Abstract
Method and device for decorating a tridimensional object. The method consists of representing a three-dimensional model of the decorated object by a plotting of the decoration. It then consists of localizing on the object from the 3D model at least several characteristic points of said plotting so as to position, for example, adhesive decoration delimitation strips or stencils or precut decorative elements, etc. The invention is more particularly applicable to the decoration of an aircraft by logotypes, letters or distinctive signs on the outer surface of this aircraft.
Claims15
Method for decorating a tridimensional object consisting of:
- constructing a three-dimensional model of the object to be decorated by plotting of a desired decoration, said plotting being displayed by at least one image;
- localizing on said object at least certain characteristic points of said plotting from the model of the object and the plotting of the decoration, and modeling the decorated object comprising
- constructing a 3D mathematical model of the object to be decorated by means of a surface or volume type Computer Assisted Design (CAD), this model of the decorated object being able to be displayed by at least one image;
- superimposing on said model of the object at least one 3D mathematical model of the plotting of said desired decoration of the object, said plotting being displayed by at least one image and using positioning means on the object for delimiting the decoration on the object, from said characteristic points localized on the object.
Device for decorating a tridimensional object, comprising:
- a data processing system controlled by a specialized Computer Assisted Design software so as to obtain a tridimensional representation of a mathematical model of the object to be decorated by plotting a desired decoration and a tridimensional representation of a mathematical model of said plotting of said desired decoration of the object, the model of the decoration plotting being superimposed on the model of the object;
- storage means connected to the processing system so as to record the coordinates of at least a plurality of characteristic points of the plotting of the decoration and marked with respect to reference points of the object;
- and
- means to localize on said object at least the characteristic points of the plotting of the decoration from said recorded coordinates.
