We address multiview stereo (MVS), an important 3D vision task that
reconstructs a 3D model such as a dense point cloud from multiple calibrated
images. We propose CER-MVS (Cascaded Epipolar RAFT Multiview Stereo), a new
approach based on the RAFT (Recurrent All-Pairs Field Transforms) architecture
developed for optical flow. CER-MVS introduces five new changes to RAFT:
epipolar cost volumes, cost volume cascading, multiview fusion of cost volumes,
dynamic supervision, and multiresolution fusion of depth maps. CER-MVS is
significantly different from …
