| Abstract | TITLE: PROCESS FOR CONSTRUCTING A 3D SCENE MODEL BY ANALYSING IMAGE SEQUENCES. This invention relates to a process for constructing a 3D scene model by analyzing image sequences, ech image corresponding to a viewpoint defined by its position and its orientation. Calculating for an image a depth map corresponding to the depth, in 3D space, of the pixels of the image, calculating for an image, resolution map corresponding to the 3D resolution of the pixels of the image, from the depth map;matching a pixel of a current image with a pixel of another image of the sequence, pixels relating to one and the same point of the 3D scene, by projecting the pixel of the current image depending on its resolution and on that of the pixels of other images of the sequence matched with this pixel, constructing the 3D model fromt he selected pixels. |
