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.
1 . A method comprising:
receiving a first transmission from a device, the first transmission indicating a first location of the device and containing first image data of a region;
determining, by control circuitry, that a map of a target area of the region is incomplete, wherein the map is generated based on the first image data received in the first transmission;
selecting a guide location in the first region, wherein, from the guide location, target area image data of the target area is capturable by an image sensor of the device;
transmitting a virtual guide image to the device, wherein the device displays the virtual guide image overlaid, at the guide location, on an image of at least a portion of the region or on a region map of at least the portion of the region;
receiving a target area data transmission from the device, the target area data transmission containing the target area image data of the target area captured at the guide location by the image sensor of the device; and
updating the map of the target area based on the target area image data.
