Visual 2.5D perception involves understanding the semantics and geometry of ascene through reasoning about object relationships with respect to the viewer in an environment . Unlike general VRD, 2 .5VRD isegocentric, using the camera’s viewpoint as a common reference . Unlike depth estimation, it is object-centric and not onlyfocuses on depth . To enable progress on this task, we create a new dataset of 220k human-annotated . relationships among 512K objects from11K images . We analyze this dataset and conduct extensive experiments including benchmarking . multiple state-of-the-art VRD models . Our resultsshow that existing models . largely rely on semantic cues and simple heuristicsto solve 2. 5VRD
