In order to pictorially depict three-dimensional objects, an object to be depicted (28) is photographed using at least one camera (24) from a number of camera directions of said camera(s) (24) in relation to the object (28) to be depicted. Two-dimensional image data of each camera direction is saved, together with the corresponding co-ordinates of the camera(s) (24) in relation to the object (28) to be depicted. The saved image data is reproduced from the perspective view to create a three-dimensional impression, by merging the two- dimensional image data whilst taking into account the corresponding co- ordinates. In order to fill in the image background behind the object to be depicted, a background surface is provided which has a substantially constant colour spectrum in the colour space. Said colour location is preferably luminescent (electroluminescent film).

L'invention concerne un procédé d'imagerie pour objets tridimensionnels, selon lequel le cliché de l'objet à imager (28) est réalisé par au moins une caméra (24) suivant une pluralité de directions de prise de vue par rapport audit objet. Les données d'image bidimensionnelles de chaque direction de prise de vue sont mises en mémoire, en même temps que les coordonnées desdites caméras (24) par rapport à l'objet à imager (28), et le rendu des données d'image mises en mémoire se fait en perspective, de façon à générer une impression tridimensionnelle, par un assemblage des données d'image bidimensionnelles tenant compte des coordonnées. Afin de remplir l'arrière-plan situé derrière l'objet à imager, on ajoute, avec une localisation chromatique sensiblement constante dans l'espace coloré, une surface d'arrière-plan qui est de préférence phosphorescente (feuille électroluminescente).
