GUIDANCE FOR COLLABORATIVE MAP BUILDING AND UPDATING

A collaborative map building method is described in which if it is determined, for example, by a SLAM network edge, that a portion of a map corresponding to a target area of a first region is incomplete, a request to a device is transmitted to move toward the target area. The map is updated based on the scan performed by the device in the target area. Also described is a virtual image guide embodiment in which upon determining that a map of a target area of the first region is incomplete, a virtual guide image is generated on a device to appear at a target location. The user of the device is guided to the target area by the virtual image.
