High-definition map: Overview, Related Topics & Entities

A high-definition map (HD map) is a highly accurate map used primarily in the field of autonomous driving, containing details not normally present on traditional maps. HD maps are often captured using an array of sensors, such as LiDARs, radars, digital cameras, and GPS, and they can also be constructed using aerial imagery. Such maps can be precise at a…
