  • Patent number: 12050471
    Abstract: A map generating system for autonomous movement of a robot includes a three-dimensional (3D) point cloud map input device, a 3D point cloud map regeneration device that extracts only 3D point cloud data corresponding to an arbitrary reference height from the 3D point cloud map to regenerate the 3D point cloud map, an unoccupied area generation device that extracts ground point cloud data from the 3D point cloud map to set an unoccupied area into which the robot is able to move, an occupied area generation device that extracts obstacle point cloud data from the 3D point cloud map to set an occupied area into which the robot is unable to move, and a two-dimensional (2D) map generation device that adds the unoccupied area and the occupied area to an area on the 3D point cloud map to generate a 2D map.

  • Publication number: 20220269273
    Abstract: An apparatus for estimating a position of a target may include a particle generator to generate a plurality of particles on a map, a particle selector to calculate position accuracy of each of the plurality of particles, based on data sensed related to a position of a target, and select, as a reference particle, at least one of the plurality of particles, based on the position accuracy, and a position determining device to determine the position of the target, based on the reference particle.
