Further, surface measurements of walls and ceilings are made, and the area that is the location of the projection equipment, as well as the area of the room in which the effect will be observed, is evaluated. This is done in order to determine the sizes of fragments of images and the number of projectors for their projection.

The areas of overlapping light fluxes in the corners (joints) of the walls of the premises, floor and ceiling are specially evaluated.

Abstract

L'invention vise à assurer la possibilité de réalisation de l'effet d'une image panoramique circulaire utilisable dans la décoration de scènes de concert d'intérieur ou d'extérieur, de salles de concert ou de cinéma ou de salles et de scènes de théâtre en cas d'utilisation de murs ou de plafonds de locaux possédant des jointoiements à 90°. Selon l'invention, le procédé de formation d'une image panoramique circulaire dans des locaux ou scènes de concert d'intérieur ou d'extérieur ainsi que sur des scènes consiste en ce qui suit: analyser les locaux ou le terrain, déterminer sur cette base les fragments d'images panoramiques créées préalablement dont chacune est projetée par son propre projecteur et la quantité de projecteurs nécessaires à la projection, placer les projecteurs dans l'espace dans les angles morts des autres projecteurs de manière à ce que les fragments qu'ils projettent se rejoignent avec précision, avec condition préalable d'évitement de chevauchements entre fragments, de manière à assurer l'absence de déformations de l'images sur les jointoiements des surfaces de projection.
