| 摘要 |
The invention relates to a projection device (1) that comprises: a projector 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 2' steradians (i.e. a half-sphere), or even substantially equal to or slightly lower than 4' 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.
