Abstract
A physical space includes humans and other objects. Humans may be dynamic in that they move while nonhuman objects may not move over time. An autonomous mobile device (AMD) determines which objects are human or other. Once determined, information about which objects are humans or not is used to provide functions such as facilitating interactions with people, determining accurate occupancy maps that do not incorrectly include the people, and so forth. Objects are represented as clusters, such as a two-dimensional arrangement of squares or a three-dimensional arrangement of cubes. Clusters are processed using one or more classification methods. If the classification indicates a human, one or more extraction techniques may be used to distinguish the portion of the cluster that is associated with the human object and that which is associated with a nonhuman object, such as furniture. The occupancy map, updated with nonhuman objects, may be used for navigation.
