Patent

CA 2695909

The invention relates to a projection device (1) that comprises: a projector (2) adapted for projecting a mother image along a projection axis (11); and a convex mirror adapted for at least partially reflecting the mother image and projecting it onto a three-dimensional environment (7, 8a, 8b) such as the ground, a ceiling, one or more side walls and the content of a room. When combining the projector with a convex mirror, the mother image can for example be projected into a solid angle higher than 2p steradians (i.e. a half-sphere), or even substantially equal to or slightly lower than 4p steradians (i.e. a sphere). The invention also relates to a method implemented by said device. The field of the invention is particularly that of video projectors for virtual or mixed reality applications.

La présente invention concerne un dispositif (1) de projection, comprenant : un projecteur (2) projetant une image mère le long d'un axe de projection (11); et un miroir convexe (3) réfléchissant au moins en partie l'image mère et la projeter sur un environnement tridimensionnel (7, 8a, 8b) comme le sol, le plafond, un ou plusieurs murs latéraux et le contenu d'une salle. En combinant le projecteur à un miroir convexe, l'image mère peut par exemple être projetée dans un angle solide supérieur à 2pi stéradians (c'est-à-dire une demi-sphère), voire même sensiblement égal ou légèrement inférieur à 4pi stéradians (c'est-à-dire une sphère). L'invention concerne aussi un procédé mis en oeuvre dans ce dispositif. Le domaine de l'invention est plus particulièrement celui des vidéoprojecteurs pour applications de réalité virtuelle ou mixte.
