    摘要： A system for generating a semantic 3D map, that includes at least one image capture device capable of capturing and transmitting digital frames of images; a temporal and unified panoptic segmentation module programmed, structed, and/or configured to receive the frames of images from the at least one image capture device and integrate a heuristic panoptic label fusion module with a loss function of a neural network to realize end-to-end panoptic segmentation; a geometric segmentation module programmed, structured and/or configured to receive the frames of images from the at least one image capture device and for discovering previously unseen scene elements, wherein at every frame, it generates a set of closed 2D regions and a set of corresponding 3D segments from a depth image; a segmentation refinement module programmed, structed, and/or configured to refine geometric labels using panoptic labels; and a 3D volumetric integration module programmed, structed, and/or configured to directly register each pixel of object segments into 3D space without checking the IoU ratio with historical information.
