PHOTOMETRIC STEREO SHAPE-AND-ALBEDO-FROM-SHADING FOR PIXEL-LEVEL RESOLUTION LUNAR SURFACE RECONSTRUCTION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Shape and Albedo from Shading (SAfS) techniques recover pixel-wise surface details based on the relationship between terrain slopes, illumination and imaging geometry, and the energy response (i.e., image intensity) captured by the sensing system ...

3D DIGITIZATION OF HERITAGE: PHOTOMETRIC STEREO CAN HELP [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 There are mainly two families of photographic 3D reconstruction. Photogrammetry techniques work according to the principle of triangulation, from the matching of different views, while photometric techniques link the appearance of a 3D point to the ...

Binocular Photometric Stereo [PDF]
Procedings of the British Machine Vision Conference 2011, 2011 This paper considers the problem of computing scene depth from a stereo pair of cameras under a sequence of illumination directions. By integrating parallax and shading cues, we obtain both metric depth and fine surface details. Casting this problem into the filter flow framework [16], enables a convex formulation of the problem, and thus a globally ...

Depth Super-Resolution Meets Uncalibrated Photometric Stereo [PDF]
, 2017 A novel depth super-resolution approach for RGB-D sensors is presented. It disambiguates depth super-resolution through high-resolution photometric clues and, symmetrically, it disambiguates uncalibrated photometric stereo through low-resolution depth ...

FCN-Based 3D Reconstruction with Multi-Source Photometric Stereo
Applied Sciences, 2020 As a classical method widely used in 3D reconstruction tasks, the multi-source Photometric Stereo can obtain more accurate 3D reconstruction results compared with the basic Photometric Stereo, but its complex calibration and solution process reduces the ...

Variational Uncalibrated Photometric Stereo under General Lighting [PDF]
, 2019 Photometric stereo (PS) techniques nowadays remain constrained to an ideal laboratory setup where modeling and calibration of lighting is amenable. To eliminate such restrictions, we propose an efficient principled variational approach to uncalibrated PS
