To determine the mean scale and distance disparities, we
ﬁrst randomly select M pixel pairs from the overlapping re-
gions and deduce their 3D positions under depth DR

Fig. 4. Examples of two inpainting strategies. The intuitive independent
inpainting strategy simultaneously performs rendering and inpainting for each
view. Due to there is no 3D constraint during 2D inpainting, the overlapping
regions inpainted in different views will be view-inconsistent, as shown in
the red box. In contrast, our progressive inpainting strategy achieves view-
consistent inpainting results by introducing NeRF as a 3D constraint and
reﬂecting previously inpainted content into the next view.
