Embodiments of systems and methods for concealing loss of Simultaneous Localization and Mapping (SLAM) data in edge cloud architectures are described. In some embodiments, a method may include: receiving SLAM data usable to produce a first map of a physical space for a first HMD; in response to a portion of the SLAM data being lost or corrupt, retrieving a first landmark detected in previous SLAM data with a first confidence value; receiving, from a second IHS coupled to a second HMD, a second landmark usable to produce a second map for the second HMD, where the second landmark has a second confidence value; in response to the first and second landmarks overlapping, selecting one of the first or second landmark with greatest confidence value; and producing the first map using the selected landmark.
