Abstract: A method in a computing device includes: in a facility containing a plurality of support structures, capturing an image of a first support structure; detecting, in the image, a first feature set of the first support structure; selecting obtaining at least one reference feature set by proximity to an estimated location of the mobile computing device in the facility coordinate system, the at least one reference feature set selected from a repository defining feature locations for each of the support structures in a facility coordinate system; comparing the first feature set with the at least one reference feature set; and in response to determining that the first feature set matches the at least one reference feature set, determining a location of the mobile computing device in the facility coordinate system based on the image and the feature locations from the repository.

Abstract: An assistive navigational system for deployment in a facility having a global frame of reference includes: a server including a memory storing: a plurality of anchor definitions each containing (i) an anchor position in the global frame of reference, and (ii) a feature set corresponding to physical characteristics of the facility at the anchor position; and a task definition containing (i) a task position defined relative to the anchor position, and (ii) task overlay data; the server further including a communications interface, and a processor configured to: select one of the anchor definitions for association with the task definition; and transmit the selected anchor definition and the task definition to a mobile computing device, the mobile computing device configured to receive the selected anchor definition and the task definition; the mobile computing device further configured to present the task overlay data on a display.
