Method for 3-dimension model reconstruction based on multi-view images and apparatus for the same

A method for reconstructing a three-dimensional model, the method comprising:

• obtaining n (n>1) multi-view images, and a second two-dimensional feature map and a second three-dimensional feature map, based on and n depth maps for the n multi-view images;
• estimating a texture through a texture prediction based on the second two-dimensional feature map and the second three-dimensional feature map;
• and
• applying the estimated texture to a mesh estimated based on a first two-dimensional feature map and a first three-dimensional feature map obtained based on the n multi-view images and the n depth maps to obtain a texture-applied final model.

A device for reconstructing a three-dimensional model, the device comprising:

• at least one processor;
• and
• at least one memory operably connected to the at least one processor, and storing an instruction to make the device perform an operation when executed by the at least one processor,
• wherein the operation includes:
• obtaining n (n>1) multi-view images, and a first two-dimensional feature map and a first three-dimensional feature map, based on n depth maps for the n multi-view images;
• estimating a mesh through an occupancy prediction based on the first two-dimensional feature map and the first three-dimensional feature map;
• and
• applying a texture estimated based on a second two-dimensional feature map and a second three-dimensional feature map obtained based on the n multi-view images and the n depth maps to the estimated mesh to obtain a texture-applied final model.
