Patent number: 11688164Abstract: Systems, methods, and non-transitory computer-readable media can receive a geometric map and a semantic map associated with a geographic area, the semantic map comprising semantic data associated with vehicle navigation. A first semantic position estimate associated with a first piece of semantic data contained in the semantic map is generated based on semantic data location information associated with the first piece of semantic data. A final position for the first semantic position estimate is received. One or more three-dimensional semantic labels are applied to the geometric map based on the final position of the first semantic position estimate. A warped semantic map is generated. Generating the warped semantic map comprises warping the semantic map based on the one or more three-dimensional semantic labels.Type: GrantFiled: May 18, 2021Date of Patent: June 27, 2023Assignee: Woven Planet North America, Inc.Inventors: Patrick Dubroy, Wolfgang Hess, Clemens Marschner, Emil Praun, Holger Rapp, Thomas Schiwietz, Vinay Shet

Patent number: 11244500Abstract: Various embodiments of the present technology can include methods, systems and non-transitory computer readable media and computer programs configured to determine one or more images of a generated overhead view of a geographical area. The generated overhead view is generated from aggregated pixel values determined from correlated pixel values in images of the geographical area. The disclosed approaches identify semantic map features as being present in the images of the overhead perspective of the geographic area. The disclosed approaches extract the semantic map features of the geographical area from the images of the substantially overhead perspective of the geographical area. The disclosed approaches translate the extracted semantic map features to a semantic map layer of a geometric map associated with the geographical area.Type: GrantFiled: December 31, 2019Date of Patent: February 8, 2022Assignee: Woven Planet North America, Inc.Inventors: Clemens Marschner, Wilhelm Richert, Thomas Schiwietz, Darko Zikic

Patent number: 11163998Abstract: Systems, methods, and non-transitory computer-readable media can determine a first label at a first position in a first image captured from a vehicle, the first label indicating that a first object is depicted in the first image at the first position, wherein the first image is a two-dimensional image. The first object is identified in a three-dimensional coordinate space representative of an environment of the vehicle based on the first position of the first label within the first image. A second label is automatically generated at a second position in a second image captured from the vehicle based on simultaneous localization and mapping (SLAM) information associated with the vehicle. The second label indicates that the first object is depicted in the second image at the second position.Type: GrantFiled: October 22, 2018Date of Patent: November 2, 2021Assignee: Woven Planet North America, Inc.Inventors: Wolfgang Hess, Clemens Marschner, Holger Rapp
