I agree it'll be amazing when device depth sensors can build up the occlusion mask on the fly, but that still requires a hardware upgrade (iPhone8?, android tango etc). IMO, the beauty of ARKit is getting reasonable AR tracking on the current crop devices (with a single camera lens!)

also, I think there are other ways to build up reasonable occlusion nodes manually. for example, its probable that the Google Maps iOS team is currently adding an AR directions view that use the Streetview point cloud to build up occlusion areas around most streets. Likewise, some areas of the OSM dataset include building footprints with height attributes, this could be used as well. No where near perfect but I think it would help in the situation you described above

Well the current iPhone 7s with its dual cameras can generate a realtime (albeit low-res) depth map in the iOS 11 beta, so you could probably get one working (probably somewhat crudely)
