Title
(DE) VERFAHREN ZUR OBERFLÄCHENAUFNAHME EINES ROTIERENDEN KÖRPERS
(EN) METHOD FOR SURFACE RECORDING OF A ROTATING BODY
(FR) PROCÉDÉ DE PRISE DE VUES DE SURFACE D’UN CORPS ROTATIF
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Oberflächenaufnahme umfassend: Rotieren eines Körpers (1), insbesondere eines Werkzeugs oder Werkstücks, um eine Drehachse (2), und Aufnehmen einer Anzahl von a >1 drehwinkelversetzter Aufnahmen (6) während der Rotation des Körpers (1) mit einer Kamera (3) und z.B. einer Spiegelanordnung, wobei jede Aufnahme (6) einen anderen Teilbereich einer Oberfläche (13) des Körpers (1) abbildet, wobei die a Aufnahmen (6) zusammen einen Drehwinkelbereich m von bis zu 360° der Umfangsoberfläche (13) abbilden und wobei die a Aufnahmen (6) auf mehrere Umdrehungen des Körpers (1) verteilt werden.
(EN)
The invention relates to a method for surface recording comprising: rotating a body (1), more particularly a tool or workpiece, about an axis of rotation (2); and, during the rotation of the body (1), recording by means of a camera (3) and e.g. a mirror arrangement, a number of a >1 recordings (6), which are offset at an angle of rotation, wherein each recording (6) represents a different portion of a surface (13) of the body (1), wherein the a recordings (6) together represent an angle of rotation range m of up to 360° of the circumferential surface (13) and wherein the a recordings (6) are distributed over several rotations of the body (1).
(FR)
L'invention concerne un procédé de prise de vues de surface comprenant : la rotation d'un corps (1), en particulier d'un outil ou d'une pièce, autour d'un axe de rotation (2), et la prise d'un certain nombre a > 1 de vues (6) décalées en angle de rotation pendant la rotation du corps (1) au moyen d'un appareil de prise de vues (3) et, par exemple, d'un ensemble de miroirs, chaque prise (6) représentant une autre zone partielle d'une surface (13) du corps (1), les a prises (6) formant ensemble une plage d'angle de rotation m allant jusqu'à 360° de la surface périphérique (13) et les a prises (6) étant réparties sur plusieurs rotations du corps (1).
