The granted patent (Publication Number: US11835358B2) discloses a method and device for generating a local map representation of a road area using images captured by cameras associated with a vehicle. The method involves processing images to detect landmark objects, generating a three-dimensional representation of the landmark object, comparing the local map representation with a reference map, and selectively updating the reference map based on the local map representation. The device includes a processor configured to perform the method steps, such as detecting landmark objects, determining transformations for mapping objects between images, and updating the reference map with landmark observation information.

Furthermore, the patent details the characteristics of the landmark object that can be included in the reference map, such as location, orientation, shape represented by a 2D polyline, pose matrix for transforming the polyline into a 3D space, and a reference image describing the content. The method and device aim to enhance mapping accuracy by detecting landmarks in the environment, mapping them in three dimensions, and updating reference maps with accurate information. The technology can be beneficial for navigation systems, autonomous vehicles, and mapping applications that rely on precise and up-to-date map data for efficient and safe operations on the road network.
