OpenLane is the first real-world and largest 3D lane dataset to date. The dataset collects valuable content from the public perception dataset Waymo Open Dataset and provides lane and closest path object (CIPO) annotations for 1000 road segments. In short, OpenLane has 200K frames and over 880K carefully annotated lanes. The authors publicly released the OpenLane dataset to help the research community make progress in 3D perception and autonomous driving technology.
