  • Publication number: 20220091614
    Abstract: An autonomous driving module included in a mobile robot includes a distance sensor configured to shoot a signal toward a floor every predetermined time and measure the time it takes for the signal to be reflected and returned to generate a plurality of pieces of height information. A light source is configured to emit light toward the floor, and a camera is configured to capture the floor every predetermined time to generate a plurality of floor images. The autonomous driving module includes a processor configured to execute instructions and a memory configured to store the instructions. The instructions are implemented to synchronize the plurality of pieces of height information with the plurality of floor images, and remove a region generated by reflection of the light source from the synchronized floor images.

  • Publication number: 20210200232
    Abstract: A method is performed by a computing device including one or more processors and a memory that stores one or more programs executed by the one or more processors and includes acquiring a three-dimensional (3D) map of an interior, generating an occupancy height map by stacking spatial value histograms in a height direction while projecting the 3D map of the interior on a two-dimensional (2D) plane, and removing noise caused by a mobile object which moves in the interior from the occupancy height map.
