Bird’s-Eye-View Panoptic Segmentation Using Monocular Frontal View Images
This repository contains the PyTorch implementation of the PanopticBEV model proposed in our RA-L 2021 paper Bird’s-Eye-View Panoptic Segmentation Using Monocular Frontal View Images.
Our approach, PanopticBEV, is the state-of-the-art approach for generating panoptic segmentation maps in the bird’s eye view using only monocular frontal view images.
