Optically Assisted 'Find Phone' Using 3D Dwelling Model Captured Using Z Distance Aware Image Processing

When I use 'find phone' it usually tells me it is in my house by displaying a map of my road. This is frequently a bit annoying I have not been out the house since I lost it.
'Play sound' is great, but often, I cannot hear it.

    What I want is 'it is on the kitchen worktop downstairs' or 'on your car dashboard in the driveway' etc.

    The phone uses Z distance in video (e.g. from the dual aperture camera or by using multiple viewpoints determined using the phone's giro and visual cross matching) during a 'teaching' tour of one's house to build a rough volumetric 3D map of the internal spaces of the house. When activated, the phone uses the 3D image from the dual aperture camera of what it sees to match against the model of the internal spaces of the house to estimate its location which is communicated to the user. A full detailed model is not necessary, for example, Z distance is trivially available and the only flat surface that is XXcm from the ceiling is my kitchen worktop, and only the kids room has walls 3.2m apart etc.

    When one takes a new phone into one's house one takes it on a 'tour' of all the rooms with the (dual aperture) video camera on.

    The phone builds a rough 3D 'map' of the rooms, sizes, heights, doors, windows, flat surfaces etc. (many of which will be different distances from the ceiling) as well as noting the compass bearings as the video is captured and the giro indicated movement pattern/distance travelled.
