Relative Pose Estimation for RGB-D Human Input Scans via Implicit Function Reconstruction

Figure 4

Multiview optimization. Opt is the abbreviation of optimization, 2-view pose Opt in picture means our 2-view relative pose optimization, whose structure is as described in Figure 1; similarly, multiview pose Opt means our multiview relative pose optimization. We optimize the pose parameters hierarchically, just as the pyramid structure. We firstly optimize pairwise to get a coarse pose and then hierarchically align the whole views based on the coarse results via our proposed multiview optimization module.
