Generation of roughness maps for three-dimensional (3d) objects

A method, comprising:

• in an electronic device:
• capturing, by use of a plurality of image-capture devices, a set of images of an object that is illuminated by a set of lighting patterns associated with a set of image light sources, wherein
• the set of images includes a set of polarized one-light-at-a-time (OLAT) frames that are captured from a plurality of viewpoints of the object;
• interleaving the set of polarized OLAT frames on the captured set of images based on the set of lighting patterns;
• executing a pixel-level inter-frame registration on the captured set of images, based on the interleaved set of polarized OLAT frames;
• generating a three-dimensional (3D) mesh of the object based on the captured set of images;
• generating a set of specular maps of the object in a UV texture space, based on the generated 3D mesh;
• and
• generating a roughness map associated with the object in the UV texture space, based on the generated set of specular maps of the object.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that when executed by an electronic device, causes the electronic device to execute operations, the operations comprising:

• capturing, by use of a plurality of image-capture devices, a set of images of an object that is illuminated by a set of lighting patterns associated with a set of image light sources, wherein
• the set of images includes a set of polarized one-light-at-a-time (OLAT) frames that are captured from a plurality of viewpoints of the object;
• interleaving the set of polarized OLAT frames on the captured set of images based on the set of lighting patterns;
• executing a pixel-level inter-frame registration on the captured set of images, based on the interleaved set of polarized OLAT frames;
• generating a three-dimensional (3D) mesh of the object based on the captured set of images;
• generating a set of specular maps of the object in a UV texture space, based on the generated 3D mesh;
• and
• generating a roughness map associated with the object in the UV texture space, based on the generated set of specular maps of the object.
