  • Publication number: 20220075068
    Abstract: A tightly coupled fusion approach that dynamically consumes light detection and ranging (LiDAR) and sonar data to generate reliable and scalable indoor maps for autonomous robot navigation. The approach may be used for the ubiquitous deployment of indoor robots that require the availability of affordable, reliable, and scalable indoor maps. A key feature of the approach is the utilization of a fusion mechanism that works in three stages: the first LiDAR scan matching stage efficiently generates initial key localization poses; a second optimization stage is used to eliminate errors accumulated from the previous stage and guarantees that accurate large-scale maps can be generated; and a final revisit scan fusion stage effectively fuses the LiDAR map and the sonar map to generate a highly accurate representation of the indoor environment.
