Overview
LansAnchor gives two devices a shared spatial anchor from room geometry alone. One device scans a space and places an anchor. A second device scans the room on its own and finds that anchor in its own view of the room: no cloud needed, no camera images, no markers. It is designed for 2-4 cm anchor-local accuracy (measured 2.5-3.6 cm anchor-local RMSE, root-mean-square error, a standard way to score how well a fit lines up, on real cross-scan room pairs). Registration runs in seconds, entirely on-device.
Registration uses geometry only, positions and normals (the direction a surface faces), so it works from any mesh source. That includes ARKit scene reconstruction, HoloLens spatial mapping, or depth sensors in complete darkness. Color is never required. Every match is checked against hard verification gates (surface overlap, point-to-plane error, floor agreement, normal agreement) before it is ever reported as found. Low-confidence results are marked as such, never a silent guess.
