Method and devices for visualising a digital model in a real environment

A method for visualization in real time of a three-dimensional virtual object in a real environment, the method comprising:

• reception of at least one video stream comprising a representation of at least one real object different from the virtual object;
• insertion in real time of a two-dimensional representation of said three-dimensional virtual object into said at least one received video stream while masking a part of the virtual object by the at least one real object as a function of a three-dimensional model associated with the at least one real object and of a position of the at least one real object, and creation of at least one augmented video stream comprising said at least one received video stream into which said two-dimensional representation of said three-dimensional virtual object has been inserted;
• reception of a video stream of a second type, said at least one video stream being at least one video stream of first type, said video stream of a second type enabling to determine dynamically the reflections of said real environment in said three-dimensional virtual object;
• update of at least one dynamic environment with data from said video stream of the second type, said data representing changes in the reflections of said real environment on said virtual object, said changes resulting from modification of said real environment or movement of said virtual object;
• combination of said dynamic management of said reflections with a static management of said reflections by combining said at least one dynamic environment maps with at least one static environment map according to their respective degree of influence;
• and
• transmission of said at least one augmented video stream.
