ALEXANDRIA, Va., May 12 -- United States Patent no. 12,625,269, issued on May 12, was assigned to Velodyne Lidar USA Inc. (San Jose, Calif.).

"Multiple resolution, simultaneous localization and mapping based on 3-D LIDAR measurements" was invented by Kiran K. Gunnam (Milpitas, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and systems for improved simultaneous localization and mapping based on 3-D LIDAR image data. In one aspect, LIDAR image frames are segmented and clustered before feature detection to improve computational efficiency while maintaining both mapping and localization accuracy. Segmentation involves removing redundant data before feature extraction. Clustering involves grouping ...
