From a Bird's Eye View to See: Joint Camera and Subject Registration without the Camera Calibration

arXiv:2212.09298v3 Announce Type: replace
Abstract: We tackle a new problem of multi-view camera and subject registration in the bird's eye view (BEV) without pre-given camera calibration. This is a very challenging problem since its only input is several RGB images from different first-person views (FPVs) for a multi-person scene, without the BEV image and the calibration of the FPVs, while the output is a unified plane with the localization and orientation of both the subjects and cameras in a BEV. …
