[0111] The general principle of the present invention is based on extracting the corresponding 3D model stream that is associated with the irregular grid, adapts the content of the screen sequence, and takes into account the vertices of the irregular grid of the previous 3D model.
[0112] Refer to Figure 4 , You can simply recall the general principle of reconstructing video sequences with the aid of a three-dimensional model.
[0113] We study a real scene, in this case the object 41 (the teapot in the text) is photographed (42) by the camera 43. No assumptions are made about the nature of the camera, which can be mass-produced consumer products, and no assumptions are made about the acquisition parameters of the video sequence.
[0114] After the video sequence is digitized 44, a picture sequence 45 called the original sequence is obtained.
[0115] Through the analysis 46 of the original sequence, at least one 3D model 47 (a plurality of 3D models according to the present inv...
