Abstract
Maps of a physical space provide information to an autonomous mobile device (AMD) about the location of objects. For example, a local map may represent objects currently detected while a global map represents objects that persist over time. Disagreements between the maps may result from quantization errors, sensor errors, changes in the physical space over time that are shown in one map but not another, and so forth. For example, the local map may indicate an obstacle in a space that the global map indicates is empty, or vice versa. A cluster representing an object in a map may be assessed to distinguish if the object is actual or false. Other techniques may be used to determine disagreements. Information about persistent disagreements may be stored for mitigation. The AMD may mitigate disagreements by exploring the physical space associated with the disagreement to add to map data.
