ALEXANDRIA, Va., Oct. 8 -- United States Patent no. 12,436,281, issued on Oct. 7, was assigned to Volvo Truck Corp. (Gothenburg, Sweden).
"Lidar localization using optical flow" was invented by Anders Sunegard (Gothenburg, Sweden).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method for determining a lidar sensor pose with respect to a predefined map image, comprising acquiring a lidar height map; determining an optical flow field, which relates the lidar height map and the map image; and computing a maximum-likelihood/ML estimate of the lidar sensor pose on the basis of the determined optical flow field. The optical flow field may optionally be determined by a regression model, which additionally produces...
