1. Method for live construction of a video sequence, said sequence comprising an object modelled in three dimensions, wherein the method comprises steps for:
- pre-calculating data representative of at least one first image of a three-dimensional environment and a first item of depth information associated with said image,live calculation of;
data representative of at least one second image representing said modelled object on which is mapped a current image of a live video stream, said current image forming the texture of the modelled object, anda second item of depth information associated with said at least one second image, andlive composition of said sequence by combining said at least one first image and at least one second image according to said first and second items of depth information.

Abstract
The invention relates to a method for live construction of a video sequence comprising a modelled 3D object, the method comprising the following steps:
- pre-calculating data representative of at least one first image of a three-dimensional environment and a first item of associated depth information,
- live calculation of:
- data representative of at least one second image representing said modelled object on which is mapped a current image of a live video stream, and
- a second item of depth information associated with said at least one second image, and
- composing live said sequence by combining said at least one first image and said at least one second image according to said first and second items of depth information.
