Definitions

  • the invention relates to a method and an arrangement for measuring an object that is three-dimensional at least in partial areas.
  • Methods and arrangements of this type could be used, for example, to produce a precisely fitting shape for an object. In most cases, this measurement is done by hand, such as in the clothing industry, for measuring a tailor-made suit.

  • an experienced seller takes measurements and compares these measurements with his wealth of experience of the different sizes of different models of stock suits.
  • the invention is therefore based on the object of providing a method and an arrangement for measuring a three-dimensional object, at least in some areas, which ensures that an object is measured in a cost-effective, quick and simple manner.
  • This object is achieved according to the invention by a method with the features of claim 1 and an arrangement with the features of claim 4.

  • the lower or the rear object area can advantageously be measured with the same arrangement as the upper or the front object area.
  • this arrangement makes it possible to measure in a loaded state, since the lower object area is imaged under the influence of a force, for example by the weight of the object and / or a force m acting on the object in the direction of the shape.

Abstract

La présente invention concerne un dispositif de mesure (5, 7) servant à balayer un partie d'objet. Une autre partie d'objet est représentée et mesurée sous forme d'un moule (11) de forme au moins temporairement modifiable. L'invention fait intervenir l'utilisation de bandes lumineuses, de systèmes réfléchissants, de mousses.
