Researchers have developed FlexMap, a new framework for constructing high-definition maps for autonomous driving that is adaptable to various camera configurations. Unlike previous methods requiring calibrated camera rigs and explicit transformations, FlexMap uses a geometry foundation model to encode cross-view 3D structure, bypassing the need for camera parameters as input. This approach maintains accuracy even with missing camera views or inaccurate pose estimates, as demonstrated by experiments on the nuScenes and Argoverse 2 datasets. AI
