3d reconstruction with smooth maps

A non-transitory computer readable storage medium having recorded thereon a computer program that when executed by a computer causes the computer to implement a method for 3D reconstruction, the method comprising:

• obtaining 2D images which all represent a same real object which is fixed, and, for each 2D image, camera parameters which define a perspective projection;
• obtaining, for each 2D image, a smooth map, the smooth map having pixel values each representing a measurement of contour presence;
• and
• determining a 3D modeled object that represents the real object, the determining iteratively optimizing an energy that rewards, for each smooth map, projections of silhouette vertices of the 3D modeled object having pixel values representing a high measurement of contour presence.

A system comprising:

• a processor coupled to a memory and a graphical user interface, the memory having recorded thereon a computer program for 3D reconstruction that when executed by the processor causes the processor to be configured to:
• obtain 2D images which all represent a same real object which is fixed, and, for each 2D image, camera parameters which define a perspective projection,
• obtain, for each 2D image, a smooth map, the smooth map having pixel values each representing a measurement of contour presence, and
• determine a 3D modeled object that represents the real object, the determining iteratively optimizing an energy that rewards, for each smooth map, projections of silhouette vertices of the 3D modeled object having pixel values representing a high measurement of contour presence.
