the computer unit 3 and evaluated automatically.
Der zu vermessende Körper kann jeder beliebige Körper sein.Anybody can measure the body Be body.
Es kann auch der menschliche Körper zur Ver messung und Diagnose wirbelsäulenbedingter Ver änderungen sein.The human body can also be used for ver measurement and diagnosis of spine related ver be changes.
